MC7455 and Visible by Verizon, Grammie help!

[gscheb]

Have you ever tried to tether the phone. Seen on here where someone was using Visible that way.

[terryjett]

No success yet.

I did the following:
1. Installed the MC7455 into the WE826GO-U
2. Booted the router and applied the following AT commands:
at!entercnd="A710"
at!usbcomp=1,1,1009
at+cgdcont=1,"IP","VSBLINTERNET"
at+cgdcont=1,"IPV4V6","VSBLINTERNET"
at!reset
3. Confirmed that APN was set to VSBLINTERNET
4. Enabled custom TTL and set it to 117
5. Rebooted the router

A constant ping against google yields 4 success, 3 fail, 5 success, 3 fail, 4 success, 3 fail, ... and nothing loads in browser at all.

I can put the sim into my phone (wifi disabled) and get 40 mbit down (from same location), and websites load correctly.

Might there be any more suggestions?

Visible did a two night software update (spread over a week) in their soft switch. Wondering if it might have changed things.

Have not tried setting up visible in my WE826GO / EM7455 yet but was planning to do so this weekend. Might be Sunday before I get to it, but will post back here how it went.

Would make sure you are running generic firmware though.

One other thing you can try is using custom firewall setting. Uncheck your 117 setting and enter this manually. Paste the below into "Custom Rules" (make sure there are no other rules and if they are, place a # at beginning of each line):

Code: Select all

#start naive newb fw
iptables -t mangle -I POSTROUTING -o wwan0 -j TTL --ttl-set 117
iptables -t mangle -I PREROUTING -i wwan0 -j TTL --ttl-set 117
ip6tables -t mangle -A POSTROUTING -o wwan0 -j HL --hl-set 117
ip6tables -t mangle -I PREROUTING -i wwan0 -j HL --hl-set 117
#end naive newb fw

I would also do a reboot (under System). Certainly worth a try

How can I check that the firmware is generic?

Also, I tried disabling custom TTL and applying your #start naive newb fw suggestion, and rebooted with no change.

Thank you for your help.

That looks ok. Very interesting. Going to try it myself and see what happens. Will report back my results.

Out of curiosity, what do you see when looking at Network / Interfaces? Do you get an IP4 assigned or does it look like this:

Also do a

and post results.

You might let the router sit (connected) for an hour and see if things change. Might do nothing for you, but at least you can see if anything changes.

[BillA]

Just a heads on on Visible's speeds, they are currently allowing up to about 40Mbps due to the Corona virus pandemic, but eventually are planning on dropping it down to below 10Mbps... we shall see. Latency will always be higher due to the data running through both Verizon's and Visible's sever. The more hops the higher the ping, there's no way around that.

I also have an AT&T SIM to test in this router. Do the AT commands that I issued need to be backed out for AT&T to work? I know that I need to update APN to broadband.

Thanks again for the input.

[hbr245b]

It's probably no help to you , but I just popped my Visible SIM into my USB enclosure, changed the connection profile in Rooter to VSBLINTERNET (previously broadband for my AT&T sim) and it just works. The USB enclosure is connected to a Raspberry Pi 3B+ running GoldenOrb_2020-03-01 ( OpenWrt 18.06.7 ). TTL is set to 65.

Speedtest showed 70ms ping, 51.40 download & 50.11 upload. I'm in NYC.

I'm hoping to roll out this config to my weekend house in rural upstate NY as soon as I can get some antennae to replace the current paddles I stole off a MOFI.

What modem do you have?

What modem do you have?

Sierra EM7565

Sierra EM7565

Wonder if Visible starting to block MC7455. Heard of Verizon blocking Mofi units which are MC7455.
Visible is owned by Verizon. Maybe terryjett will try his and see if it works or not.

[hbr245b]

To bring my post back on topic, my mofi has a MC7455 (I think - it's not powered on currently so can't check). The visible sim works in that too just by changing the APN name.

Not sure the topic you speak of, but without the type of modem your info has no bearing.

[foolhardy]

Maybe I should just buy a different modem? Currently I am unsuccessfully trying to get working the WE826GO-U with MC7455 on Visible.

Back to a previous question: I also want to test this hardware on AT&T. Do I need to “back out” any of those AT command issued to the MC7455 to test on AT&T?

[terryjett]

At heart, I am a experimenter. Started in 1965 when I disassembled by first AM radio. Go for it, try another modem.

[foolhardy]

Any recommendation on another modem to try with the WE826GO-U?

Hello again,
Don't know if this matters at all. Sounds meaningless but what the heck. The only difference between the mofi and yours is the mode you are in. The original commands had you go to MBIM mode and the mofi works in QMI mode.
Try these commands to go to QMI mode and see if it works.

The topic in question is MC7455 & Visible. I just did not know what modem I had.

I can confirm that my Mofi has an MC7455 and Visible works fine by selecting the correct APN from the drop down list and then rebooting the Mofi. TTL65, service mode LTE only.

Ping 77ms, download 46.59Mbps, upload 31.22mbps.

Thank you for the reply. I see that you have the SIM4 version. There are multiple versions including that, and SIM7, and V2.

I also tried the SIM4 version but could not make it work on visible.

My guess at present is that you must have just gotten a “good one.”

My apologies. I meant "Where did you get your firmware which you installed recently on your MC7455?"

The mofi web interface has an "internal module flasher" to update modem firmware. Presumably the firmware is downloaded from mofinetworks.com but I can't be 100% certain.

[foolhardy]

I think that, unfortunately, the WiFix firmware does not support modem firmware-flashing.

I have ordered a Mini PCI-E to usb adapter with SIM slot. I think that I should try this firmware:

Don't you already have the latest generic firmware already installed on your modem?

See your post: https://wirelessjoint.com/viewtopic.php?f=8& ... t=30#p8613

Stating the obvious here: I’m new to this.

Indeed I am running latest generic firmware. I was thinking that maybe the Verizon firmware might work better than the generic (?)

[hbr245b]

You could try the Verizon firmware. Is it already loaded in your modem? I'm not certain it will have any effect though.

Just to re-iterate: I haven't run any AT commands to make changes to the modem. I just set the correct APN via the web interface & rebooted. Generic firmware selected on the modem.

I ran the following commands on my modem to try to get it to work with visible:

at+cgdcont=1,"IPV4V6","VSBLINTERNET"

Might that be causing me problems? My modem currently is in MBIM mode, As it will not connect at all in QMI mode.

Hello got this from home Sierra wireless MC7455 tutorial section.

There may be times were one needs to restore the modem to its OEM configurations. This will effectively reset any changes you have made to the modem's settings.

To restore to OEM settings:

at!entercnd="A710"
at!RMARESET=1

[BillA]

For those who are still having difficulty connecting on Visible, from what I've read they work off of IPV6 only, so try this which will also set it to auto-scan and LTE only. You may also have to try both QMI and MBIM modes.

Code: Select all

AT!ENTERCND="A710"
AT!BAND=00
AT!SELRAT=06
AT!CUSTOM="IPV6ENABLE",1
AT+CGDCONT=1,"IPV6","VSBLINTERNET"

Hello was wondering what TTL was used to get these speeds?
Currently the only person I know using it doesn't have TTL custom settings and getting the throttled 5 download speed.

Hey gscheb,

I was using a router with custom golenorb firmware provided by Rooter (ofmodemsnandmen . com) with a MC7455 modem with the generic software installed. I'm assuming between the router and the modem, Visible is unable to tell that I am using it as a hotspot.

I have been trying to get Visible working in a WiFiX-NEXQ6GO (new version of WE826)with EM7455. Followed Mr Bill's steps and looks like it is going to connect, but never quite makes it. Looking at debug output I think it is going to connect, then it stalls with:

Anyone experience the same and have a solution?

Have tried both MBIM & QMI modes with no luck. MBIM seems to get closer but no cigar

I could have sworn had 02.33.03.00 on this modem but after doing the AT!RMARESET=1 ended up with the wrong version / mismatch. Looks like it is time to reflash. No time this evening for pulling modem from router and reflashing. Wish I could remember at! command to swap preferred / current...

Will report back progress for future generations...

[terryjett]

I blindly jumped in not thinking that I have EM7455's based off the Dell versions. When I did the AT!RMARESET=1 it wrecked the modem. Even worse my dumb arse did it to two of the modems, lol. Late night mistake, should have been in bed.

So if you are not using the MC/EM7455 directly branded by Sierra Wireless, do NOT use the command AT!RMARESET=1 or you will be starting over from scratch. It set the modems back to dell dragonfly and one of them went into low power mode for some reason. Now I have to attempt to recover them...

[arbyyyyh]

AT! Commands for setup:

at!entercnd="A710" : Establishes admin access to Modem
at!usbcomp=1,1,1009 : sets MC7455 to MBIM mode, required for most interfaces (routers)
at+cgdcont=1,"IP","VSBLINTERNET" : sets APN as visble (seems that capitalization matters)
at+cgdcont=1,"IPV4V6","VSBLINTERNET" : allows for IPV4V6 use... this was a setting that seemed to "enable" my service.
at!band=0E,"VZW (All)",0,000000000000101A :notice the 101A, this is a binary representation of all the band values above.

Just created this account after bashing my head against the wall for 2 days so that I could say that I think this fixed my issues. I've been using an EM7455 with a VZW Postpaid jetpack sim to great success but when I put in a Visible SIM, statistics made it sound as if there wasn't even a network to connect to. I had done everything else at lesat 5 times before, but despite working on VZW, I think the last command there is what did it for me. Thank you! I was about to start looking into an unlimited plan on verizon which is much more money than the $25 that I'm hoping to get down to

So if you are not using the MC/EM7455 directly branded by Sierra Wireless, do NOT use the command AT!RMARESET=1 or you will be starting over from scratch. It set the modems back to dell dragonfly and one of them went into low power mode for some reason. Now I have to attempt to recover them...

Terry, I believe the Dell branded EM7455s just need to be reassigned to the current firmware version. For some reason it goes into low power and mismatched firmware. It sometimes borks it Ive heard, but usually putting it in a sled and sending a few commands like IMPREF= ..... then AT+CFUN=1,1 will get it done

I can ask a buddy who does these all the time now how he deals with them.

Thanks! I have not picked them back up as frustrated with myself for screwing them up, lol.

Love to get your buddies advice on easy method to reset the Dell branded EM7455.

Got a few more coming over by slow boat from China so any advice is appreciated.

I asked. Ill let you know what he says.

If you muster up some courage, you many want to try these methods to convert to generic Sierra model.

Unzip the guide and open the .MHT file in any browser.

There's also a nice Control Center app available for the EM/MC7544

Thanks Bill!

I have these in my arsenal. Matter of fact how I convert most all the dell branded modems (which I use in setting up faster internet for teachers).

What I was hoping, was to try a simple fix as described by @Didneywhorl. Might be a new trick for an old dog and this old dog needs a few new tricks:)

Ok, I am all good on the two EM7455's. I sat down and ran through both modems using my ole standby method which Jim wrote up some time back in a Google doc. Thanks to all who gave me tips.

[nontheist]

Just wanted to say thanks to everyone in this thread. I've been on Calyx with a very poor connection for the last few years. My wife and I switched our main phone service to Visible this year and I just looked at switching our Calyx service to Visible and found this thread. I'm using an MC7455 on a WE876 with regular antenna whips in the house and I'm getting better reception than my external antenna! Wow!

Hello terryjett,
Know you have experience with EM7455 modems connecting to Visible. We could use your help over at this thread if you would please help.

If you have fairly good Tmobile coverage in your area, then the SimpleMobile $50 plan will give you the best speeds I've seen on any carrier (average 100Mbps down, and 50Mbps up).

You can buy a sim card and activate it at your local SimpleMobile dealer (https://www.simplemobile.com/findastore).
They just fool you online with that $45 auto-pay price, after adding a bunch of taxes it comes out to over $50.
Since my credit card got stolen twice already on their website, and even got double billed, I'm only paying by cash. Dealers usually charge a flat $50 cash, and you can even prepay multiple months ahead if you wish. Best of all, it keeps your account completely anonymous (dealers don't ask for your info;). There's no contract, so if it doesn't work you can always try something else.

Hello BillA, this is very useful to know. In a few months I'll be in the USA for a few months, and I'll need LTE service. Same as you, given all the hacks, I don't want to give carriers my personal information. It is my primary concern and I only want to use carriers that will allow me to stay anonymous. Do you know if any other prepaid carriers besides SimpleMobile will let you get up and running without submitting your information?

You should be able to sign up anonymously by going to a local Tracfone dealer, they usually carry all the carriers (SimpleMobile/Tmobile, Net10/ATT, PagePlus/Verizon). Enter the zip code of the location you happen to be in https://www.tracfone.com/findastore. Pick one of the smaller dealers, and as long as you're paying cash, usually they don't ask for any info. I can also active any of those carriers through my dealer account, but of course you need to use a PayPal account for the monthly service.

Does the simplemobile carrier you posted earlier have the same latency issues as visible does using Verizon?

SimpleMobile uses Tmobile towers with truly unlimited data for only $50/month. I've been using around 500gigs/months for the past 5 years, and seen others go over 1,000gigs (that's 1 TeraBytes/month) without any issues. Speeds and latency are on par with a regular Tmobile Magenta plan. I can also turn off video throttling through my dealer account without any additional monthly fees, unlike on direct Tmobile plans. There's an old adage "You get what you pay for."

Much like other carriers in the US, Verizon uses the TTL method for detecting tethered traffic, so the easiest way is to change it in the router running either GoldenOrb or WiFix firmware. Unfortunately I haven't seen a way to change TTL in a NightHawk M1 router yet.
If using an external modem in a USB adapter Mini-PCIe/M.2 antenna housing tethered to a Windows PC, you can set the TTL on the PC quite easily via these CMD commands (you may need to play around with the value from 64 to 66 but 65 is what seems to work best):

netsh int ipv4 set global defaultcurhoplimit=65
netsh int ipv6 set global defaultcurhoplimit=65

Once your have the data connection working on the PC properly, you can try using something like Windows10's Mobile Hotspot or Connectify to share the connection sort of like a software router (the TTL settings might still be an issue for sharing... ymmv).

This post was referenced in a thread I created https://wirelessjoint.com/viewtopic.php?f=15&t=2653. I'm fairly certain I am doing everything right but I've been unsuccessful with my t-mobile line. I CAN get it to work when the sim is in my MOFI, set to 65 TTL but not when tethering to my PC from a phone.

I'm wondering if the iPhone is telling on me or there's a new step that's needed. I have an older Android but I'm thinking that shouldn't matter.

Thanks

Hello, trying to get Gma some decent internet in the boonies w/ Visible by verizon.

Previously, I had an Unlimited LTE sprint card in an MC7455(PCI/USB/Antenna adapter) routed to a TP-link with Rooter installed (ofmodemsandmen). This worked great. I pulled 100+ mbps.

NOW I have Visible unlimited, through verizon. I am trying to use the guide here: viewtopic.php?t=33

to set my MC7455 up. I have not been successful though!

Background:
SIM is activated, it is my phone sim. Works great on my iphone.
The plan is unlimited, with unlimited hotspot (speeds capped for unlimited, but going to try and work around that)

Just like for sprint, I am testing this on my Windows 10 machine w/ Skylight installed prior to attempting the Rooter Router.

I have installed the latest generic firmware (PTCRB & GCF Approved—Release 26).

I have tried different APN configurations "vsblinternet" "VSBLINTERNET" "vzwinternet"

I have tried IPv6 enabled/disabled per the guide above

I have tried using Verizon's Sierra Driver

and finally, I have toggled IPv6 on an off for the APN's above. (all while OEM resetting the router/refashing generic firmware between variations of AT! commands).

IF ANYONE COULD JUST POST THE SERIES OF AT! COMMANDS I WOULD NEED TO IMPLEMENT A WORKING SESSION THAT WOULD BE GREAT.

Thanks in advance
