Re: My Ultimate LTE router using a Raspberry pi 4B

Came back to find information on how I made this work. I should have posted a followup. Basically, after I got this all set up, I realized that there's no legit way to get an unlimited data plan on AT&T or Verizon. Sprint/T-Mobile has no tower anywhere close to me. Starlink put a nail in this pr...

Re: Upgrading my current setup with Raspberry Pi

I wouldn't underestimate what the pi is capable of, especially the pi4. The pi4 has gigabit lan and usb 3.0 and there is firmware for all versions of the pi floating around. It was even powerful enough to run OMR which I had used to bond 4 separate providers and use as my main home router. Only dow...

Re: AT&T Ipad Plan and Equipment Used

I'll warn you all that there's no production-ready "canned" router software for the RPi4. There is a daily snapshot of OpenWRT, and a couple of community builds.

If you want to build a RPi4 router, see my build thread in the Open Discussion section.

Re: My Ultimate LTE router using a Raspberry pi 4B

Update: I've been testing some more. When left to defaults, the modem will do carrier aggregation with band 66 and some other band which escapes me at the moment. I do remember that the secondary band was one of the 700-800Mhz bands. This resulted in download speeds of around 16Mb, but upload speeds...

Re: AT&T put their routers on the moon?

I now believe my huge latency was caused by the modem overheating. I noticed that while I was testing the EM7655 went to 65 degrees.

After powering down for a while and back up, the latencies were back to normal values.

No. Raspberry Pi4 running OpenWRT. Sierra Wireless EM7565 in a USB3 M.2 enclosure (with extra USB connection for extra power). Two Wilson Electric yagi antennas.

It looks like a very juicy lightning rod.
I have a couple of VERY tall trees close to the house and the antenna should fall within the cone of protection of those trees. However, I am going to add a ground just to be safe, just haven't done it yet.

I'm running OpenWRT on a raspberry pi4 with a EM7565 modem attached via a USB enclosure. I find that after powering up, the modem may or may not respond to commands, or may respond partially. Sending an "AT" to the modem does not get an echo, but the modem will reply "OK". Here's...

AT&T put their routers on the moon?

I've got my RPI4/EM7565 router up for testing. I'm seeing RSSI in the -77dB to -85dB range. Speetest.net and fast.com shows me getting 10-12 Mb downloads and 2 up, which I'm thrilled with (my DSL is 3Mb/768k). What I'm not thrilled with is latency. Both speedtest and fast.com reports my latency at a...

Re: My Ultimate LTE router using a Raspberry pi 4B

Some things to report:

Wifi is broken in the RPi4 builders of OpenWRT. There's some patches that fix this issue in the mainstream linux kernel needed to fix this, but they haven't made it over into the OpenWRT version yet. I'm not using wifi, so no worries for me, but I thought I'd pass it along.

Re: Raspberry pi 4B and a modem in a USB enclosure power questions

... I'm also toying with the idea of scrapping the RPi and associated software and instead use pfsense on a small x86 system.... pfsense is almost certainly out of the running. The only way FreeBSD (the OS under pfsense) supports LTE modems is via ppp. That limits performance to the 20mb/sec range.

Re: Raspberry pi 4B and a modem in a USB enclosure power questions

Another option: don't use the cheapest possible injector... 16w is very very low-end.. 30w is still fairly cheap, and 60w exists... You can also use 2 usb cables from the pi to the enclosure (1 for power + data and 1 for extra power only). It's not that simple. The old 100mb method of PoE was to ju...

Re: POE Splitter for WG3526 (non-P version)

You need to be careful here. There are two common PoE specs: IEEE 802.3af-2003 and IEEE 802.3at-2009. The af flavor only supplies 16 Watts of power. The at flavor supplies 25 Watts. If you want more than 16 Watts (actually only 12.5W at the device), you need to insure that your PoE splitter and inje...

Interesting. I've was trying to sign up with a somewhat local provider for AT&T 400GB service. I was all ready to pull the trigger and they informed my that they were "out" of AT&T. They could only sign me up for their cheaper T-Mobile plan.
