wg3526-GO2018-09-02 modem disconnecting

[Nycto]

Running the latest firmware (wg3526-GO2018-09-02) on a wg3526 and my mc7455 modem keep disconnecting after 12+ hours of working fine. Each time, the modem won't go back online till I pull/replace the power cord, even a software reboot doesn't seem to help. This last time I grabbed some logs:

Do you have Connection Monitoring enabled with modem reconnect?

[Nycto]

Yeah I have the connection monitoring enabled with modem reconnect. After this hard reboot it's still acting funny, it keeps cycling on/off and won't go stable. I see it getting an IP but it won't pass the ping check now.

In dmesg you can see the device cylcing, of note is a page fault:

Maybe I didn't leave it powered off long enough this time.... maybe hardware issue, tho it's all new equipment... maybe go back to the 2017 firmware?

What would be the best firmware I can go with?

Also for the mc7455 firmware I followed the linux automated flashing tutorial:

Code: Select all

ATI
Manufacturer: Sierra Wireless, Incorporated
Model: MC7455
Revision: SWI9X30C_02.24.05.06 r7040 CARMD-EV-FRMWR2 2017/05/19 06:23:09

Thanks for the help!

Check the modem again to make sure it is in MBIM mode

[Nycto]

Seems like its in mbim mode to me:

Code: Select all

at!usbcomp?
Config Index: 1
Config Type:  1 (Generic)
Interface bitmask: 0000100D (diag,nmea,modem,mbim) 

I disabled the modem reconnect on the connection tracker, now the modem isn't cycling in and out but the connection is still unusable. Everything seems to indicate the modem has made a connection, but I can't ping or route out to the internet. I can try moving the sim back to the hotspot it came with, but my phone on the same carrier as no issues on the same tower so I imagine the hotspot will work as well.

[JimHelms]

When it was stable for 24 hours, was it then on Band 25?

Your cellular signals (RSRP) are not very strong in your previous GSTATUS. Have these changed any?

Have you tried to relocate the router to a different location?

[Nycto]

Yeah Band 25 seems to be the best one here and the one it was connected to for the last few days. I've tried moving the location of the router but it only makes it worse (i.e. band 26). In this spot I can get 10mhz on Band 25 when everything was stable before I went to bed last night.

This refusing to connect is completely new since that last crash I had. Although I was looking at antennas to hopefully grab Band 41 and get an increase of speed, I've been doing speed tests all day long over the weekend, getting 10-20m down and 5-7m up on average. If I go down the road in either direction about 100ft I can pick up Band 41 but not a trace of it on my property, go figure.

I don't have the raw numbers, but on the status page I saw between 45-55% signal, between that, SSI and RSCP things are normally reading 'medium'.

Edit: Moved the sim over to the R850, in the same spot, connected on Band25 and able to use the internet without issue. Attached the stats from that device for comparison.

[JimHelms]

Are you using the stock 4G antennas that comes with the WG3526?

I am not sure how good of antennas they actually are. It may be worth upgrading to some better antennas or even an external antenna setup.

[Nycto]

I'm using thesehttps://thewirelesshaven.com/shop/antennas/indoor ... ennas-sma/ now and plan to order the Cisco ones with the base extentions that I can put into the attic or 2x omni outdoor antennas once the store re-opens.

For now I still can't get this device to go online again now that I've moved the sim card back. I did a PRL and Data Profile update while I had it in the hotspot for good measure. I get both an IPv4 and IPv6 address, but still no internet routing. If I leave the connection monitoring set to modem reconnect it just cycles endlessly. If I set it to just 'Enabled' its forever showing DOWN but modem itself is stable so I can issue AT commands without TIMEOUT errors.

With lack of a better idea I think I'm going to move off this firmware revision. When I got this device I flashed wg3526-GO2017-12-15, then wg3526-GO2018-08-17. Both worked and connected fine, but ddns on each wasn't working (click add, then would get a blank screen) so when I went to post about that I saw 09-02 and tried that one too.

Is there a stable/recommended firmware for the WG3526? I remember seeing a reference in other posts to an April release that had some WiFi fixes perhaps?

[JimHelms]

Is there a stable/recommended firmware for the WG3526? I remember seeing a reference in other posts to an April release that had some WiFi fixes perhaps?

HERE is a list of all the releases.

[Nycto]

Awesome, thanks for the link.

I did a factory reset last night and after going back though the setup process it's been stable again for 14 hours and counting.

[JimHelms]

That is good to hear. So I suspect it could have been related to either something in the configuration or more likely, in Sprints network.

Either way, that was a good move to reset and start over. Keep us updated.

[Nycto]

My modem went into a timeout state again today with a crash log to go with it. For what it's worth, my WiFi has also been kinda finicky, I don't think the 5gz side is working correctly, devices have a hard time staying connected, and in the case of a Macbook, will cycle refusing to connect for 10-15 minutes till it will finally get connected on the 2.4ghz side. Since my last post the only settings I've mucked with is the WiFi settings trying to solve this.
