WE826-T2 and MC7354, No Internet

[terryjett]

Just setup new WE826 and MC7354. The MC7354 was used and pulled from working router few months back.

Have ran through the troubleshooting and all seems good. SIM is reading and certain pigtails are connected firmly / correctly. AT&t SIM is good, just pulled it out of working 781S hotspot before this setup. Modem is connecting too.

Here is little debugging info:

Any tips that may get me on the right track appreciated.

I did see this tread https://wirelessjoint.com/viewtopic.php?f=21&t=34 but do not yet have my USB to PCI yet. Figured must be another issue because the MC7354 was working on AT&T few months ago.

[terryjett]

Forgot to mention that I flashed the new WE826 with openwrt-we826-GO2019-10-20-upgrade.bin so not running stock.

Also using SIM from a 781S hotspot and it had been connecting to bands 2 and 4 without any issues (using at&t prepaid ipad plan).

[JimHelms]

What carrier firmware is on the MC7354?

Pulled the MC7354 from working router few months back.

Wondering if I should replace the AT&T firmware with the generic firmware? Really like to see this setup working.

[JimHelms]

If it were me, I would first reset the MC7354 modem to OEM. This is wipe out any configuration that may be the culprit.

With that said, do so at your own risk. If the modem was originally in a Verizon device, it may resort back to Verizon firmware and will again need to be flashed with AT&T firmware.

Code: Select all

at!entercnd="A710";!RMARESET=OEM

After the reset is complete, you may have to reboot the modem. Some of the MC7354 auto reboots after the OEM is performed.

Code: Select all

at!reset

After the OEM is completed, you need to do a hard reboot of the router (power off/power on).

When all is rebooted and the modem is again available, remove all the APN's from all profile slots on the modem:

Code: Select all

at!entercnd="A710"
at+cgdcont=1;+cgdcont=2;+cgdcont=3;+cgdcont=4

Next, and assuming you still have AT&T firmware, hard program the APN as well as make sure it is entered in GoldenOrb's MODEM PROFILE.

Code: Select all

at+cgdcont=1,"ipv4v6","broadband"

If you still have issues connecting, and you have a Mini PCI-E to USB adapter, flash the modem with the latest AT&T firmware. I generally flash the modem twice with a firmware.

[terryjett]

Thanks for reply Jim.

I did as you suggested and still no internet. Looking at the debug and other info seems I should. Only thing seems strange is transmit power in debug:

Beat me. Can remove the SIM from we826, install in the netgear 781S and instantly connects to band 2 (sometimes band 4) with pretty good speeds of 17-20 down and about same up.

Hoping to start replacing netgear 7XX in field with we826 but right now the test is disappointing:(

[JimHelms]

Run the command:

It is also possible that the AT&T SIM Card is using an IPV4 APN as opposed to an IPV4V6 APN.

IP4... Could that be it? Should there be any IP's shown here?

2019-10-28_155703.png

Will take a look at the IP4 tutorial you suggested.

[JimHelms]

Your signals are not real good, but they should hold a connection.

You are registered with the network but in idle mode.

I would try changing the APN to an IPV4 per the tutorial and see what happens.

[terryjett]

Yes, using the stock we826 antennas until get it working. Be little better when I hook outside antennas.

Will try the IP4 fix now and report back.

[terryjett]

IP4 change did not fix. Modified my existing create_connect.sh. After comparing the one from rar to my existing using notepad++, there were differences so thought best to keep mine and just modify it.

At loss on next steps / what to do.

Does this mean anything from logs:

[JimHelms]

It still shows that IPV6 APN is being used.

Open two web browsers, each with GoldenOrb.

Open the AT Command Terminal on one of them, and the Debug on the other.

Manually program the IPV4 APN and watch on the Debug window that it is going through. See if it will connect without being in idle mode.

Using two browser windows and running command see this in debug window:

Its holding. Just curious, log into your ATT account and see if the MC7354 is showing up.

[terryjett]

Do not see any place for showing devices. Using the ipad prepaid plan (mentioned in second post - hope this is not the issue). Got to test it as 99% of the low income families we setup are/will be using it.

Do know that few devices out in field using MC7354 are successfully connecting to the prepaid plan. According to installer all they did was pop in card and worked.

[terryjett]

What do you think about flashing generic firmware in place of at&t firmware?

Really does not make sense to me why not working as is, but if going to use the we826 / mc7354 in future need to get working in this test setup.

[terryjett]

Well darn, guess I have worn my welcome out

[JimHelms]

Well darn, guess I have worn my welcome out

Nope, not at all. Just have to divide my time between the forum and other matters.

There was someone on the hacks facebook group that referenced having to call AT&T and have them reactivate the plan after changing devices. This may be worth trying.

As for trying the generic firmware, I do not see you have much to lose at this point. But, I would give AT&T a shout using the phone number tied to the plan.

[terryjett]

I understand Jim, you cannot babysit me, lol.

I can try calling at&t, but can move sim between: galaxy s5, galaxy s8, netgear 781s, netgear 815s and netgear LB1120 without any issues - instantly activates and internet works.

Going to try the mc7700 in we826 tomorrow. If that fails, do not know next step.

[terryjett]

Last night went to friends home and we popped the MC7354 into his setup (usb adapter connected to asus router) and internet worked within minutes. Confirmed the MC7354 is good.

Woke up this morning determined to get the MC7354 working with my brand new WE826.

Jim suggested: Called AT&T and was told there is no issues, account does not need reactivation. After little prodding got the nice girl to check the imei. Sure enough she read back the imei of the MC7354. So, the issue is not AT&T best I can tell.

Placed MC7354 in usb adapter and followed instructions ( https://wirelessjoint.com/viewtopic.php?f=21&t=34 ) to flash generic firmware. All went well:

Code: Select all

BUT, STILL NO INTERNET for connected devices.

For grins, downgraded the WE826 firmware and results are exactly the same. No internet.

I am pretty tech savvy. Worked for Nortel Networks (until they went belly up) for quite a few years. Matter of fact was on team in Washington state that tested the first Nortel CDMA equipment. Started in the 800MHz single channel radios all way to start of LTE, so no stranger to cellular. My point is setting up the WE826 is not not easy for all:)

I had asked earlier in this thread if any IP's should be shown in network and did not get answer:

2019-10-30_090546.png

Going to try the MC7700 later today, If the results are the same, could I have a bad WE826?

[JimHelms]

The issue is the network has the modem in idle status.

Code: Select all

EMM state:     Registered     	Normal Service 
RRC state:     RRC Idle

You might do a search on the forum for "idle status"

AT&T showing the IMEI of the MC7354 is a good sign only if the SIM Card and plan is for the MC7354, or its IMEI is being ignored for the plan.

The router is doing its job and so is the modem. Not sure why it is being placed in idle status.

[terryjett]

Could you tell me what this command does:

AT+CGEQNEG=1
ERROR

Keep seeing it in debug window. Shows up and then disappears.

[terryjett]

Crazy stuff. Just put in the old MC7700 and works perfectly. Beats me. Going to grab a couple more of the MC7354 later and try again. Even crazier, the one that does not work for me, works for another at&t prepaid plan.

Could anyone suggest a card like the MC7354 (covers bands 2 and 4) with lowest cost?

Trying to save money so we can provide more free accounts to low income families with kids. Equipment / installation costs eating the budget up:)

[gscheb]

Hello,
Think it would help with advice we could we know what your goals are.
How much you trying to spend per device?
What do you want this advice to do? (how long range for example)
Do these setups require outside antenna or they in strong service area?
What kind of performance are you looking for?
There are some cheap options out there but think allot of people on this site looking for performance.
Never used this before but it sells on amazon for like $150, and has the bands you mentioned.
https://www.amazon.com/GL-iNet-GL-X750- ... B07RQ6JXJC
The other thing is I have seen people on ebay selling used MC7455 cards for example that you can put into a router.

[terryjett]

Thanks for reply @gscheb!

> How much you trying to spend per device? the group that offers this service to low income families pays for everything, including two years of service for the selected families. so you an imagine they would like to keep the cost low as possible. i am not privy to exact amount (finances) they have spent in past. only trying to help them put a standard (or close) setup together at the lowest cost.

> What do you want this advice to do? (how long range for example) we are rural. do not need help with antenna choice, got that covered. the setup should connect to at&t bands 2 and/or 4. Nothing fancy, only provide internet so kids can use to learn and help with homework. they or course use it for other purposes:)

> Do these setups require outside antenna or they in strong service area? devices will of course have to connect to external antennas. we have a supplier for yagi's and cabling.

> What kind of performance are you looking for? we only wish to provide basic internet access so kids can use to learn and better do their homework,. if they can stream movies, so be it but that is not the sole purpose.

Really all I am looking for at this point is MCXXXX (or maybe EM) cards that cover at&t bands 2 and 4. Cannot seem to find a good band comparison chart for the MC.
