Error Codes Wan005 and Wan002

Have you found a resolution?  I have the same error code

Reseating it never worked for me, I haven't had the issue since yesterday I've put a fan underneath the unit and it seems to have mitigated the issue. My best guess is it's an overheating problem because after the unit is unplugged for 5 or so minutes the errors go away

Try putting a fan or something near it to keep it cool. To get the errors to go away I had to factory reset using the little pinhole button on the back. You could try unplugging it for a while and letting it cool down and plugging it back in

Try unplugging it from the wall and the unit and waiting for 10 minutes and plugging back in. If that doesn't work go for the hard reset

I have two home internet accounts and I'm wondering if it's a device issue. The grey cylinder one works fine and the black box one keeps having the issue this thread is about. The app won't even connect to it anymore even being on the wifi of the router. It's not an internet issue for me as the TV and phone connect just fine. But if I try to use the app or ethernet to a mesh wifi it stops working. If I plug other ethernet devices they connect to the internet. The Indian tech support is not helpful. And the app did not do an upgrade of firmware. 

Uninstalling and reinstalling the app and doing the setup again for the device connects the app but still no ethernet port for my mesh wifi but other ethernet devices connect just fine. Mesh being deco m5 which works fine with the grey cylinder home internet. 

I have the square box model with the no internet and WAN Error Code 5 issue.

I re-seated the SIM card by removing it and putting it back in the same way, but not closing the little rubberized flap afterwards. I suspect pressure from the flap may be pushing the SIM card slightly away from the ideal electrical contact position.

This worked for me, but may or may not be the issue, we’ll see over time, as this issue has plagued my service since inception, and if that’s all it was, it would be a blessing. Note that others say the other cylinder-shaped device does not have this issue, which led me to believe it’s something with the SIM seating improperly against the electrical contacts.

I should've stayed away after reading the reviews. Now I regret getting T-Mobile home internet service. Phone service is fine but home internet is horrible. Constant buffering (frozen now as Im typing this), bandwidth is low messages, "no internet connection" message even though the router shows 4 Bars with "your connection is very good" message. Most recently I've been getting WAN002 message. Too bad I've already paid my bill for this cycle but I'm going back to Spectrum before the next billing period. $30 bucks a month for T-Mobile home internet is certainly not worth the aggravation. Spectrum is most definitely worth the extra few bucks.
