The router is already on channel 11. I used the M2 since it is all I have at the moment, but I plan on getting an actual access point if I can't get this figured out.

Also it is not always Verizon band 4, currently connected to band 13 and it is the same when I attach the antennas.

that is really bizarre. I wonder if that wifi chipset is just faulty or something.

This is strange behavior. Just to think out loud:

One, your antenna stats, while usable, are far from optimal. This requires the modem to work harder by increasing its power to compensate--which requires additional power from the router and on down to the power adapter. The MC7455 by itself can require up to one amp of power when under load.

When the WiFi is connected (which ultimately requires more power), it kills the throughput to the LAN.

I wonder if the power adapter is not providing enough juice to the router and modem? The power adapters that the factory provides with these units are far from being quality adapters.

Do you have a 12V 2 (to 3) AMP power adapter you can try on the unit. Most routers and similar devices use the same 2.1 mm tip barrel connectors.

This would be something simple to test. The lack of sufficient power can and does cause strange issues.

It comes with a supposedly upgraded 2000mA ac/dc adapter from when I bought it from ltefix.com. I don't know that I have one that is any more powerful.

The WE826-T2 routers are ordered from the factory with 12V/2 Amp power adapters as opposed to the 12V/1 Amp they normally ship with. That should not be confused with an upgraded adapter, or an adapter of higher quality. Most of the higher quality adapters are priced in the $10 to $20 range.

Also, I am not saying the power adapter is necessarily your problem although I have seen my share of cheap power adapters go bad. Only that it would be an easy fix to try.

I tried a ktec 2.5 amp adapter from my office business class frontier modem with the same results.
