DSL wifi disconnecting

[#1]

I have a westel  D90-327W15-06 router that has started disconnecting my Wi-Fi after around 20 minutes.  If I hardwire to the box I get internet. Turning it off for a few minutes sometimes fixes the problem.  I have tried two other routers gt784wnv and a dsl-2750B and get the same result so I am convicted it is something Verizon is purposely doing because they want me to get rid of the dsl and pay $$$$$$$$$$$$$$$$ for fios.  I have tried looking on the Verizon website for a firmware update but it is nonexistent. Calling Verizon send me to inda which is of no help either.  Has anyone else had (and fixed) this problem?

Most modem combo's Wi-Fi sucks.

It would be better to this...

#1 Get your own RJ-45 WAN port NAT router.

#2 Make sure that the WAN Port of the RJ-45 WAN port router works.

#3 Put the RJ-45 WAN port router in the most central place of the house/business (if it is not there already). Note: Where central also means, not top floor/bottom floor - not just center the other way.

#4 Put the modem combo into bridge mode. See REF = http://www.dslreports.com/faq/13600

#5 Profit. 🙂
