First have a look at the authoritative guide on R7800 (link in my signature) with important information about wifi if you go back to stock
If that does not help then sometimes when power is too low the first thing it affects is the wifi, so you can try another power supply.
But if something suddenly goes down without you not having changed anything and a reboot does not help it sure can point to a hardware problem

excuse me if its a hardware problem then why wifi(2ghz) is working with dd-wrt and openwrt but not with OEM rom??
because they use custom drivers? |
A few hints:
- Try flash the R7800 back to its first released stock f/ware to verify for certain if 2.4GHz wireless works or not. Fact: Later versions of stock f/ware of some of Netgear routers were designed to make flashing back to, or from, its firmware somehow corrupted in a move to discourage owners of its routers from using alternative f/ware.
- Given that you've already tried new power adapter with same result, I'd suggest you do a second s/w reboot of R7800 after flashing it with DD-WRT (|Administration|Management|Reboot Router). A 2nd s/w reboot seems to allow the router to be fully functional with its new DD-WRT OS.
You have nothing else to loose by trying the above and find out for yourself with certainty. |
