Regarding the WiFi (and Duma not lodaing) problem. I had same problem and found the solution... It is to reset the nvram. Here´s what I found.
"
Execute these commands through telnet into the router, courtesy of kamoj at snb.
WARNING: These commands will erase all your settings and should not be tried out if you are under warranty. Use at your own risk.
To make a real "Factory reset" issue these commands:
For the R9000 ( the mtd command does not exist so you should try these commands instead:
Code:
nvram default
nvram commit
ngmtd="$(awk -F: '/"netgear"$/ {print $1}' /proc/mtd | grep mtd)"
[ -n "$ngmtd" ] && flash_erase /dev/"$ngmtd" 0 0
reboot "
By the way, the R9000 command works on XR700 also
The trick is really if you can telnet into the xr700. The Telnet Enable line in the debug page http://routerlogin.net/debug.htm
was not there in ver 38, 36, 34 FW. But luckily I found it in 1.0.1.20.
Downgrade your FW under Firmware Upgrade in http://routerlogin.net/adv_index.htm if Duma OS doesn’t take you there.
Use your Windows command line to telnet into the Linux OS of the router.
