Hi
I purchased the router 3 days ago, installed it and for those 3 days there is no problem. Yesterday I upgraded the firmware, and since then Windows 7 has big problems connecting the WAN on the computer (wired, not wireless). The Win7 Troubleshooting advises the computer is trying to connect to a DNS that doesn't exist or is incorrect.

However, I can get to the internet via the Wifi using my smartphone. But there is no PC wired connectivity. The router's GUI appears to show WAN disconnect, reconnect in a cycle.

I have disabled IPv6. Also flushed DNS, ipconfig / release, ipconfig / renew. I don't know if any of these worked to get me connected. But if I reboot the router, I lose WAN connectivity all over again.

Note that NONE of these problems occurred prior to the firmware upgrade.

Connection: PPPOE ADSL (Auto detected)
System: Win7/32
Modem: Nectomm NB6 full bridge
PC: wired via LAN
