I have just came across an issue that has never been an issue with the Thibor firmware I've used in the past. I have a GS 3.0 Router with Thibor 15C. I received a couple of messages trying to access different web sites where I was unable to connect to the site. I then tried the router address 192.168.0.1 and connected to the configuration page. I checked the status and the router had only been up for 2 days. I thought perhaps my internet connections was down, but I tried to access a web site again and could not access the site. When I tried the router 192.168.0.1 again, I could not get into the setup page. I tried to ping a web address (not an IP address) of my local cable modem ISP, and got no response repeatedly. I had to power my router down and then back up. Everything is functioning fine now. I cleared the NVRAM before the upgrade from 14 to 15 and then cleared the NVRAM after (don't recall the first build that I tried). I then did the 15b1, b2, b3 and then 15C. I DID NOT clear the NVRAM between different 15 build versions. No Peer to Peer networking or other high volume usage on the router that I know of that would cause this. Has anyone else been having a lock-up problem with this firmware?
