I recently upgraded the firmware from 220.127.116.11 to 18.104.22.168 and when the router rebooted the interface was
missing many items. On the basic setup page the boxes were missing to set the local ip address, subnet mask and anything
below that. On the Wireless Security page the security mode box was half it's size and did not have any options in it. The wireless isolation
wpa algorithm, preshared key and key renewal boxes were missing too. I rebooted the router and still got the same thing. I was able to get into
administration and reset to the factory default. Once the router rebooted I was unable to get into the interface at all. It wouldn't come up at all.
The power and light were blinking but I was unable to connect to it. I tried to connect with 192.168.1.245 and the one I had set manually but no
luck with either. I was able send back the router for an exchange with Cisco. I received the new one today. It started up and everything worked great.
I decided to try the firmware upgrade again. I went from the firmware version that was on there(I didn't right down) to 22.214.171.124 and the upgrade worked
as the other 3 I have. I than tried the 126.96.36.199 upgrade and I got the same thing as the other router I sent back.
Has anyone had this issue before? This is very frustrating. I have 3 other routers in place that I will not be upgrading at this point. I should not have
tried the upgrade again on the one today but being a bank the examiners like everything up to date and it's part of the monthly check.
