I recently flashed my E4200 V.1 firmware to Toastman's latest build (tomato-E4200USB-NVRAM60K-1.28.0502.1MIPSR2Toastman-RT-N-Ext.bin) and everything went smoothly. I did a 30/30/30 reset on the router and logged in to 192.168.1.1 w/ admin/admin.
Here, I enabled DHCP, named the 2.4GHZ and 5GHZ SSIDs, changed the admin password and enabled security. I am using an ATT Uverse modem/router in bridge mode with the wireless router disabled so I have to change the Cisco router IP to 192.168.2.1 for this configuration to work. I did that and saved.
My LAN internet and wireless internet are now working flawlessly at better speeds than the Cisco firmware, however now I am unable to log into the router at 192.168.2.1, I get an error that states the page is unable to load.
I've googled the problem and other users experience the problem when they do not enable DHCP, however I'm unable to find a solution addressing this particular problem.
Thanks in advance for any help on the matter.
