I get a 404 - page not found error when I try to access my router setup. Dlink DGL-4300 router. IPCONFIG says 255.255.255.0 subnet and 192.168.0.1 gateway and 192.168.0.99 IP. Running XP Home SP2.Tried resetting router, nothing. Tried auto/manual TCP/IP config, nothing. I think I have tried everything I could think of. Pleas somebody help me. Called DLINk, they had me do everything I have already done and then I think they hung up on me? Lost connection or something. Can ping router at 192.168.0.1 and access web but not router. Really strange. Thanks in advance.
This really is a "long shot", but you don't have another adapter (wireless or wired) in the computer that is configured with the address 192.168.0.1? This would normally cause an IP address conflict, but it is just conceivable that you are not pinging the router but a network adapter. Similarly, is there another PC with that address, possibly configured as the result of previously using "Internet Connection Sharing"?
Could it be MALWARE that has corrupted your computer and blocked. I suggest you take your modem to a fresh PC or laptop, link it up with an ethernet cable, change IE options connections to never dial and LAN to auto and see if you can access the router setup page 192.168.0.1
If you can't then it looks like router fialure, as any PC should easily be able to log into the router.
Cant access router with another computer either. Both computers "seem" clean, checked with adaware and mcafee. The router is only about 2 months old. Should be under warranty. Thanks for all the help, apperciate it. If you think of something else, let me know. Thanks again.
