| 548877 | 2007-05-10 11:29:00 | Hi everyone, I've got a Dynalink RTA770 router, with two PCs connected, each connecting to the internet via the router, both running XP. Yesterday, the main computer just decided to not connect to the internet. I tried rebooting the router, rebooting the computer, but still nothing. Second PC connected okay. I figured the router might need to be reset, so I used a pin to return router to factory settings. Then second PC wouldn't connect. I eventually got the second PC back online - I went into the TCP/IP properties page for the LAN connection, and entered the DNS settings manually. However, when I try this on the main computer, it just hangs. If I reset the computer, the settings are remembered, but still won't connect. A website I found suggested it might be a corrupted winsock entry (whatever that is), and downloaded something that deleted it and replaced it with a clean one (leap of faith here...) But still no luck. The main PC won't even connect to the router (192.168.1.1) admin page. I've tried swapping the cables from the working PC, but it doesn't make any difference. Any ideas? |

| 548878 | 2007-05-11 01:03:00 | Checked for malware on the non-connecting PC? Resetting the router was pointless - the other PC didn't have a problem so that should have told you the router was OK. Do an ipconfig and see if it has been assigned the correct IP> Shouldn't need to mess about with DNS settings either. |

| 548879 | 2007-05-11 04:44:00 | for most people the DHCP option is easiest - also known as "obtain an address automatically" as long as the router supports it that should be all you need to do You can right click on the network connection and select "repair" and let windows try and fix it, sometimes works. You can uninstall / re-install the network adaptor either physically or in software to see if that works. You can go into the tools connections option in internet explorer and check that it somehow hasn't changed to dial-up, should say "never dial a connection" or some such. There's also a LAN settings button that might be useful in the same location. Altough it's not the best tool you can run windows network setup wizard and see if that sorts the problem out. There's always the chance that your network cable or adaptor has actually gone faulty, if it's an add in card try pulling it out and plugging it back in and make sure it's well seated. You could try swapping cards / switch ports / cables etc between the 2 machines and see what happens. Be methodical, 1 thing at a time and try to pin down the cause. |

| 548880 | 2007-05-11 06:52:00 | Thanks guys, I'll try those things, but I think the pertinent problems are the inability to access the routers admin page, and the response when I try and change the TCP/IP settings. If one computer can access the router's admin page, but not the other, that suggests the network adaptor is stuffed. I'll investigate the other possibilities first, though. | Lizard (2409) | ||
| 548881 | 2007-05-11 06:54:00 | Checked for malware on the non-connecting PC? Do you recommend a particular program? I usually use Ad-Aware and Spybot... |

| 548882 | 2007-05-11 11:55:00 | Thought I had a clever idea - see the RTA770 router has 4 ethernet ports and a USB port. I had both computers connected via the ethernet ports, when it occured to me if the ethernet port on the computer was faulty, I could hook it up via the USB port. I quickly installed the drivers, then connected the cable. Nothing. It should have come up with the auto-detect wizard, but it just sat there, sullenly. So I tried the same USB setup on the second computer, and it worked perfectly. So... 1st computer - won't connect to router's admin page, internet, or ping 2nd computer. Fails using either ethernet or USB 2nd computer - working fine connected to same router, via ethernet. If the 1st computer had connected via USB, then I would have concluded the ethernet port on the 1st computer was faulty, but if USB fails as well, then that suggests something more widespread is wrong with the 1st computer - but what though? |

| 548883 | 2007-05-11 11:59:00 | Another update - tried uninstalling the network adaptor, but it just hangs when I click OK. Similarly, when I use the Add Hardware wizard, it just endlessly searches (going on 15 minutes now) Something seriously screwy is going on here - motherboard on the way out? | Lizard (2409) | ||
| 548884 | 2007-05-11 13:19:00 | hmmm... should have suggested before try system restore back to a date before the problems. Not a great believer in the powers of system restore but it's worth a crack. Also Spybot and Adaware both ok programs - keep them up to date. For spybot under tools switch on advanced mode go to tools startup - go through the list and read the descriptions acessed by clicking the tab on the right. Sometimes this shows you things the scan misses, be careful though. Definately sounds screwy but my first suspicion would lean towards software - the USB & Ethernet are very diff beasts to have the same problem because of hardware. Do you use a firewall? could it be causing your problems? have you installed any new software lately etc etc |

| 548885 | 2007-05-11 13:31:00 | System restore as suggested above. And also try hijackthis. | Blacky (12247) | ||
| 548886 | 2007-05-12 07:42:00 | All fixed now - threw in a network card from a friends computer, and it connected no problem. It must have been the ethernet port on the motherboard. Though the fact the USB cable didn't work still has me puzzled. Is it possible that something on the southbridge is damaged? Although other USB devices are working... | Lizard (2409) | ||
