Problems with Internet on Computer (DNS not working)

[AkumaX]

Alright, so I have a laptop with wired and wireless. Both connect to the router just fine, and receive an IP address and gateway fine also. However, I cannot access the Internet at all, no addresses or ports. But the weird thing is I can access the router no problem through Internet Explorer (192.168.1.1), but not FireFox. I can ping all other computers on the network as well. Any input would be very helpful, I've already asked an entire IT team and nobody has a clue.

edit: Also, I can connect to any IP address on the Internet, by using the IP address and not the Domain Name. It looks like DNS entries/lookup isn't working on my laptop. Help!

I hope that you are using the Wire and or the Wireless one at time and Not togather.

Try taking these steps:
In General you can debug the Network Setting of the computer following these steps.

Step One. Check the Network parameters in the Computer?s Device Manager. Make sure that the drivers are installed correctly; there is No IRQ conflict, and No Ghost installation. http://www.ezlan.net/faq#ghost

Step Two ? Verify Basic network setting in the OS: http://www.ezlan.net/Installing#verify

If the above two Steps indicates that every thing looks good but functionally it does not work.

Step Three. Check (and repair if necessary) the Socket Layers, Winsock, and or refresh the TCP/IP Stack. http://www.ezlan.net/clean#refreshnet

hey jack how's it goin

yeah, i did the wired and wireless one at a time. but i think i figured out the problem; my laptop isn't getting dns entries! i can't ping google.com, but i can ping 64.233.187.99, and access it just fine. so now im trying to figure out why this computer isn't resolving dns entries

router not delivering them. Find the dns entries for your ISP and manually assign them. If all starts working fine, then start digging through your router's config to find the entry that talks about DNS. It could be one of 2 things, either it sends (with the dhcp reply) it's own IP (192.168.0.1) or it sends whatever DHCP sent it for it's WAN port (direct to ISP's DNS)

i trie setting the dns entries to manual with the ones that the router got from the isp, but it still didn't work. i don't think it's the routers fault because of the 8 computers hooked up to the router (2 wired and 6 wireless), this is the only one that has problems.

Make sure that your DNS client service is running and set to automatic.

sounding like a virus or adware problem, tryin running ms antispyware and a virus scan, also try a small tool called CWSshredder to remove any crap like coolwebsearch as these adware progams are becoming very messy and cumbersome. I have seen situations like this which my answer has solved.

If your router is running DHCP and you using win2k/XP goto start run - cmd - ipconfig /all and make sure your getting a dns server allocated. If its a netgear router and your dns server is the same as your gateway then manually add the dns servers in the network connection as many routers fail to perform dns properly and the dns proxy crashes.


... my 2 cents
