Cannot Communicate with DNS server

yes but i place my laptop right next to my computer which has a 54m connection which is G i think.. and thats always fine.

my bro has a G+ router and he gets low signal like the rest of us do but surely having no signal will effect the dns server.
i mean the dns server is a converter between addresses essentially from the router, if the DNS has a problem the whole network should fail, not just one pc...

seems a very odd problem with no real solution...

as ive already mentioned ive already spent £450 on it... i dont want to go out of my way to spending any more, thats it lol

I've a fairly similar problem to you but it effects the laptops we have - randomly cannot communicate DNS server. There are five laptops in the house most already have a wireless N card and all run Vista. Had the engineer out yesterday who couldn't explain the number of timeouts on the 50MB modem (as many as 17 or more everyday) but said it was fine. He did say that there is more than likely a problem with the Netgear wireless N router that is giving us the problem of randomly disconnecting from the internet (although local wireless is ok when this happens) the upshot is that I had to phone the 50MB broadband support line to get them to send a new router, hopefully one that works this time! Could this be your problem also?

Hi,

Can i just point out that the "can not connect to DNS server" message can be windows way of saying it has no internet connection, as when windows resolves an ip address it needs the DNS server and as it has no internet connection it says the old "can not connect to DNS server" so its likely you do not have a DNS issue, just no connection to the internet at the time.

The only reason i state this is i used to get customers thinking they had a DNS issue alot when infact they had no connection at all.

Just a little pointer.

Thx

Lucifer


PS: doing start then run and typing cmd to open command prompt and trying to ping the virgin dns servers is always a good test.

ping 194.168.4.100 <-- primary dns server
ping 194.168.8.100 <-- secondary dns server

Although in all honesty i dont use virgins dns servers.

NEONKNIGHT!

almost 100% exactly! wat router u got? DIR-615 by any chance? lol

and Lucifer there is no internet connection and yes thats the problem..
i cant ping any outbound services at all.
the router the dns another pc on the network nothing.

i know its a problem with the router set up now as it works when the pc is right next to it.
there is nothing else at all that has changed, so its the router. the DNS resolves on the other 3 pc's so no matter how many fails from the pc i get, the dns has to work for me to view any thing!

any1 else have the DIR-615? if so whats ur opinions on "supposed to be" one of the best types of routers?

So basically, what you're saying is that the PC has no network connection.

Does the little network icon down by the clock reflect this? If it is connected to the internet it should say "Local and Internet" on a mouseover and the icon should be two screens with a globe. If the globe is missing it will say "local only" on mouseover, and if there is no connection to a network, then there should be a red X.

If your PC is dropping signal with the router then that could be down to several things not just the router. What wireless card are you using?

[penfold1992]

the little icon at the bottom says LOCAL ONLY and the globe sign isnt there.... its connected to the router tho, in the network.

the NIC card i have is a Linksys N card. its about a week old and worked with the older router which was a G router. it now works next to the router... so unless im mistaken the only thing i can think thats the problem is the NIC card and the router.

as ive said the NIC card could pick up the older router and held a strong stable connection days on end. its just happened with this new router..

by deduction i stated that it was the router... i didnt blind guessed it was the routers fault

the problem lies within that connection as other pcs on the network are fine...

my bro is using a 128 G+ reciever... and his is fine and does not drop connection at all either

[penfold1992]

ok... now.... BREAKTHROUGH.

its def the router connection lol.

my bro got home and put his pc in his cabinate and it didnt work.... so we moved the router from behind the tv and now its below the tv and quite a lot more forward.

better connection. problem solved

thanks a lot for all your help!
