Have a desktop that was working fine Wed evening and Thursday morning no connection

Tried to restore IP address but following error received:

Local Area Connection : unable to contact your dhcp server

I use RoadRunner as my ISP and use Linksys router

Tried going directly from modem to desktop to restore but no luck.

Have another laptop that connects perfectly through router LAN

Sony Vaio is desktop - please help!!!!

have you restarted your router..that is your home dhcp server.
its dhcp server is your ISP.
try everything power off for 10 secs and reload

after that if probs still persist..

go to start > run
type cmd
hit enter, you will load the dos prompt.

type "ipconfig /release" without the quotes and hit enter
then "ipconfig /renew" again no quotes and enter.

then try disabling the wireless adaptor or disabling the local area conection in the Control Panel > network conenctions menu (right click what one you are using and choose disable, double click after it becomes greyed out to re-enable it)

hmm im guessing roadrunner is US, so is your linksys box, i only have deep knowledge of one of their boxes..so im sorry i cant help much more, all i can think of is assigning a static IP to it, its a long process...ish and depends how computer literate you are

sure..

start > control panel > network connections > right click the one you are using..if its wireless choose wireless if its wired choose local area connection.
Right click and choose properties.

Choose Internet Protocol TCP/IP and choose properties.
Click the Manual assign circle and type ip address as
192 . 168 . 1 . 45
next box
255 . 255 . 255 . 0
next box
192 . 168 . 1 . 1

and the DNS boxes at the bottom type
192 . 168 . 1 . 1
next box
62 . 30 . 112 . 39

obviously click ok in all the boxes to save it :)

try that..i hope that helps?

ok thanks

what do i do after that - restart computer, router, modem?

BTW - while I am doing this does the modem need to be connected directly via ethernet to computer or through router?

How will it obtain another ip address so it is not the static one?

Erm..
putting this as simple as possible..

Your computer you assign a static..wont need DHCP..its got an address
Other PCs can get a DHCP address so they are all ok.
To do that you dont need to be connected to anything :)

restart all for good measure
