Losing_grip · Post by **Losing_grip** » 15 Jun 2008, 07:42

The story is , my sister used the school internet free wifi access and the guy incharge there change some stuff in her laptop. When she came back home , she cant longer connect to our wireless router. Shes using firefox so i went to tools -> option -> advance -> network -> settings -> shes using manually configuration , so i changed it back to direct connection settings.

But still no luck. I tried to disable all the active connection and reconnect. Tried it again but i restart the laptop this time. Still no luck. i also tried ti pinging websites using msdos. I tried to use internet explorer still doesn't work. Tried using Other users still no luck. It's directing to proxy. It said Oopss cannot be found website and some other message that might cause the error. and the Url is redirecting to http:\\urlsleeves.com\somethin\google.com
when i tried to enter google.com

Shes using Windows XP sp2 build in wifi connection.

But when shes @ school. she can hell connect without having any problem.
Any ideas? Thanks

Have you checked her IP settings? Did she have to use custom IP settings (DNS server, IP, subnet, etc.)?

Also, is your router using DHCP? Do you need to set IP addresses manually?

can you ping the router? what's the output for ipconfig /all?

@Starvos
Yup , i checked her ip settings , its on automatic obtain ip address. No she doesn't need to use any custom settings to connect to our router. Nope , we don't need to set up any ip address.

@B_B

Yes i can ping it.

hm, ok, no bad config to find there....I am pretty sure it's the router and NOT the computer.
what's the output for:

Code: Select all

tracert google.com

The DHCP/DNS server should be the ISP's DNS/DHCP server I think.

type into cmd prompt

ipconfig [enter]

iprelease [enter]

iprenew [enter]

this should fix the dns settings

also change the node type to broadcast

DNR

Broadcast Node Type
For a small LAN with no name server, Broadcast, or B-node, makes the most sense. Broadcast simply resolves by broadcasting an address query to all computers on the subnet, then responds promptly with "name not found" if no response is received from the broadcast.

Note that Broadcast, and the variants of Broadcast (Hybrid / Mixed), depend upon packets broadcast over NetBIOS Over TCP (NetBT). Make sure that your DHCP server, if you have one, is setup to enable NetBT. If you're on a small LAN with a NAT router providing DHCP, make sure that NetBT is explictly Enabled on each computer, and make sure that all personal firewalls are properly configured for NetBT. Without NetBT, you'll need a DNS server, for name resolution.

Also note that the effect of NetBT Broadcast name resolution is much more pronounced on a large LAN with slow network speed, or with congestion. In a small LAN, with modern, high-speed components, the effects of NetBT broadcast will be minimal. For most small LANs, NetBT Broadcast is a perfectly acceptable method of name resolution.

>> Top

Hybrid Node Type
Node type Hybrid, or H-node, will work on a small LAN, but it may cause response issues. Hybrid queries the name server first, using directed NetBT, not broadcast NetBT. If there is no name server, the computer has to wait for the name server query to time out, before trying to resolve by Broadcast.

>> Top

Mixed Node Type
Node type Mixed, or M-node, will work on a small LAN, but it may cause response issues when trying to resolve invalid names. Mixed tries Broadcast first, then queries the name server if no response is received to the broadcast. If a computer with the desired name does not exist, the computer has to wait for the name server query to time out before responding with an error 53, "name not found".

>> Top

Peer-Peer Node Type
Node type "Peer-Peer", more appropriately called "Point-Point", is a problem on most small LANs. That means MyComputer requires a WINS server to resolve names. No WINS server means no name resolution, no access to its shared resources, and the dreaded "Name Not Found" error (among various symptoms).

its ipconfig/release then ipconfig/renew I believe..

so you didn't fix the problem, it resolved it self? great

sorry missed the space out

ip release or ipconfig /release

ip renew or ipconfig /renew

had a hectic weekend and still not recovered

EDit* good work losing_grip
