Only one computer can be connected via wifi to the router

Ok my friend has a problem with her router. If i was there i'd be able to better troubleshoot this issue but since i am not i cannot.

The issue is that only one computer can be connected to the Lynksys router at one time via Wifi. I don't get why this is happening but it somehow is. I believe it is a WRT120N if not it looks very similar to it. It's been a little while since i've seen it. I'll get theofficial make and such later once i can get her to look at it.

The router is set to the default settings everything is set to default and is connected to a 1.5Mb/s DSL modem(router whatever you wish to call it). The Two laptops are Vista (laptop not sure make and model), and a Neo Laptop(seems to be a clevo reseller) running windows XP SP3. Now i don't understand why Vista and XP would have issues being on the same wireless network but it does seem so.

Any help on this issue will be greatly appreciated.

 

two throughts

she has somehow defined the scope of the ip range to two ip addresses

she disabled dhcp and is getting an address straight from the dsl modem

 

hmm i'll have to have her check on the dhcp thing. I thought that may be one of the causes but her father's currently doing his work right now on the wifi so she can't obviously check things yet.

 

well xp and vista do give problem while networking
you should assign ip addresses yourself and not use automatically assigned ip addresses.assign ip in the same range jst change the last digit of ip eg.
give ip's like 191.168.1.2, 191.168.1.3 and it will work
have done it myself too.

 

they are not technically "networking" in that they are not trying to get the two machines to talk with each other--just talk with the router.

So XP and Vista being on the network together doesn't enter into it.

 

well i understand what u mean but for the router they should have the same default gateway in this way they can form a wlan network.

 

My only point was that the problem is not that there is a mixed OS network--not that they are not sharing a gateway.

Actually, though, there is a connection I hadn't thought about. When the second computer enters the "network" they are still having an election to choose a browser master.

Shouldn't be the cause for this problem, though

 

wel i had her look at it and DHCP's workign just fine it seems. Also the ip range is 50 ip addresses the only strange thing is when typing ipconfig/all it showed the wireless info plus the dsl router somehow. The IP adress assigned for the computer on it first was 192.168.1.1

So what's the best suggestion to try to fix this puzzling phenomenon

 

Is this DSL router also support Wireless Access? Just like you mentioned, it is probably that this is the issue, the DSL modem/router only works with ONE wifi connection as at time.

cheers ...

 

192.168.1.1 is the default ip address for the router...if the computer is getting it, something is definitely wrong. How did she connect to the router to check the ip range if the pc has the router ip address.

We need the dsl model, router model (for sure). I think ultimately you need to put the dsl modem in bridge mode and let the router handle the connection

 

... she was connected to the wireless router w/o being actually connected to the internet which she checked it. The ipconfig/all i had her do was wireless. So how can i make it go into bridge mode? And i doubt i'll be able to get the exact name and make of the router. I'll probably have her try to change the ip adress on it but the main thing is they have to manually the dial the connection each time anyone wants to get onto th wireless. the isp i think is a complete idiot for saying they couldn't fix it considering it didn't used to do that.

 

Without knowing exactly the set-up and connection between the DSL modem/router (and Model) and the LinkSys router, I think that we will all be grasping for air here

cheers ...

 

The ISP can tell her how to put the modem into bridge mode, but as qhn notes, we need to know the exact make and model of the router to tell you how to set it up for pppoe so the router dials on whenever a user needs the internet

 

I don't get why they have to manually dial the connection each time. The router should the one be doing that.... You can also try using a ethernet cable to try the LAN connection instead of WAN....
Also check the domain name... they should all be THE SAME for all laptops trying to connect with the router and internet.
