limited to no connectivity, wireless problems

hey im having trouble with my wireless network. it works fine during the day which i can only guess is because my laptop is the only computer on the network (the other people who are on the network are usually on later). Then is when the problems start. My dad and my sister are both on the network. When they are connected, I get disconnected. Usually the error message is the "limited to no connectivity" basically saying that I'm "on" the network but i can't use it (i think?)

any thoughts on this? it's getting really really annoying and the tech guy that normally comes to my house doesn't really know what hes doing. I can provide screenshots, more info, or anything thats needed to help figure this out.

thanks, ross

 

Some helpful information would be router model and current configuration. Limited or no connectivity usually occurs whenever your computer is not obtaining a valid ip address from the network. I don't know what OS you are using so we can go the command prompt route which will work with xp and vista.
Start->Programs->Accessories->Command Prompt

In the command line we are going to need to type ipconfig/all
Then were are going to be looking for either: Wireless LAN adapter Wireless Network Connection(Windows Vista) or Ethernet Adapter Wireless Network Connection(Windows XP) and look for IP Address:.....
If it has a 169.254.xxx.xxx number then that is the cause of the limited or no connectivity message.
However, unless there were any configuration changes, if you are pulling in an ip address then it should resemble a 192.168.0.xxx or 192.168.1.xxx number.
Is the problem caused only when both your dad and your sister are on the network? If just one of them is connected are you able to connect? Does the router have any parental controls that only allow users usage during certain time frames?
Another possibility(highly unlikely though) is that someone configured the router to only give out several dhcp leases and they are all being used at night. I really don't think that would be the problem, but it could be a possibility.

 

Sounds like your running mixed mode.

A lot of routers have problems running mixed mode. So say you're running G, your sister is running G, and your dad on his older laptop is running B. Well when he connects he converts the entire wireless network to B.

I have the exact same issue with my buddies older laptop when he come over. I have a G router, my wife and I's laptop use N cards. We never have a problem connecting. As soon as he connects he kicks us both off even though the router is set for mixed mode.

I heard a work around is to remove the mixed mode. Have your router run only in B mode, or G mode, whatever matches your card. Then see if it happens again. Chances are your dad will come back to you and ask why he can't connect to the internet.

A more permanent solution would be to have everyone use the same type of network card (all G's or all N's), or buy a router that doesn't have an issue dealing with mix mode.

 

Sounds to me like ur wireless router is set to distribute no more than two IP Addresses. You may want to log into ur router's config. page via ur web browser and take a look at its configuration. Mostly so the DHCP range!

To access the router's config. page u will need to know its IP address...Go to Start-->Run and type cmd then hit enter. Now type ipconfig /all and take note of the default gateway. Do this with any laptop that has Internet connectivity at the time or else it wouldn't be correct info.

Then use that default gateway by entering it in ur web browsers' address field...for ex. 192.168.1.1 and hit enter. Log in and check out it's configuration; especially the DHCP range settings.

BTW what router are u using? brand/model #

 

I have a compaq presario v6000, what wireless card do i need?

 

What happens if you try setting up a fixed ip address?

 

You can force the DHCP settings, you will need to copy all the information from a computer which connects to the internet to the other one which is not connecting.
