WiFi Signal Is EXTREMELY Weak

kl7919,

Since you said you have to be in the same room as the router, I suspect tghe antenna wire(s) may have come loose. Try the INSTRUCTIONS HERE <ADMIN NOTE: Broken link has been removed from this post by Dell> to see if they're attached.

hi

The laptop is Dell Inspiron N5110 and can't find any wire that come loose.

thank

kl7919,

Can you run an ipconfig /all log and post it back here.

Rick

kl7919,

Try...

Control Panel\All Control Panel Items\Power Options\Create a Power Plan

Select High performance.

Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.

While in the device manager, click on advanced. Look and see if this adapter has antenna diversity. If it does, try changing it from Auto to Aux. Make sure on Maximum power and can you tell me what other setting are listed under advanced.

It have many of possibilities.....first is try checking the wireless card driver in device manager, maybe try reinstalling it.....it may be corrupted.....if this does not solve, try getting a wireless adapter to check, if the wireless adapter have no problem, higher chances is wireless card physically problem, maybe replacing it.....it will some how be costly and time consuming but hope it solve this problem...=D
