Weak signal


I have recently purchased a VAIO E-Series, and although I am very happy with the computer itself, it turns out it has a very weak wifi-signal pickup. I have had no problems with my router with computers in the past, and I also have the up to date driver for the wireless adapter.

I currently have the Atheros AR9485WB-EG Wireless Network Adapter inside my computer, and I was wondering if anyone else has this problem.

I barely get 4/5 bars of connection when 10 ft from the router, and I get zero connection in my bedroom. I have changed the channel on my router (even though I didn't need to, since the next closest house is a hundred yards away.)

If anyone can get back to me on this, it would be great! Thanks!

Re: Weak signal

Hello and welcome the Users Discussion Forum.

It looks like that you might be experiencing wireless interference on your system with the location of your router. Interference from a 2.4 GHz or 5 GHz telephone may cause connection issues when using a 802.11a, 802.11b, 802.11g, or 802.11n wireless network (WLAN). These wireless standards use the same frequencies. Other wireless devices such as Bluetooth® devices, baby monitors, garage door openers, microwave ovens or wireless toys may cause interference. Also, large power transmission lines or metal surfaces such as walls or desks may interfere. The connection issues may include pauses, disruptions or other erratic behavior with the wireless network.

The following are some suggestions that may resolve the issue:

1. Change the location of the wireless router or the base station of the cordless phone.
2. Change the channel used by the wireless router.

For information on changing the channel of a wireless router or access point consult the manual included with the device or contact the manufacturer directly.
Many 2.4 GHz and 5 GHz cordless telephones operate with what is called frequency hopping technology. This technology utilizes the entire frequency range also used by 802.11a, 802.11b, 802.11g and 802.11n wireless devices. Thus changing the channel of the wireless router may not eliminate the interference problem.
Operate the phone with the antenna lowered if that option is available.
Use a cordless phone that operates on a frequency other than 2.4 GHz.
Limited the use of Bluetooth devices or turn off the Bluetooth adapter in the computer.
