Wireless range extender interference

Postby jackdemcak » Sun Mar 14, 2010 11:46 am

My SoundBridge Radio sits next to my Linksys WRT600n Wireless router. It gets signal level readings of -20 dBm and plays flawlessly.

I have a PC about 50 ft from the wireless router. It gets a very low wireless signal. Yesterday I installed a LinkSys WRE54G Range Extender and placed it near the remote PC.

The SoundBridge radio is now reports signal levels in the -80 dBm range has frequent episodes of rebuffering. When I disconnect the range extender while the radio is playing, the radio displays the "Connecting to station ..." message for several seconds and then reconnects at the -20 dBm level.

I believe that when the range extender is operating, the radio connects to the extender's weaker signal, even though there is a strong signal available only a few inches away. Has anyone run into this problem and solved it?

This is actually quite normal behavior of a Range Extender. Range Extenders work off of the idea of pulling a signal from the Base Station and then repeating the signal frequently, this generally causes rebuffering issues with most wireless devices within a network.

Your best bet for increasing the range of your network while still keeping good network speed would be to add a wireless access point to your network.

Thank you DerekHelps. From what I have been able to learn, the problem is deeply seated in wave theory, nodes, and reflections. Consequently, your advice to use access point makes a lot of sense.

I did try my luck one with last configuration, however. I moved the range extender to a position 15 feet beyond the PC that was receiving a very low wireless signal. This put the range extender about 40 - 45 feet from the wireless router. The PC's wireless signal strength increased by a factor of 3 achieving a solid 54 mbs data rate.

My Roku radio did not pick up the extender's signal (maybe it was too weak to detect?) and locked in on the strong signal being emitted by the router. This may be an example of the adage -- better lucky than good.

Thank you for the explanation! I didn't know that this is the normal generic levitra behaviour as well and was always wondering....
