Wireless router slows connection
in [Wireless Internet]
|
From: Jim on 2 Apr 2007 09:14 I am using a WRT54G router on a cable connection. If I understand correctly, the fact that I have it set for WPA PSK is what slows down the connection. Example while wired my download speed is over 7mbps while operating wireless it is 1 to 1.5. Short of turning off security is there any other way to boost the speed? Jim

Throw $60 at a new one? What hardware version do you have there? -- Todd H. http://www.toddh.net/

WPA PSK will slow down the MAXIMUM wireless speed by about 10-15% due to CPU load. You probably won't see it. Turn of encryption temporarily and run your benchmark again to compare to check. What is your wireless connection speed as displayed on your wireless client? Your wireless thruput should be about half the connected speed. If there's interference, even less. 1Mbit/sec thruput means lots of interference or a fairly weak signal. I'm not sure what to recommend because I have little clue as to what you have to work with. If the wireless client is portable (i.e. laptop), drag it into the same room as the WRT54G and see what it can do under ideal conditions. If that works properly, then work on improving the wireless signal (i.e. aftermarket antennas). -- Jeff Liebermann jeffl(a)comix.santa-cruz.ca.us 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

Signal strength shows excellent at 54 mbps. I have been using this setup for over a year now and it has always been this way and I have not figured it out. SSID broadcasting is turned off and I have MAC filtering. I have changed those settings and found no difference in performance. If it didn't involve too much work I would arrange to run this wired most of the time. As it is I am only occasionally downloading large files. WRT54G v 3.1 Firmware 4.20.7. I have upgraded the firmware once and don't know if there is an update but that did nothing either. Does this information provide any ideas.

What happens to your speed when you turn off all security?

Signal >strength shows excellent at 54 mbps. That will only be meaningful when the wireless is under load. Run a speed test, and see if the reported wireless speed changes during the test. And move the wireless client to about 6 feet from the wireless access point to see if that makes any difference. >I have been using this setup for over a >year now and it has always been this way and I have not figured it out. SSID >broadcasting is turned off and I have MAC filtering. I have changed those >settings and found no difference in performance. Leave them off: * SSID hiding doesn't really hide anything, and can make it more likely that neighbors will try to use the same channel. * MAC filtering is too easily spoofed to be of any real value. * Both often cause problems. >If it didn't involve too much work I would arrange to run this wired most of >the time. As it is I am only occasionally downloading large files. Radio frequency interference is the most likely problem.
