[SLUG] appaling wireless performance
I've got a D-Link dir-300 flashed with dd-wrt (v24) and my network performance is shocking. If I transfer a file to another machine, scp reports 2 MB per second which steadily drops until I get down to about 200 KB per second at which stage it will vary from 200KB/sec up to about 450KB/sec. If I'm logged into another machine it feels much like a 9600 modem so I assume the latencies are very high as well. iwlist scan reports signal quality is 95/100 and I'm about 1.5 metres from the base station. There are no other networks that I can see that occupy the same channel and there is no other equipment that transmits on the same band. On other networks I can sustain at least 2MB/sec Does anyone have any idea as to what might be going on here or at least where to start looking? rgh -- +61 (0) 410 646 369 [e]: [EMAIL PROTECTED] [im]: [EMAIL PROTECTED] You're worried criminals will continue to penetrate into cyberspace, and I'm worried complexity, poor design and mismanagement will be there to meet them - Marcus Ranum -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] appaling wireless performance
whats network performance like with the dlink firmware? also, whats the noise level at? is there a crappy 2.4ghz cordless phone around?

Re: [SLUG] appaling wireless performance
i think dd-wrt has auto, which will (afaik) make it try to find a clear channel Dean Nima Talebi wrote: You could also see what channel it is operating on, if there are people next door (say you live in a unit), which are using wireless, which is almost certain these days. If say they are on channel 9, you should not be using any channel near that plus/minus 2 or 3, for example you could try 6 or 12. The easier option is just to try a bunch of channels and do a test copy.
