I've been twiddling with my wireless router settings and nothing I've changed so far has improved performance. Some appeared to degrade it a little.
I'm still only getting 120kbytes/sec in gFTP/SSH. Which translates to about 1Mbit/sec. This is supposed to be a 54Mbit device. Come someone else with a 802.11g wireless network do a little throughput test and let me know what sort of data rate they get.
That sounds about right.
What you need to understand is that the 54Mbit data rate is the absolute maximum under laboratory conditions.
By the time you add protocol overhead, hardware limitations, software limitations and RF propergation limitations the reality is 2Mbits is about the best stream rate there is.
Under "burst" conditions you may get better then 2Mbits but that is assuming perfect RF conditions.
I get 280KB/s using konqueror/fish on my 802.11b. This link goes from my house to my garage/office and the link quality is not good because the garage has steel cladding. I have the access point taped to the window and I have line of sight to it from the kitchen table through an aluminium framed window. This is the only place in the house where it works reliably, even moving to the other side of the table causes it to have problems. Given that my setup is not ideal but I get more than twice your throughput on 802.11b I suspect you should be able to get better than 120Kb/s on your link. Here's what iwconfig says about my card. The link quality goes up and down between 40/92 and 70/92. The 280 Kb/s is what it gets when the link quality is around 60-70. /sbin/iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11-DS ESSID:"WLAN" Nickname:"flap" Mode:Managed Frequency:2.412 GHz Access Point: 00:08:A1:42:9D:BD Bit Rate:11 Mb/s Tx-Power=15 dBm Sensitivity:1/3 Retry min limit:8 RTS thr:off Fragment thr:off Power Management:off Link Quality=66/92 Signal level=-44 dBm Noise level=-148 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:10 Invalid misc:0 Missed beacon:0 -- Glenn Ramsey <glenn(a)componic.co.nz> 07 8627077 http://www.componic.co.nz
