From: Linea Recta on 1 Apr 2008 15:58 I installed a wireless router SITECOM WL-174 (54 Mbps!) which is connected by wire to PC (fast ethernet), and wireless to a laptop. Internet access from all computers works OK. Today I made connections for transfer to & from the computers directly (shared folders). This also seems to work, but I was disappointed about the speed. A 1 GB test file was transferred with a speed of about 2 Mbps. What can be done to increase speed? PC has Windows2000SP4 Laptop has Vista Signal strength = max. -- regards, |\ /| | \/ |@rk \../ \/os
From: Jack (MVP-Networking). on 1 Apr 2008 16:14 Hi It is probably the speed that your Wireless is functionally providing. 802.11g when the Wireless client is few feet away from the source and there is No electrical interferences should provide 14 to 20 Mb/sec. Try to change the Wireless channel and optimize both computers TCP/IP stack. Optimizing the TCP/IP Stack - http://www.ezlan.net/Internet_Speed.html Otherwise, keep a spare network cable plug the laptop to the Router and use it when large file transfer are needed.

Yes, that's what I thought, so I'm not getting anywhere near those values. :-( At the time of testing the wireless distance is about 1.5 meters and signal strength is max. > Try to change the Wireless channel and optimize both computers TCP/IP stack. > Optimizing the TCP/IP Stack - http://www.ezlan.net/Internet_Speed.html > Otherwise, keep a spare network cable plug the laptop to the Router and use > it when large file transfer are needed. > Jack (MVP-Networking). The internet speed is OK: 321.8 KByte/sec down and 31.3 KByte/sec up. These values are the same wireless and wired. They are restricted maxima by my provider. But I had a problem with the (wireless) inter-computer speed... No solution to that? -- regards, |\ /| | \/ |@rk \../ \/os
From: Jack (MVP-Networking). on 1 Apr 2008 17:51 Hi Optimizing the TCP/IP according to the Internet might increase the local transfer too since it probably would increase the RCwin.

Both Vista and XP have known performance issues with copying large files (MS claims that SP1 fixed this... ) By the way, most of XP registry tweaks for tcpip behavior won't work on Vista.
