Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

Slow Wireless Speeds

fletch · 2005-07-17 14:40:49

I am copying over a few files from my laptop to my PC using Wireless. The laptop has an 802.11b card so I would expect it to achieve speeds of 11Mbps. However when I use Windows Task Manager, it maxes out at about 40% of it's potential!? Anybody know why this is? I am using a Netopia 3347WG router (provided by Eircom)

For crying out loud you NEVER get the theoretical speeds what with overheads.

Due to the CSMA/CA protocol overhead, in practice the maximum 802.11b throughput that an application can achieve is about 5.9 Mbit/s over TCP and 7.1 Mbit/s over UDP.

Any fool of the street can tell you this stuff fletch :rolleyes:

lol....thank you for that very gracious reply Offler! I would't expect to attain the maximum 11Mbps but 4.4Mbps seems pathetic

Sounds like close to maximum throughput to me fletch. Wireless has massive overheads. Throughput of 50% would be in perfect conditions.
