No worries, I'll post on the list once testing complete.

Which I'm aware of. But, can I reduce the effects by increasing the transmission rate of WDS? Before running at 24MB transmission rate with a 3MB internet bandwidth, I *could* get roughly 2.5-3MB at the last hop. So therefore getting 50% reduction in transmission rate, and not 50% reduction in internet bandwidth. Does that make sense? So running a WRT54GS for example at a higher reliable transmission rate (afterburner/speedboost) in WDS mode. This would reduce transmission rate by 50%, but if it's higher than 36MB then surely I'll receive less of a hit in internet bandwidth drop (from a total of ~9MB)? This is only theory as in testing between 24MB and 36MB transmission rate, I got a higher internet bandwidth on the last hop when running 36MB transmission rate. An answer I'm trying to find. I don't really want to go out and buy 2x WRT54GS to find I can't get a higher transmission rate using WDS than I'm running now, which would result in a waste purchase. Just hoping someone would know, or someone could lend me 2x WRT54GS (or similiar afterburner supported models?) to test the theory :) Regards Andy :) From jgxhs at nessie.mcc.ac.uk Thu Feb 1 23:18:10 2007 From: jgxhs at nessie.mcc.ac.uk (jgxhs at nessie.mcc.ac.uk) Date: Thu, 01 Feb 2007 23:18:10 +0000 Subject: [manchesterwireless] Linksys WRT54G and WDS mode In-Reply-To: <001601c745eb$970cad50$4b7018ac@wla.int> References: <002c01c7454a$8629a0c0$4b7018ac@wla.int> <001601c745eb$970cad50$4b7018ac@wla.int> Message-ID: <95t4s29306sdfg4nm4faqrshlait0piq5k@4ax.com> the 50% reduction applies to the wifi link,, so ,, so long as you have a significantly higher wifi link than your ISP link then it should not be too important.
