I upgraded my home network, replacing a LinkSys BEFW11S4 with a new WRT54GS. Laptop cards for the family laptops were also upgraded to WPC54GS cards.
I have Verizon DSL, with 1.5Mbit provisioned.
With my old BEFW11S4, I would consistently get 1.2-1.3Mbit down on speed tests.
With the new WRT54GS, I taking a huge regression - 200k - 400k down, at best. Download speed is 4X-6C slower.
I do not have security enabled.
I'm basically using default settings - same settings I had on the BEF11S4.
LinkSys (tech support via email) suggested I change RTS Threshold to2304 (from 2432) and Fragementation Threshold to 2304 (from 2346). They also suggested I change DTIM from 1 to 3.
My limited knowledge of what these advanced wireless settings do leave me very skeptical as to whether or not they'll fix a 6X bandwidth regression, but I will try them and post the results (right now, I'm back on the BEFW11S4, until my kids tell me it's OK to take the network down :^).
I'm open to the possibility there's something wrong with the WRT54GS, and if (when) the LinkSys suggestions do not fix the problem, I will exchange it for a new one.
Just a heads up on an odd problem doing a simple (and otherwise painless) upgrade of the home LAN from 'b' to 'g'.
I will post findings, results.
