I even do pre-configurations for some applications. <snip> May I ask<g>............Does the WRT54GL support current standard DOCSIS 2.0 and/or newer ???? (ThankYou in Advance!) The WRT54GL v1.1 should overclock to about 250MHz (see http://www.dd-wrt.com/phpBB2/viewtopic.php?t=38179&highlight=docsis and http://www.dd-wrt.com/wiki/index.php/Linksys_WRT54G/GL/GS/GX#Clock_Speed_and_Overclocking - pardon my lack of tinyurls for these; some people have been reticent to use them due to security concerns). That said, per the first link, about the best broadband performance you're likely to see with the device is somewhere around 50Mbps. Even the factory firmware will only get you to around 70Mbps or so. The newer models seem to do a bit better (WRT600 & WRT350N reportedly will handle about 160Mbps (must have gig NICs in those units), and the Dlink DIR 855 supposedly does 330Mbps (see th second page of the forum link, above). Again, all of this is anecdotal evidence to me, as I have no firsthand experience with these models or even with pushing the WAN port on the WRT54G series... Of course, all of this ga-ga stuff over WAN bandwidth is quite amusing to those of us running servers, as your real broadband performance is directly dependent upon what's on the far end of your link. Here, for example, I have about 12Mbps coming down and 4Mbps going up (let me test...yep, that's right about on the money). And remember, that the 4Mbps will get saturated pretty quickly depending upon how many people are connected to the servers over here, so even the big boys like youtube, facebook, twitter, ebay, etc., will likely take some time to get to the point where they can actually deliver 100Mbps to multiple clients (at least, that's my best guess; I have no stats, though speculation on this abounds - try googling, for example, "youtube bandwidth"). I have a couple clients with T1's in the office. Now, when you're at home by yourself, 1.544Mbps of clear, point-to-point signal is amazingly crisp. However, in an office of 35 people, with a dozen site-to-site VPN connections coming in, and running a mail server, all it takes is for some inconsiderate so-and-so to start streaming radio or (g-d forbid - well, I forbid it!) video, and 1.544Mbps quickly drops off to about 400Kbps down to 300Kbps down to...well, you get the picture. Bandwidth is often a matter of perception. :-) <snip> -- Lewis ------------------------------------------------------------- Lewis G Rosenthal, CNA, CLP, CLE Rosenthal & Rosenthal, LLC www.2rosenthals.com Need a managed Wi-Fi hotspot? www.hautspot.com Secure, stable, operating system www.ecomstation.com -------------------------------------------------------------
