I started the ball rolling on the use of Belkin routers some months ago. I noticed at the time that the Belkin F5D7230-4 and F5F7231-4 routers support WDS (Wireless Distribution System), *PLUS*, they could be had cheap, often $10-20 AR (after rebate), or even FAR (free after rebate). Even picked up a router from Home Depot recently for $25 (price matched to Buy.com), w/ $40 rebate, so I made $15!
The reason this situation is so compelling for use w/ Tivo is a) the routers support WDS, so they can be bridged, b) they're dirt cheap (compared to a dedicated wireless bridge or game adapter, easily $80 or more), and c), support for "G" protocol.
So the basis of discussion in this forum has been to aquire these Belkin routers, configure them as APs (Access Point), and enable bridging. Thus, each Tivo can have its own dedicated AP. All it takes is adding a USB 2.0 ethernet adapter (e.g., D-Link DUB-E100), then patching it to the AP. Because all the wireless configuration lies outside the Tivo, it removes any limitations or restrictions on wireless imposed by Tivo (e.g., "b" only). You just want to make sure you use USB 2.0 ethernet adapters (as opposed to USB 1.1) to get the most bandwidth of the "G" protocol as possible.
There are several configurations possible. Some people use one of the Belkin routers *as* a router, the other routers are reconfigured as AP w/ bridging enabled on all devices. The WDS support makes this possible, something not typically found on competitive brands at this same price level.
In my case, I find the Belkin router, as a router, to be quite limited, doesn't provide all the features I'm come to expect w/ an advanced router, such as that found on my D-Link DI-624. Therefore, I've kept my DI-624 but disabled the wireless, then patched one of the Belkin routers in AP mode (and of course, bridging enabled) to the DI-624 w/ a simple ethernet patch cable. All other Belkin routers are also configured as APs w/ bridging enabled, but all these are patched to my Tivos. Of course, you can do the same thing w/ other network devices, like the family room PC, mom's laptop, whatever you like. IOW, I maintain the advantages of my DI-624 router (which doesn't support WDS, so it's not bridgeable), while gaining the advantages of the Belkin router's wireless WDS.
However you configure it, the "big deal" in this forum regarding the Belkin routers is that they support WDS, can therefore be bridged w/ other Belkin "G" routers (and of course, dedicated Belkin APs), and for a fraction of the cost of buying dedicated APs, game adapters, etc. We're not doing anything here in this forum wrt these Belkin routers that you couldn't accomplish w/ other brand routers, BUT, you would be forced to buy expense, dedicated APs/bridges for this purpose.
In my case, I've managed to aquire four (4) Belkin F5D7230-4 routers for a maybe $20 or so (after all rebates). No way, no how, can you build an equivalent distributed wireless system w/ the "G" protocol this cheaply EXCEPT w/ the Belkin line. As far as the SVEASOFT, some people are using this primarily to make the mediocre Belkin router, a better router. Since WDS is already supported, it doesn't have much more relevance to this discussion. In the case of Linksys, I believe SVEASOFT has *added* WDS support (don't hold me to that, I don't follow SVEASOFT advancements all that closely). In that case, it would obviously benefit the Linksys crowd, it would make Linksys capable of achieving the same thing, although you still can't beat the Belkin on pricing. Just beware that WDS, even when supported, is typically NOT interoperable across brands.
I hope that clears up a few things, it's not really as complex once you see it in action, it's a lot harder to explain than actually execute. It's just that not everyone is aware of the WDS/bridging capability built into the Belkin routers, so people usually don't recognize how easy and cheaply they can dramatically improve their wireless network, and in this case, Tivo specifically.
