I wouldn't have the patience to do something like that... I'd just grab a 802.11n wireless router and be happy, even if there's a slight speed penalty for it...
Some routers do funky things. I can't properly port forward mine. It always says I'm firewalled when using wifi (even with opened ports setup) but as soon as i pull a land line into my laptop, no problems. I can't figure out what's going on for this. So I just use land lines when at home.
(Land line= network cable)
Yeah, that's true. It seems like wireless routers are very hit or miss - they either work incredibly well or they don't work at all.
I've been using an Airport Base Station (802.11g) for the past 4 or 5 years, and it's always worked very very well regardless of whether cordless phones, microwaves, etc. were in use or not. Its signal is always strong, and getting dropped is a truly rare thing.
Linksys, on the other hand... *shudders* I owned a Linksys wireless router and the thing sucked so hard it wasn't even funny. It's a pain to set up, and after I got it set up, its signal was weak, it was constantly crashing and rebooting, devices interfered with it something fierce, etc, etc. At first I thought I just got a bad unit, but my friend bought one and he had the exact same results. I will never buy one of their products again.
I had a Netgear router for a little while, and it worked well for the year and a half or two years before it just randomly died... It got awfully hot though, so the heat may have killed it.
Another thing that makes me hate hardwired networks is the fact that it makes moving your computer to a different area of the room or to another room a real pain, unless you wired an ethernet socket into every room in the house (sans bathrooms of course).
