For small home networks and broadband such as DSL and/or Cable, Linksys works. However, i recently moved into an apartment that has T3 and the Linksys simply could not handle the bandwidth. Either that or the card and cables went bad. We tested it all out and the long and short of it is that I had to change the cards and cables (cables came with the Linksys NICs).
I now have Intel and man what a difference. I bought the 8 port Intel HUB (10/100) and all Intel NICs. SOLID, is all i have to say.
I also recall having to exchange a bad Linksys NIC when i first bought the Linksys Network Kit. Personaly, if it says 10/100 and then it can't handle a 45mb connection, well, then it aint worth crap. IMO, i'd stay away from Linksys and Netgear (heard of similar problems, but no personal experience with them) and pay a little more for the stability. I have no colissions with the Intel, collisions were the norm with the Linksys. enough said i guess.
you must choose, but choose wisely
