Hello, Satcomer -
No real news - MacBook worked fine on another network with a slightly newer Netgear router (1 digit up in the 'v'). I tried taking that router back here to the house, plugged it in, still had slooooooowww access. Temp solution is to put old Airport Base Station as the primary wifi router here at the house. It isn't fast (might be 802.11b) but at least spouse's MB seems to be working just about normally. I had read one post on this site about possible conflicts when a modem (cable, in our case) has two wifi networks running off of it. But even then - with the Netgear as the first in line (cat5 cable from Netgear brought signal to outbuilding where Airport was hooked up) the Airport gave reliable pretty-near-normal internet access when that network was selected (not so good signal back here at the house from it, of course). The Airport doesn't have any other ethernet plugs for connecting cable to send signal out to barn, so I've got to try finding a connection solution. I guess I could pay another 50 - 60 dollars for a newer wifi router, but hey, 50 - 60 bucks - there are other places where that's needed these days.
