Ok , it should surely be the WRT54GL , because the WAG54G only has one areal and the others similar boxes lack either the antennas or the lighted button on the left side of the display or both.
The one on the linsys site however lacks tha tacky lime green/corn blue stcker shouting "Speed Booster!!!", and moreover the one on the linksys site is listed at 90$ and I paid it 120 Euros.
Every time I check ot the new routers, particoularly the simultaneus dual bands models I feel tempted to upgrade also because I also have a lynksys NAS and a Linksys media extender/dvd player (even if now the 60" plasma screen to which this media extender is connected, is also wired via HDMI to a networked , top notch HTPC, so it's used basically only as dvd player if ever)
However my reasonable half (or maybe 1/5) keeps telling me that a router should only work well, and in more than an year that this thing has been working non stop 24/7 it never once gave me a single reason to complain about anything; which apparently is pretty exceptional for those things, and since the Hero seems to love it too, for the time being I'm gonna fight off this silly temptation.
