i believe it is this one: Linksys Wireless-G Broadband Router WRT54G2 Wireless router - EN, Fast EN, IEEE 802.11b, IEEE 802.11g

i couldn't find any other one that looked like what i have. i'm not sure that's what i have or not, but just based off of looks, i'd go with that one. i can verify when i get back home in about 4 hours.

i'm looking at these 3 as possible replacements: Linksys Dual-Band Wireless-N Gigabit Router WRT320N Wireless router - EN, Fast EN, Gigabit EN, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n (draft 2.0)
Linksys Simultaneous Dual-Band Wireless-N Router WRT400N Wireless router - EN, Fast EN, IEEE 802.11b, IEEE 802.11a, IEEE 802.11g, IEEE 802.11n (draft)
Linksys Simultaneous Dual-N Band Wireless Router WRT610N Wireless router - EN, Fast EN, Gigabit EN, IEEE 802.11b, IEEE 802.11a, IEEE 802.11g, IEEE 802.11n (draft)

obviously, that last one's pretty nice. i'm not sure how much better speed i'd get with the other 2 though. middle seemed like it would increase the speed somewhat. didn't really see anything in the first one's description saying it would.
