Yeah, I know all the technology stuff, I just couldn't figure out if the WHR-HP-G54 had the 125HSM since it's not listed in that section on Buffalo's website. Linksys denotes their SpeedBooster routers with an "S" at the end of the model number, so I was kinda thinking Buffalo might have done the same (so WHR-G54S vs WHR-HP-G54).
Since my WHR-G54S died, I'm thinking about getting the WHR-HP-G54 since it'd be like $2 more off Newegg (Circuit City's price break on the G54S ended and they refunded me instead of letting me exchange).
Thanks, though.
