I've got a Buffalo WBR2-G54S after a recommendation for Buffalo stuff by Peter. It has worked well for years. There's a similar box on eBay (WLA-G54) for $20 but it doesn't have the power brick. (I don't know anything about the differences between the two models.)
But before buying another box, you might want to try a different firmware version for your FVS114. There's a thread at DSLReports that talks about similar issues, with some users reporting success with different firmware. http://www.dslreport...ashing-constantly
FW version 1.1_15 is available at the Netgear site - http://kb.netgear.co...s/model/a_id/2419 - I dunno whether that's actually better than any of the other versions.
HTH a little. Good luck!
Cheers,
Scott.
