Today I upgraded from 1.44 to 1.45.7.

TFTP from XP didn't complete the first time. Re-ran and it updated OK. All settings lost. Found Internet traffic sluggish but moving along in XP. Later discovered that I couldn't download files - they'd stop part way.

Using OS X 10.2.8, I could not get to any web sites from Safari - timeouts. Could not get to Software Update either. Ping worked fine. PowerBook worked fine earlier in the day at Starbucks.

I downgraded to 1.44.2z and these problems have vanished. Settings needed to be re-entered again.

Version 1.45.7 didn't work for me - your mileage may vary. Otherwise my Linksys router has been good to me.
