The first-level support folks at Qwest didn't have any idea what I was talking about when I asked about this; maybe somebody here knows something.
I have an Actiontec GT701-WG DSL router. I downloaded (from Qwest's Web site) and installed firmware release QW05-3.60.3.0.7.5 a few months ago. Checking the Web site a couple of days ago, I found that they'd reverted to level QW04-3.60.2.0.6.3.
Other than some cosmetic changes on the Web interface, I didn't notice anything different in the QW05... version, and it's been working OK for me.
Anybody aware of any specific problems or issues that would have caused Qwest to move back to the older level?
