The WAG has performed tirelessly once it was set up with my pc properly (running Windows 2000). It seemed to install fine initially, but I subsequently found that connections and downloads from certain sites just could not be made (eg McAfee, Windows Update). After a lot of frustration I contacted the Linksys online help chat facility, and I have to say that their support staff were brilliant (and patient). To cut a long story short it appeared that the firmware needed to be updated (WHY???? - it was brand new out of the box and I've had Windows 2000 for 6 years!!) Further problems then ensued, requiring the router to be configured separately by my laptop (Windows Vista) and my old modem. This was infuriating, not because of any technical difficulty as such, but because the setup was now relying on external hardware which many other people in a similar predicament may well not have available. The other observation made then and subsequently was that it takes forever to reboot and re-establish the DSL and internet connection. If you don't have patience with this then you could be tempted to start switching things off, press reset buttons etc. DON'T for at least 15 minutes (seriously!). By the way, the help person's reset procedure was different to the instruction manual's....
Somehow I've just managed to lose the updated firmware by mistake whilst trying to connect a wireless printer (which didn't work wirelessly) - I don't know how (reset button?) and was only able to connect the laptop and other 2 pcs again after going through the firmware update procedure again, as suggested by another helpful Linksys person, and setting everything up from scratch. The paperwork doesn't mention this drawback if you press reset...
So - the product has performed seamlessly, with good range inside and outside. But blimey -what a pain in the posterior to get there. I feel the helpdesk staff are also being seriously let down by poor product documentation to the user, with conflicting procedures and insufficient troubleshooting detail. To ship the product with effectively a useless firmware makes it unfit for purpose (how do you update it if you can't make the internet connection in the first place?), and the source of that is bad management.
