Computer :- 64 bit Win 7 SP1, fully patched, ASUS M4N68T-M motherboard, AMD Athlon 2 x2 250 3.0GHz processor, 4 Gb RAM

My ISP recently gave me a new 802.11 g/n router, my wife's laptop is g/n capable, so to take full advantage of the n capability I bought a Netgear N150 USB adapter ( Model WNA 1100 )to use with my desktop, which comes with an installation CD. I picked this adapter, from my local Maplins, because it specifically listed Win 7 on the box.


I switched off my computer, unplugged my b/g Sitecom adapter, re-booted and put the CD in and followed the on-screen instructions upto the point where I was told to insert the adapter. It then came up with a sub-screen saying 'Detecting adapter ...' and hung there. I uninstalled the software and tried again, with exactly the same result, except that this time I left it while I went down to the local supermarket for the shopping. It was still detecting the adapter when I got back 45 minutes later !

I took it back to Maplins who exchanged it without question for another, and tried again, with the same result. I then got the newest driver from the Netgear web-site, same result. Trouble shooting on the Netgear site suggested trying installing it on another computer. I installed on an old laptop running XP SP3 and it went straight in off the CD and connected flawlessly to my router and the internet - so the adapter works.

I have since been in contact with Netgear's on-line assistance and they have made various suggestions :- disable A/V and firewall, reduce the amount of RAM (?), use the latest driver - but it still hangs at the 'Detecting adapter' screen. I have been uninstalling the software between each installation attempt.

So far, every time I run the installer, the software installs, I am asked to insert the adapter, the Windows messages 'Found new hardware' and 'Your new hardware installed successfully' appear, the installer screen switches to 'Detecting adapter' and just hangs. The little blue LED on the adapter doesn't light at all, yet when I switch back to my b/g Sitecm adapter it works perfectly in the same USB socket.

Anybody got any ideas ?

It might be WIn 7 not compatible with the product. Check online for issues or probable solution on the netgear adapter such as this http://forum1.netgear.com/showthread.php?t=50346

Thanks jhayz,

I followed your references up, but they didn't take me much further. Most of the problems under discussion appeared to be involved with earlier drivers and software remaining on the system and causing conflicts which prevent the new adapter working. As far as I can tell, if I disable the b/g Sitecom adapter I am using at the moment, then there is nothing left to conflict with any new driver and software. The old laptop I tested the N150 / WNA1100 adapter on still had the drivers for another Sitecom adapter and the manufacturer's Atheros drivers still installed, and the N150 installed straight off the CD and into action with no problems. ( The reason the Sitecom drivers are on the laptop is that the OEM wireless unit failed )

I am at the moment still waltzing around the doors with Netgear's support, but they are beginning to repeat themselves. I suspect that it is a Netgear software / 64bit Win 7 compatibility issue, and the probable answer is to wait for another version of the drivers to appear. This is annoying, but even if I was to write off the 14.99 the adapter cost me, it wouldn't cause bankruptcy ! The biggest annoyance is that I have probably spent about 4 hours trying to get this to work, a job that should have taken about 5 minutes tops, and I have better things to do with my time. I am going to be away for most of the next three weeks. I may, or may not, renew the struggle when I return. Anyway, Happy New Year !

Regards,

Chris Cosgrove :P
