Got a new laptop and it keeps disconnecting from wireless network. Pretty sure it is not a hardware problem. Machine runs Windows 7. Can't see any real difference between the setup from the other laptop except no v6/local access but there doesn't seem to be any way of changing that. The Norton firewall has lots of reports of sensing new IP addresses. I'm stumped. Any ideas how to fix?

Some routers and Win 7 can be bothersome. If the router has a b/g/n option try reconfiguring the router to just b/g and set the wireless card on the laptop to the same. Or reconfig the wireless on the laptop to use just 'g'. It will stop jumping around frequencies.
Can you let us know if this helps. Thanks

Keeps disconnecting ?
How frequently ?
How long does it stay connected ?
Ignore the suggestions to delete things for the moment while you investigate the cause.
The question about router may be relevant in this case. Does your router support n ?
(If it's a junk ISP router thens odds are the answer is no)

The question about the router is relevant. Wireless instability due to band hopping is fairly well documented.
If the device is using win 7 then it is safe to assume that the wireless card is 'n' compatible. If the router is only 'b/g' compatible then the wireless card should be reconfigured to use just 'b/g' this will remove the instability.
I cannot be bothered writing a technical paper on the reasons behind stability issue but there are recognised issues of using the 'n' standard in a mixed wireless environment, 'n' is great in a pure 'n' network, factor in encryption issues (WPA 2 with 'n' or take a 60% performance hit), cross channel interference due to co-location and mixing the 2.4 and the 5 ghz bands the issues surrounding stability within mixed wireless environments are in their infancy.

If it's not an n supporting router it won't be band hopping.
Might help to list the make and model of both the laptop and router especially as one or the other
may have a record of problems in this area

Despite the network issues, do this anyway. For the greater good.
POS?
It's strange as Norton is nearly always highly rated in product tests, and I've frequently been suckered into installing it, to be hugely disappointed every time.
