USB wireless adapter crashes while copying files from another computer

[buras12]

Hi folks,

I am running a freshly built Win7 x64 desktop. Bought a Netgear wnda3100v2 wireless adapter to connect to my router (asus rt-n56u). The connection runs fine most of the time - web access is OK, same with accessing a shared HDD connected directly to the router. But when i try copying files from another Home group machine (win7 ultimate DELL Inspiron laptop), network connection immediately dies altogether - i need to remove the adapter and plug it back in to resume network connection. There are no problems accessing the files, it's the copying that is broken.
I tried using both Netgear native drivers and these - same results.
Couple of questions:
- Why is there such a weird connection loss?
- I guess i will return the adapter to amazon.com. Any suggestion for a more reliable dual-band adapter?

Thanks, David

HI David

It might not be the adapter. It might be Homegroup and IPv6. One way to check is to create a new network connection using "workgroup" (it uses IPv4).

If this workaround works you can disable IPv6 and kill homegroup.

IPv6 has connectiv ity issues on SOME systems (especially legacy systems)

Thanks for the response. Could you suggest how to actually do this? I have no experience setting up a workgroup.

Just set up a workgroup, but there is no change.

Figured out the issue with the adapter

After some tinkering i understood that the adapter does not "speak" to other machines that are connected to 5 GHZ WIFI network. Once i switch them to 2.4 GHZ, the problems disappear. The Netgear adapter itself is at the 5 GHZ network. It is now certainly going back. If i only knew what to get instead...
