I am having lots of problems with the Win7 Homegroup feature which requires IPv6. I have an access point attached to the 4000 with three laptops connected through that and a wired desktop connected directly to the 4000. Homegroup seems to be stable when only the laptops join the Homegroup. When the desktop joins things start to get flaky. The usual problem is that not all Homegroup members can see each other and the combinations of which can see which change. I have installed all the latest updates, firmware and drivers. I have searched the Internet extensively for clues and I found some suggesting router issues, although no mention of the RVS4000. Does anyone have any experience with IPv6 and the 4000? Does anyone have any experience with Win7 Homegroups and the 4000? Any suggestions to find the problem?
Some good comments on IPv6.
For IPv6 Internet access, you will likely need to use one of the free tunnel brokers and configure your local router to tunnel and route all traffic to the tunnel broker.
Not something Homegroups is meant to provide.
Homegroups is a local only sharing service between PCs. Domain controllers can join and see / access the other resources, but other PCs will not see the domain controller or be able to access the shares via Homegroups. At least this is how it is supposed to work. We would not want Homegroups to break all of our security ...
Below are some links that might help. The first is one shows the wireless modem is suspect, but Microsoft thinks it is really a firewall or IPv6 problem.
This second link is for when IPv6 is not working properly.
Homegroups does not need anything from our router since it is using only link local addressing. It does not require or have any knowledge of IPv6 global addressing, no worries from the router and no real reason to enable IPv6.
If you have 'islands' of IPv6 at your separate offices, then you might want to enable dual stack and create a tunnel between sites. This does not sound like what you are asking.
Do please check these links and let us know! Kindest regards and I hope this helps,
