Windows 7: Issue with Homegroup and WPA2 security

Issue with Homegroup and WPA2 security

Hi all have an issue with WPA2 security.

I have always run my wireless network using WEP security and never had any issue at all.
I recently changed the profile to WPA2 Personal as I was told this would improve network security. Updated the settings on all network items (PS3, Wii, 2 x XP laptops, a linux netbook and my sons PC running W7), and all worked fine.

All able to connect to the internet, nero media server working on the PS3 and homegroup working fine on the 2 window 7 pc's.

I then reboot my PC (The main PC, wired to router) and no computers detected in the homegroup, the PS3 cant see any media servers, either windows or nero!!

So I switch off wireless security, and all is good again.
Switch back to WPA2 and everything works.
Reboot my pc and the whole lot goes again!!
All PCs and PS3 etc have full internet access whatever the security setting and filesharing between the 2 XP laptops is unaffected.

It seems to be a conflict between Homegroup and wpa2 security.

Any ideas??

My router is a Linksys wag160n

It's definitely something in the setup that's causing this.

Do you have UPnP enabled on the router? And have you set all machines and devices to AES encryption?

Hi, thanks for the reply.
UPnp is set up on router.
WPA2 mode is TKIP or AES (Can not select just 1)
Manually configured the wireless settings on the PS3 and the other W7 pc to ensure they were both on AES.

Have rebooted the main PC and the settings seem to have held!!, homegroup working and PS3 picking up media servers.

Off to google TKIP vs AES to understand why that would cause an issue.
Hopefully it's fixed, or its back to WEP!

AES and TKIP are encryption types. AES is much more secure and virtually unbreakable. It's used by governments. All machines and devices must use the same encryption standard.

Sounds like it's fixed to me.

New router and effect of changing security setting from WPA to WPA2
I am planning on upgrading our LinkSys WRT54G2 to a new router, probably the Netgear Nighthawk AC R7000. When I do so, I plan to also upgrade our present WiFi security from WPA to the Nighthawk's default, WPA2-PSK (AES). I plan, however, to keep the old router's same SSID and password. I'm hoping...

Hi there, I'm having an issue with my ever so brilliant IBM Thinkpad T42p, only it's not so brilliant at the moment as it has a wireless issue.

How good is Homegroup security
Got it working between wireless laptop & desktop, very easy setup. The question is how secure is it? I know there is a 10 character alpha(upper&lowercase)/numeric password, which would take a long time to figure out by brute-force. Does anyone know if Homegroup is turned on if one is more likely...
