Windows 7: Can't connect to homegroup via wireless router on laptop.

Can't connect to homegroup via wireless router on laptop.

Problem is as stated, and I swear I have just about tried everything.

Our network is pretty simple, our internet goes into our Modem/Router, which we have our main computer hooked up to, and then we have a second Wireless Router connected to that giving me wifi access to the internet.

I have also had a good read of this link and tried everything as stated in there to no avail: Ultimate Troubleshooting Guide for Windows 7 HomeGroup Connection Issues

There was one thing I saw within these forums I have tried but HAVEN'T succeeded in doing, there was a mention of accessing C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking and clear all the files from within that folder, but when I get to \localService I seem to be looking at everything that's inside my documents I THINK, well at the very least I don't see \AppData.

Now interestingly enough I do have internet connectivity going to the laptop, but when I go into the network tab within computer I can only see the laptop computer itself and not the other computer, the same goes for looking at the same screen on the desktop computer, can't see the laptop computer.

Now I have isolated the problem and it is definitely the wireless router, as I have gotten out an ethernet cable and hooked the laptop up directly to the Modem/Router and both computers can be seen on the network diagram screen. The firewall inside the router is turned off too, and so is the firewall on the laptop, the firewall on the desktop isn't turned off but I've never had any issues with the firewall on litterally anything YET, and the computer can be seen on the network diagram if hooked up directly to the modem/router so I'm assuming that it won't be that.

Computer specs:

Desktop - Windows 7 Home 64bit

Laptop - Windows 7 Professional 32bit.

I also noticed that before posting you guy's always like a screenshot of the ipconfig/all command before posting anything that's wireless so that too is attached at the bottom of this post.

Thanks for looking!

Well I thought and would go that little step further and draw our network diagram in a nifty simulation program called "Cisco Packet Tracer".

Now for those who haven't used/had much to do with packet tracer, with the DSL Modem packet tracer only has 1 Ethernet port and 1 phone line connection, rather than 4 Ethernet ports for connecting things on a wired network like you would see on most everyday modem/routers hence why there is an "imaginary cable link between wireless router and modem router".

Hope that helps.

You'll need to enable hidden files to see the appdata folder.
Open my computer press the alt key...brings up menu at top.
Go to tools>folder options>view, then select show hidden files,folders and drives.
This will allow access to C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking

Now does your adsl modem handle the DHCP for your network
How do you have the router connected to the modem through the Internet port or through a LAN port?

I've attached a pic showing you what port is what and how it's physically connected.

I have the wireless router connected to the WAN port, according to the user manual for my model D-Link router (DI-524UP) that's the port you connect the modem/router to, I could always change it to port 1 and see what that does?

And thanks for the tip on bring up the appdata folder too!

EDIT:

Missed your DHCP question for the modem router. I've just gotten into it and checked, yes it does support it and it's enabled, and I've checked the WiFi router and that too has DHCP enabled.

There's your problem log into secondary router disable the DHCP plug your Ethernet from modem A into a LAN port not wan then power cycle your secondary router...let it boot. If both devices are working as DHCP server they will assign different IP's to the devices plugged in to them creating different LAN's.

Well that did the trick! Thanks dude!

I'm still not quite out of the woods yet though, now that when looking at the network tab to see all connections I can finally see the main computer but it still won't let me join the homegroup i've created, gonna try deleting the files that I haven't been able to delete yet on both computers and power cycle both of them and see how that goes.

EDIT:

Now that I can see the other computer I have noticed something curious with the WiFi router, when I type in the IP address in my browser I now keep getting the message "connection timed out". Any reason why that would be?

Well I just tried deleting the contents of C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking on both computers and rebooting them, no joy

Have you deleted the original homegroup, and made a new one?
Are both the modem and router in the same location? (room)
If so disable DHCP on your ADSL and run the DHCP through your D-Link and plug your desktop into that.
You would have to log into your D-Link and turn on the DHCP and plug back into your WAN port and I'd reconfigure the wireless while your there.

No I didn't delete the original homegroup, its a bit late during the night over here in Aus so I'll give that a go in the morning. As for the Modem/Router and WiFI/Router yes they are, I'll give that a try tomorrow too, if I have no success getting into the D-LInk Wifi router again I'll just hit the tiny reset button and quickly reconfigure it and go from there.

Thank you so much for your help mate, appreciate it heaps!

The problem I see here is that you are using one of those router/modem combo's plus another router. This arrangement hardly ever works correctly and isn't worth the hassle of trying to make it work right.

You really need to get a regular modem then plug it into the WAN port on your regular router. This makes for a hassle free and reliable network which I'm sure is what you want.

And I'm wondering why your router says Linksys and also D-link?

In a nutshell, all of your problems are from setting up your network incorrectly and have nothing to do with the Homegroup at all.
