Hello, I've recently bought a new Acer laptop for my mother which I loaded with a Win 7 ultimate retail. The issue is that I've made a homegroup on my other computer (same OS but not a laptop) I cannot find the homegroup on the laptop, if I create a homegroup on the laptop i cannot find it with my main computer and vice versa. With the laptop I can ping my main computer, but not the other way around. Im using a normal modem, then I have a normal router which my main computer is connected to, connected to that router I have a wireless one, both have the same manufacturer (Netgear). No issues connecting to the internet on any of the computers. I've tried to reset router/modem all that. Tried creating new homegroups on both of the computers. On the laptop i can access the shared files on my main computer by (Run: \\Test-PC) Cannot access the laptop with my main computer that way. Really need help on this one, never had this big issue with networking with computers, especially not when both have windows 7. Thanks for any tips. /Cheers.

clear up something here you state "Im using a normal modem, then I have a normal router which my main computer is connected to, connected to that router I have a wireless one, both have the same manufacturer (Netgear)." So from this I get that you have a router and then you daisy chained a second router to it correct??? Is this the case?? if so I think this is your issue. The second router I will assum you have plugged into a lan port of the first router, and the second is also running DHCP and giving out IP via the wi-fi..correct??? So yes anything behind the second router would access to devices upstream (main computer plugged into the first router), it is normal that device upstream can not see devices down stream this "how things work" in the TCP world. a work around would be to log into the second router and turn off the DHCP server and allow the device behind the second router to get IP's from the first router, this way ALL DEVICES would be on the same IP range and your homegroup would work. Of course all this is ASSUMING your router / wi-fi support windows 7 (IP6 is needed for homegroup), if this is not the case, please post more info in the way of IPCONFIG from the machines and the make / model of the routers.

Under network and sharing center, next click on view network computer and devices, are you able to see your's as well as the rest of the network computer? Prior to doing this, ensure all the network comp or laptop is power on

Sorry for not updating, forgot about this post. Anyhow I know that the issue was caused by me connecting the WLAN router into the "main" router's LAN port, and yes it was its own DHCP server so I did turn that off, didn't solve the issue + now ofc I couldnt access the wifi from my phone either. I just wanted a way to get by that if possible, but I solved it by simply removing the wired router and using only the wireless one, was the easiest least painful solution anyway, and haven't had any issues being connected to the wireless one so codous to netgear I assume. Still thanks for quick response, this issue is now resolved.
