I have the following setup:

Cable modem connected via ethernet to netgear fs108 8 port switch with 3 connected devices:

--NAS unit
--PC 1 - win7 sp1 64bit
--PC 2 - winXP sp3 32bit

All ethernet cables tested and ok

Here is the problem I have:

PC 1 - full internet access - no access to NAS or PC 2
PC 2 - access to NAS - no internet access or access to PC 1

I have tried using different ports on the switch and the green lights illuminate and blink with activity. Connecting the modem directly to each PC gives internet access and connecting the NAS directly to each PC give access to that. Each PC is not visible from the other and the NAS is not visible from PC 1

:confused:

Oh no, I can see some facepalms coming... I forgot to add in a router, lol, would a standard wireless router work? :

Cable Modem -- Wireless Router -- Network Switch -- PC1 / PC2 / NAS

Thanks bremen, much appreciated. Virgin media put it into modem mode as a last resort after months of low download speeds. It is the 2nd hub in as many months and in 'normal' mode I get varying speeds from 7 to 61Mbps but in modem mode it is constant between 61 and 68Mbps. Had dozens of conversations, 2 engineer visits and this is their solution.

The story continues bremen, they did supply a wireless router, but guess what... that doesn't work either, works for about 2 to 3 hours, gets hot and cuts out ! I've got a spare router in the garage, will try that first and to be honest I would rather pay for a router than go through hours on hold between departments at VM again !!

OK, now this is driving me insane - tried 2 routers - no internet access for either pc - took out the network switch and nas and tried with the following:

cable modem -- router 1 -- PC 1 .... no internet
cable modem -- router 1 -- PC 2 .... no internet
cable modem -- router 2 -- PC 1 .... no internet
cable modem -- router 2 -- PC 2 .... no internet
cable modem -- PC 1 .... internet !
cable modem -- PC 2 .... no internet

Made no difference bledd. If i connect the modem directly to each pc one at a time then I get internet, if I add in a router then i don't get internet on either pc, individually or both connected together. The routers green lights illuminate stating internet access and ethernet cables connected, I connect the cable modem to the WAN blue slot and the ethernet to the PC in one of the yellow slots. I reset the router and uninstalled / reinstalled the network adapters in the system.

Both wireless routers are at the bottom of the garden somewhere wherever they landed, the virgin home hub is back in normal mode and my speed is back down again to ~22Mbps despite paying for a 60Mbps package. At least I now have both PC's online and both PC's are visible along with the NAS on the home network. Thanks for all the advice though
