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

Is the 'cable modem' you mention actually a combined cable modem and router?

If it's just a modem it would explain your problems.

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

Any router that has a Ethernet WAN port will work. Normally described as Cable/FTTC routers.

Why did you put it into modem mode in the first place?
 
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.
 
If Virgin have forced you to use modem mode I'd kick up a fuss and see if they'll supply you with a separate router. I don't see why you should have to play anything extra to use their service as intended.
 
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 !!
 
Fair enough.

Be aware that some older routers aren't fast enough (WAN to LAN) to handle a high speed cable or FTTC connection.

If you're after something new look back through the previous posts in this forum. The question has been asked and answered numerous times.

Assuming PC2 does in fact have two network cards and im not reading that wrong:

Connect PC2 directly to the modem, get it working (presumably DHCP), then connect its other NIC to the switch (that has PC1 and the NAS attached) and set a static ip on it (i.e 192.168.0.1/10.0.0.1/etc) and set PC2 to share its internet connection with other network computers.

If all goes to plan (I haven't set up a network like this since pre Vista) PC2 will get an internet connection due to its direct connection to the modem on NIC1, and act as a router on NIC2 enabling the NAS and PC1 to access the internet (PC2 will have to be on for them to do it).

(Im offering this as a stop gap not a full solution)
 
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
 
Take the switch out of the loop for now.


Get a fully working cable router, reset it to default.

Connect the cable modem to your WAN/internet port on the router.

Restart all your computers and plug them in one by one into the router, until they are all plugged in. Reset all the network cards to default settings before doing this.

-Restart any that have problems.
 
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. :(
 
/thread

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 :)
 
If the superhub is in modem mode, you need to connect it to a router, and then switch to the router with the devices hanging off. You're probably having config issues on the PC, looking for a different default gateway or what not.

Turn on DHCP on the router, and make sure the devices are set to get an IP automatically. This is really basic stuff, so I don't see any reason when using DHCP that it wouldn't work.
 
Could the OP's most recent issues with the routers be related to the MAC addresses?

It has probably changed since I had a Virgin (NTL at the time) connection, but the IP used to be tied to the MAC address of the connected device. To use another device you had to wait for the IP to expire (or manually change the MAC).

If the OP's IP was linked to the MAC address of one of the PCs then it could take a bit of messing to get a valid WAN IP for a newly connected router.
