Telewest cable modem Webstar EPC2100R2 problems

Hiya

Having problems connecting a 3COM wireless access point (3CRWE454G72) to a
Webstar EPC2100R2 telewest cable modem, it looks like the cable modem is

not assigning an IP. The WLAN led on the 3COM flashes continually, the
wireless laptop sees a good signal.

I have tested the 3COM on my Origo router and Pipex connection , the
wireless connection establishes within seconds. and the router sets the IP
just as quick.

Can I connect a WAP direct to a Webstar , do I need a different cable
Xover/straight through , do I have to connect to the Webstar and alter the
configuration ?



Regards

I'm a bit baffled by your question as looking on the 3Com website for
this model suggests it is purely a Wireless base station and not a
router.Details here http://tinyurl.com/23hv2d

Your post refers to a WLAN port but looking at the manual suggests that
this is to indicate that the wireless LAN is operational not a WAN port
port. Manual here http://tinyurl.com/ytmqou

The answer would appear to be that you cannot connect the device
directly to the modem as it is not capable of being assigned a WAN IP
address.

I'm further confused as you seem to have both a ADSL connection and a
Cable Modem connection.

Bottom line would appear to be that you could use your 3COM as an access
point onto your existing network but you need a router (with WAN/LAN
ports) to use as the bridge between Telewest's network and yours.

Not a complete answer ... but then again we dont have full information.

My 10p worth

ps is your Origo acting as a DHCP server as you dont mention configuring
IP addresses on the 3COM?

Sorry for your confusion ;-)


Pal has a Webstar EPC2100R2 telewest cable modem

Pal has PC connected to the only port on it

Pal buys a Laptop with wireless conectivity

Pal want's to disconnect Pc from Webstar EPC2100R2 telewest cable modem and
connect a wireless access point

I have a 3COM wireless access point (3CRWE454G72)

Question ... Is the PC in the old config getting an IP from the Webstar
EPC2100R2

If so should the Webstar EPC2100R2 provide an IP to the 3COM

Question ..... What device should be used to allow Wireless access to the
net via the Webstar EPC2100R2
