Wireless Internet Access

delian · 14-11-2004, 10:06

Hi,

I am being driven up the wall trying to access the internet via a wireless access point. I have the following set-up.

Workstation
Cable modem (NTL)
D-Link DWL-2100AP Wirless Access Point.

All of these are plugged into a little Ethernet hub and the workstation happily has internet access.

Addtionally I have a laptop with wireless card. I have a full connection to the Wirelesss Access Point i.e can ping it and view the admin console via a browser. However I cannot get internet access.

The Access Point has an IP address of 192.168.0.50 and I have statically assigned the laptop an ip address of 192.168.0.51. I notice that the cable modem seems to have an IP address of 192.168.100.1. I did tinker with changing the IP address of the other two to be along the lines of 192.168.100.xyz but no joy.

I am missing something stupid here I guess - can anyone put me out of my misery ?

Thx

The only thing that doesnt seem to make sense there is your comment about the modems IP address - you modem should have an external ip address - that your access point should pick up automatically......not an internal ip....

This setup will not work as you have more that one device's mac address presented to the cable modem. To be able to have more that 1 pc connected at the same time you will require a broadband router. There is more info on this link.

Hope this helps

OK - well I maybe getting confused. I mentioned that as I can connect to the cable modem admin console via http://192.168.100.1 but cannot do the same from the laptop...

And that is because you can only have 1 device connected to the modem at any one time. You need a broadband router to be able to do what you are doing.

What default gateway and subnet mask do you have on the laptop ?

Not quite sure what an "access point" does (extend the local network wirelessly?), but I'm guessing it does not do as much as a broadband router.

I Think you either need to replace it with a wireless ROUTER, or add a single port (or more) router between the cable modem and the rest of your network

http://www.ebuyer.com/customer/produ...duct_uid=52897 - No idea how good this is with NTL, but it should provide the necessary routing capability, and a USB print server as a bonus.

Other than their prices, it's hard to recommend Ebuyer, great so long as you don't have a problem.

Their returns procedures are a frequent cause for complaint.

There was a truly great ebuyer spoof site, and I can't find it.

The pity is, that they WERE great, once upon a time, the people were interested, they knew their products... then they got too big, too fast, and that was the end of good service.

I do think that what is needed here is a router. The wireless access point will have no routing capability at all

To echo the other replies....

You need a wireless *router* & not a wireless access point.

If you get a D-Link DI-604 router you can plus the workstation and the WAP in to it.

This works for me.

Hope this helps.

Many thanks to all for the replies.

I have swapped the Wireless Access Point for a router (D-Link DI-624). After firing up the router things looked promising until what would appear to be the router crashing a short while after switching it on - it refuses to reset via reset button, status light goes off and all the Local Network Led's light up and remain on even though I have no cables plugged into the router. The Ethernet light on the cable modem goes out as well.

Unless I am no being extremely dumb (?) I think it looks like a trip back to the shop again tommorrow ......

What a bummer

how unlucky can you get

??? NO cables plugged into the router and the Ethernet light on the cable modem goes off?

Do you mean ONLY the cable from the router to the modem is plugged in? If so, is it straight-through or cross-over? (NTL peeps - which should it be, or doesn't it matter?)

Just to be clear - the WAN port on the router should be plugged into the CM. the Workstation should be plugged into the router, and the lap-top should connect wirelessly through the router.

With the Ambit (silver) cable modems, at least, it shouldn't matter whether you use a straight-through or crossover Ethernet cable.

Ok it should be a straight cable

The rest is correct. Make sure you have rebooted the cable modem. connect the router and the WAN light should be on. Same as the ENET light on the modem.
