Hi there, i am pretty proficient with wireless networks and have installed many, loads even with macs, but have never encountered a problem quite as severe as this. Unfortunately the customer is remote, so all i can do is talk through stuff on the phone and reverse VNC to see what is going on.....

The dilemma is as follows:

They've got a Netgear wired router with an inbuilt modem, into that is plugged a Belkin wireless access point. Before you say anything, this setup works fine, they have been using it really happily with 3 Windows laptops which access the access point wirelessly and there is one laptop which is wired into the main router. No problems. They then bought a powerbook and it detects the SSID of the access point, it receives a valid IP address in the range and subnet mask, but the internet connectivity, well, it leaves a lot to be desired. If the mac tries to connect to the access point, the Windows machines ALL have very very limited or sometimes no access immediately after the Mac tries to connect, so it basically knocks them out. But the Mac gets no Internet access either - however, it can get to the router's IP address, that is the actual wired router, so the wireless appears to work!! So why does it cut out the PC's and why if it can see the router configuration page and can access it no problem, is it not shared the internet???

Equipment used:                                 Laptop 1  Laptop 2
DG834 Router |----- Belkin 56G WAP    ---^----------^---------> PowerBook (built in wireless of course)
                     |-----Wired Laptop

I find it unbelievable that the Mac can get right back to the Router, but can't go that one step further onto the Internet, if it can get to the router, then it shared the net surely, this is why it makes me think there must be some simple configuration setting actually on the Macintosh itself, unfortunately, as you probably gathered, i'm not proficient enough on Mac to know where this setting would lie - and yes i've checked the System Preferences > Network > Airport settings, and they are all OK as far as I can see.

Any light on the matter or previous experience with resolution will get the points!

Cheers,

Henry
