Hi, you will find it very difficult to re-configure your O2 wireless router without an Ethernet connection; get the settings wrong and you have lost your wireless connection.

First step to eliminating the wireless is try the connection when connecting via Ethernet, if all is well then you appear to have a wireless or driver issue under OSX

Hardly the attitude for someone who is trying to appear helpful is it.

What laptop? Some wierd Mac? I didn't know there were any laptops without ethernet.

Re one of your posts somewhere here, what router are you using if it isn't the O2 box?

There are some free tools which allow you to monitor connectivity between a central test box and the router at the customer end.

If you had one of those you wouldn't be hampered by "thinking different" and you wouldn't need a Window box either.

If you had one of those it *might* show if there were connectivity problems (e.g. packet loss) between your router and your ISP.

Where can you get such a tool?

Try http://www.thinkbroadband.com/ping


You can do this ping test stuff at the same time as the other suggested stuff wrt checking your wireless connectivity. I've tried InSSIDer but couldn't find an SNR indicator only a signal level indicator. Netstumbler used to have both signal strength and SNR. A high signal level is not much use if there is another high level signal on the same channel, causing poor SNR.

Also on similar lines I'm not sure how InSSIDer handles non WiFi devices in the relevant bands - e.g. if someone has a video sender on the same frequency as your WiFi it won't affect your received signal level but will affect the signal quality; Netstumbler could show this as poor SNR, but can InSSIDer show it at all?

Put more briefly: try using different channels for your WiFi and see if it helps.

Why not - he works with PCs, he could get one from somewhere. He obviously knows his way round windows and all the diagnostic tools are available for windows.

Does TBBmeter run on OSX?

Could be a MacBook Air. I don't think they have ethernet, although Apple do a USB to ethernet adaptor.

Thanks.

I do indeed have a macbook air which is ethernet free. Also the master socket (only working socket in the house) is on top of a kitchen cupboard so standing in the kichen to surf is not ideal.

I am using a netgear DG834G before that I was with O2 so used their modem but had the same problem

What sync rates, attenuations, SNR margins, errors are reported by the router.
