DG834GT not worth having for Mac users
Thanks for your help. So there are no benefits to having the GT if you are on a mac? What about online 360/PS3/Wii gaming?
Anyone know if O2 supply a router?
O2 do supply a router but I don't know what model offhand (although I have briefly looked at one). It has 4 LAN ports and it's wireless so you should be able to get 802.11g but I can't comment on how good the firewall (if there is one) is.
The XBox 360, PS3 and Wii only support standard 802.11g which runs at 54MBps (theoretically). IIRC the Netgear turbo standard bonds a couple of available wireless channels together to achieve what they call 108MBps which is in reality about a 25% increase in transmission speed and a slight increase in range in some cases but only if all units in the network are using relevant adaptors (which Macs don't have at all).
In real terms you have to have matching Netgear 108MBps 'turbo' adaptors running within a completely Windows PC network to get the speed increase. If you were to introduce a standard 802.11g device to the network everything else would slow down to the 'standard' speed in just the same way that a user with old fashioned Airport (802.11b) would slow a wireless network to 11MBps.
Getting the GT model, therefore, will cost more and you won't get the benefit if you own anything other than a Windows PC.
In fact, if you do have a games console that you'd like to get online wirelessly too you're stuck with 802.11g for the same reasons outlined above.
And finally, in an apartment block it's possible there may be a lot of wireless adaptors in close proximity so you may get degraded signal quality from the competing base stations. It's possible that a stable signal could be hard to come by so it's worthwhile tracking down routers which have a decent number of aerials or signal quality.
One remedy is to get your base station to broadcast on a less commonly used channel (they go from 1 to 11, most wireless routers default to channel 6) or perhaps even resort to good old fashioned patch cables.
