Extend non apple WIFI with new Time Capsule!

I am using an older utility and an old dual-band TC, but these are the options I have available.

The only way to extend non-apple wireless router is using WDS and that is with the following limitations

1. WEP is the best security you can get. And that is not adequate now.

2. It will reduce N wireless on the Airport to G. ie max speed wireless with WDS is G.

I have just bought a Time Capsule, tried to extend my WIFI with it, but with out any luck.

You cannot extend non-apple wireless routers with apple routers. They use a proprietary system.. unless you are prepared to lose speed and security back to the dark ages.

Apple do not make wireless extenders for other brands.. only for their own.

You can use EOP (homeplug) connections or ethernet to plug the TC into the other router and create a wireless of the same name if you want roaming. This is often the best alternative.. or buy a real wireless repeater. Although IMHO repeaters are more trouble than they are worth and I think you are always better wiring it.

OP is saying

Can it really be true that, I can't extend my WIFI with a extreme/TC when I can do it with express airports?

He has an existing wifi with Apple products (unless I misunderstood the questions). Cross-vendor extending does not work well, because no one follows standards anyway.

I can't extend my WIFI with a extreme/TC when I can do it with express airports?

Users really get confused with this, because the Express can "join" most 3rd party wireless networks....for use with AirPlay (used to be AirTunes)....but the Express does not "extend" or "repeat" the wireless signal when it joins a network.

Unfortunately, there are likely countless numbers of users who think that their Express is "extending" their network, when it is not.
