Well, the titel speaks for itself... Which solution do you experts recommend?

Use my current tweaked Alcatel Speedtouch Home (to Pro) in combination with the WL-500g Premium or replace the Alcatel and use the WL-600g..?

At this moment the PC's upstairs are wired to a switch and from there to the Alcatel.
Basically, my idea was to use the new WL-500gP or WL-600g to enable the PC in the livingroom to have internet-access and to enable it to print to a (USB)printer.

I've also read some problems with the WL-138g (also the WL-138gE..??) connecting with the WL-500gP...
Does it have the same problems connecting with WL-600g? And does it make any difference if you use the WL-138g or the WL-138g V2...???

Please post your advise.....
