I got into my neighbours Belkin wireless (well my laptop connected to it str8 away). Also the password on the Belkin was blank, so I could get into the admin panel without a password.
I installed a DLink WAP+PCMCIA card for someone and had nothing but problems. Random disconnects, bad wifi range etc. Put in another one to extend the range and had even more problems.
I ended up putting a old Linksys in there with a custom firmware which allowed the WIFI to be amplified and the range was 2x that of the 2 DLink WAP's
I think a while back, the DG834G was considered one of the best gaming ADSL routers? I remember it getting loads of awards and there was a review on adslguide or something with some tests where it was 1st in almost all of the tests, including the ping test.
