Wireless madness

This is insane. Spent over 6 hrs yesterday night trying to get my home wifi working properly, and must say i failed yet. Common presumption, that if all the components are the same brand - no problems should appear, DOES NOT WORK FOR SMC! I hate this company pretty much at the moment.

Problem is, that 802.11B usb client [ SMC2662W_V3 ] doesn't quite work with new 802.11G (said to be 802.11B compatible) router [ SMC2804WBR_V2 ]. It connects, but downloads are slow and after some time it starts hanging. Interesting point is, that the least standard's compliant piece of wifi hw i have - 802.11B+ (22mbps proprietary extension) pcmcia card [ SMC2402W ] works like charm.

Technologies are evil :-(
