I received two broken Tranzeo WLAN antennas last week. One has water inside; you can hear it slosh around. The other had no noticeable outside damage. After removing the cover and dissabling the case, I removed the board. You can see the noticeable overload damage to the National Semiconductor LM2599S.

When it comes to network devices, such as switches, faster is better. However, smaller is not always better.
One such case at the House of Onyx, Inc., For two years, two computers have used a single switch to relay traffic to the gateway. A very light load for even a 4 port switch. The first year it was a 3COM switch. I started to see intermintent connections to the LAN. Finally it failed. The 3COM was replaced with a Linksys Network Everywhere 5-port switch. Even smaller than the 3COM.
Two weeks ago the same intermitent connection problem returned. I tested the computers and the newly added printer. Moved cables around. The problem remained. When I felt of the switch, it was uncomfortably hot.
I had an old Asanté 8-port 10Mb hub from a previous upgrade. The hub is built solid and runs cool to the touch.
