Netgear GS608 v2<\/figcaption><\/figure>\n

The LAN connection from a computer to my home-network stopped working from one day of the other. First I thought, it could have to do with the network-lan-card in the specific computer. Sadly I did no detailed test and did not locate the problem exactly.<\/p>\n

Weeks later I realized, that other computers in the network couldn\u2019t connect too over LAN. Next I updated the router (FritzBox 7390 ) to the newest firmware version (6.25). This didn\u2019t solved the problem. If a Computer was directly over LAN connected to the FritzBox, everything worked. So the only bad thing between could be the Netgear 8 Port Switch GS608 v2. Strange was, that the LEDs in the Switch light up, if a device was connected by cable.<\/p>\n

Because the switch is capable of 1Gbit\/s it has two LEDs per Port (green an orange). If a 100Mbit\/s device is connected, the orange LED shines. If a faster, 1Gbit\/s device is connected, the green LED shines.<\/p>\n

I recognized, that the FritzBox (capable of 1Gbit\/s) was detected by the switch as 100Mbit\/s = slow = orange light. My Laptop could only connect every 10 seconds for about one second. Really strange.<\/p>\n

If I connected a 100Mbit\/s Switch between my Laptop and the faulty Netgear Switch my connection to the network worked!<\/p>\n

It turned out, that 100Mbit\/s connections through the Netgear Switch worked, but faster connections caused problems.<\/p>\n

Also only a number of devices were working properly, if more than 4 devices were plugged in, the later added devices couldn\u2019t establish a connection \u2013 the LEDs of their ports stayed dark.<\/p>\n

I didn\u2019t know, what was happen with the router, which worked fine for 7 years. I searched the web and found randomly a post about a fix for this router https:\/\/tinajalabs.wordpress.com\/2011\/03\/20\/netgear-gs605-v2-fix\/<\/a>. The writer recognized, that his internet-connection was slow and searched the web and found, that bad capacitors in the switch can cause the problem.<\/p>\n

I opened up the switch (4-Torx screws on the bottom under anti-slip pads) and saw the two blew up electrolyte capacitors. A third electrolyte capacitor was fine.<\/p>\n
