Network Connection Problems
Assume you own a cabled network device and you are not able to establish any connection via one of the UTP wall sockets,
did you consider the following:
1. Has the UTP socket already been patched?
To check this, send a mail to: support@isg.ee.ethz.ch
2. Has my device already been registered on the DHCP server?
If not, send a mail to: support@isg.ee.ethz.ch
3. Is the network cable I'm using physically ok?
- Ask the hardware responsible of your Institute for an alternative cable.
4. To reset the UTP socket, unplug and replug the network cable from the UTP socket for 20 to 30 seconds.
5. Did I deactivate wifi of my device?
- If not, do so, because wifi activated in parallel to cabled networking can cause problems.
6. Did I deactivate 802.1x authentication of my device?
- If not, do so, because if 802.1x is activated the registered MAC adress will be ignored, as a consequence you won't be able to get into the correct network.
7. Has a dumb switch been connected between my device and the UTP socket?
- If yes, pull the dumb switch' power cable for approx. 20 seconds to empty it's port cache. After that, try again.
8. Are the network settings of my device correct, e.g. did I activate DHCP?
- Please check
9. Is the hardware, e.g. network card, of my device working correctly, are the LEDs blinking?
- Please check
