So when the computer was back on I noticed I totally lost the internet connection. Even though the CAT5 cable is connected, the laptop does not recognize it at all. It simply says "Not Connected". And just today I realized that whenever the Ethernet cable is connected to the computer the computer periodically(every other second or so)makes a faint buzzing noise. This is something I had not noticed before. I replaced the cable with a new one and the same thing still happens.
I think the modem is working fine since my roommate can access the internet. On the modem where the lights should be on for my connection, it is periodically blinking.
Anyone got an idea as to what is happening?
Check device manage for the network driver
Please go to start>search>type device manager.
Are there any "unknown devices" with yellow triangles on them?
Is you driver there , listed, and working?
If your driver is missing, or there is a yellow triangle on it, you will need to update it.
