HP 1820 24g J9980A Issue

[jezi55]

Just installed a couple of HP 1820 24g J9980A around my school and i'm experiencing some really strange issues. When clients connect to this switch they get a yellow exclamation mark on the network interface saying no internet. The clients also receive no group policy's either. If you browse to a website you get the internet but if you ping 8.8.8.8 it fails... BUT i can ping from the switch and i get a response Reply from 8.8.8.8: icmp_seq=0 time=19135 usec. This is causing issues for me as Avast will fail to get the latest update definitions. I can ping my router and also all my servers so really not sure what is going on and any advice would be great at this stage. I have turned on and off the following features : Jumbo frames, flow control, spanning tree. I have recently update the firmware on the switch to PT.02.01 to see if this would solve any issues but it is still causing problems.

 

Many thanks[TABLE=width: 971]

First thing I would do is disable the features 'Jumbo Frames, Flow control and Spanning tree', triple check the IP configurations, have you typed everything correctly?

 

Once the above is done, now try to release / renew their IP and check the internet.

Sometimes, it's the simple things that are causing the issues, process of illimination.
