Hello there!
I know that this router is completely outdated, but still. Faced with such a problem. Bought a few months ago on ebay cisco isa570w. Fully operational, everything is great. But now I noticed that when the speed on the Internet tariff is equal to 700Mbps, cisco in the LAN network issues from 300 to 350 Mbps on the computer. I tried to connect the wire to the computer, everything is great speed 690 Mbps. What could be the problem? I tried to ask this question on ServerFault, but no one answered.
The firmware costs 1.12.20.
The router is reset. No features are connected.
