It has recently come to our attention that older firmware versions of the Netgear M4300 can potentially cause throughput issues with 2.5Gb/ 5Gb links.
Here we see a TCP flow with many retransmissions and a non-optimal throughput.
In order to resolve this issue, the switch should be upgraded to the latest firmware version.
- Download firmware
2) Log in to your Netgear switch via the web CLI.
- The default IP is 192.168.0.100
- Username: admin
- Password excentis
3) Upload firmware.
- Go to 'Maintenance' → 'HTTP File Upgrade'
- Click 'Apply'
