Netgear M4300 - Upgrade Firmware
Posted by Craig Godbold, Last modified by Craig Godbold on 03 June 2022 01:57 PM

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.

1) Go to https://www.netgear.com/support/product/m4300-96x.aspx#download

  • 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'
