Hotfix For:

We have recently been made aware of a throughput issue affecting our AP product. This issue specifically impacts the data reception (receive direction) performance and has been reported when using the following network cards:

  • Intel BE200
  • Intel AX210
  • Intel 211
  • Intel AX 201/411
  • MTK MT7992

It's important to note that the transmit direction is not affected, and this problem seems to be isolated to these particular models of network cards.

For users encountering lower throughput on the receive direction with these network cards, we have made a date code available for download. This update is aimed at addressing the compatibility and performance concerns.

If you are currently not experiencing any issues, we recommend continuing with your existing setup without any changes.
