WAX630E Very poor IPv6 performance

[ftlnparis]

Hi All,

My WAX630E is not playing well with IPv6.

Lots of TCP retransmissions for traffic coming through the WAX630e when IPv6 protocol is used, IPv4 traffic comes through the AP just fine.

I suspect some kind of acceleration is broken on the AP for IPv6.

I'm not sure when this started to happen, but I did recently upgrade the AP to v10.2.0.19

I have done factory reset and also provisioned locally and via insight but issue persists and is reproduceable every time.

Beta firmware has definitely fixed the slow IPv6 performance.

Hopefully Netgear will incorporate this fix in their next release.

Big thanks to to Tomasz from Netgear support team for excellent support and updates, his bosses should definitely give him as pay rise as workers like him give a good impression for the company.

This morning I did some more testing and when device is connected to SSID on WAX630E which uses default VLAN IPv6 traffic runs at full speed.

So performance issue and TCP retransmissions is happening only on VLAN SSID's.

@ftlnparis,

Found out from the NETGEAR Support Team that you have already an ongoing support ticket with them and it has been escalated to the higher tier.  You may want to post the progress of your support ticket.

HI All,

Ticket status:

1. Opened ticket with Negate support.
2. Ticket acknowledged very fast by Netgate (within the hour).
3. Higher tier engineer has taken on the case and has requested logs, activation of reverse ssh to Netgear servers, and packet capture.
4. Awaiting feedback 26 Oct 22
5. Still awaiting feedback 27 Oct 22

Notes

Firmware is latest available V10.2.0.19

IPv4/IPv6 dual stack on all my VLANS

Problem:

Multiple SSID on my access point with multiple vlan

IPv6 traffic on any vlan other than the default "vlan 1" is limited to 40-60 mbps.

IPv4 traffic on all vlan's is working just fine, not throughput limitation

7. 8th November, feedback from Netgear that root cause of bug is fixed in beta firmware. I have installed beta firmware and confirm that on first impression that bug no longer exists, will try for a few days longer to check for stability.
