MX17.10 bug with built in wireless?

[IT_Magician]

After the MX17.10 upgrade to a mx64w everything works great except built-in wireless clients have horrible lag between loading sites. I say lag because if I go to www.cisco.com it spins and spins and spins and while trying to load I can open command prompt, NSLOOKUP immediately pulls correct IP, and I can ping no problem. This happens to ALL wireless users which is VLAN 1, but our hard wired VLAN 1 devices on same subnet do not have the issue.

We replaced the Meraki with a MX67w running MX17.10 and have same issue.

I then try a new browser (Edge) and go to www.meraki.com and it just spins and spins (eventually loads, 30+ seconds) but while that is loading I have zero packet loss to www.meraki.com via the command prompt, and all hard wired devices can access that without any issues.

On the phone with Meraki support now, but anyone else with built in wireless having issues?

It's a bug, downgrade It to version 16.16.6.

Thank you, you were 100% right. Immediately fixed the issue. We had 2 other known cases and also downgraded them and it fixed, so we ended up downgrading all with built in WIFI back to 16.6. 

Meraki should do a better job making support aware. We spent hours doing packet captures to no resolution.

Seems that I don't have an option to downgrade from 17.10 back to 16.6.6

Any word on which release this might be fixed in? Having the same issues.

I guess they went ahead and released 17.10.2 anyway and I'm having the same issue at two of my client sites. Sigh. MX64W: LAN is fine, wifi is trash.
