This is getting more confusing as time goes on. A poster in another topic says IPv6 support not fixed in 3.8.9.2_BT. A user in tis topis says it is. Elsewhere they also hint that rebuilding from scratch fixes a f/w rule issue. I’m not sure that I have the energy to do that again!

For me, the new firmware seemed to fix an outbound IP address issue for NAT loopback, but multiple other issues (incl f/w issues remain)

Note that the release notes state a known issue with firewall and static routes. Maybe the issue is wider....

I'm loathe to flash the firmware for what will be the 5th time to change the management port which will then stop my SSL vpn working as well as all the other problems this firmware causes :x

Did you get any response from Support, I'm now using 3.8.9.3 on a 2925 and believe I have the same IPV6 issue with a 10 sec delay fallback to IPV4 and IPV6 is no longer working at all in my tests but that could be because of the new ISP Router (need to swap and test)

Nope, I sold it and am now using a Firebrick

We have just upgraded to 3.8.9.3 and wish I had found this thread first what a friggin nightmare!

12 x 2860 Routers upgraded just before we roll out Samsung Tablets to all our shops.... now we find in our test shop critical systems have all failed (lucky its before the rollout to the other 11)

I have downgraded it back to 3.8.4.5 and all is fine.
I am hoping upgrading to 3.8.8.2 will be stable but seeing as we never used that version prior I'm asking for your advice.

Our simple setup.
Wireless Access Point (Netgear or Tenda) connected on LAN6 (VLAN'd for isolation)
Teamviewer quick connect broken on every Android based tablet (won't connect to generate TeamViewer ID)
Trailapp.com (critical business resource) broken on every android tablet (cannot display page) resetting the cache in Chrome worked once but not again. Installed Firefox worked once but now refuses to connect.

The above items appear to work fine on any IOS device (not tested extensively) but both my iPhone and iPad generate TeamViewer IDs and can access the website...

I know you've all mentioned problems with 3.8.9.1 and 2 but I take it 3.8.9.3 is also shoddy as hell or am I experiencing a new phenomena?

Any advice would be helpful, thanks.

Any problems with this 3.8.8.2 version?
Is it ok to downgrade to 3.8.8.2 from 3.8.9.3 without resetting as getting onsite to all the shops is problematic?
Are the problems I am experiencing with 3.8.9.3 known to you guys or should 3.8.9.3 be working perfectly?
