    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Thanks for the reply. I was hoping of something a bit simpler (and found in the OEM firmware). Oh well, I am just happy that I don't have to futz with my phone every time I get home!

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Looks like you hit on something with IPv6. I could not find any way to set the DNS Servers on my phone to IPv6 addresses, IPv4 yes but that doesn't help. So I completely disabled IPv6 on the R7800 and now my phone seems to be working fine. I can now leave my wifi, go to 4G, go to local comcast...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Strangely the phone will work on my Wifi about 50% of the time if I manually disable Wifi on my phone before I leave the house, and when I get home manually close all apps and enable Wifi on the phone. I guess this is just gonna be "a thing" with this router, unless someone knows a WireShark...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    I did some captures, made them as short as possible. First time Wire Shark user, so I really have no idea what I am looking at. Verified DNS Lookup broken on R7800 wifi, switched to local xfinity wifi and it works, re-connected to R7800 wifi and verified DNS fails, repeat... After the fail...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Did not help!!! Set manual DNS servers on the phone for 2.4Ghz and 5GHz R7800 wifi. Reboot phone, then: -With phone connected to the 2.4GHz R7800 wifi, successfully use DNS Lookup app to find www.google.com -Change to local xfinity wifi, lock screen, wait a minute, unlock screen, successfully...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Laptop is always unaffected. The problem has been duplicated on my GF's android phone. Next up - try manual DNS servers on the phone. If this works, is it some conflict with the R7800 or the Comcast modem?

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    And even crazier - when in fail mode (R7800 wifi imap/pop email doesn't work), the DNS Lookup app on the phone hangs/fails for ALL web addresses! www.google.com www.sony.com www.nbc.com etc...... Yet, I can use a browser (firefox) app on the phone to open these pages just fine????

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Ok, so first quick observation. I installed Whois DNS Lookup app on my phone. Verified the DNS Lookup works on my wifi, changed to 4G verified again it works, changed to local xfinity wifi verified it works, back to 4G-works, back to my wifi and BANG - DNS lookup tool HANGS never resolving. Go...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Except when the phone apps don't work, I can continue to use my wifi to check email on my Laptop (thunderbird IMAP/POP email client same port/authentication). Of course my laptop hasn't really ever left my wifi network for any amount of time, joined a mobile network, then rejoined wifi.

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Well the problem affects non Comcast email also! If I connect to the local "xfinity wifi" the imap/pop apps work, switching back to my R7800 no go...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Well that lasted all but 24hours. Just got back home from the grocery store and I'm back to square one, the adroid imap/pop email won't connect. I also just tried the native "xfinity connect" email app and it's not connecting either. Next test is to add some non-comcast emails to the android...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    So just for kicks, before I left for work this morning, I rebooted my comcast modem. Ten minutes after the modem was back up, a lot of my devices still reported no internet. When I accessed the router admin I saw a big red error on the internet, so I ended up having to reboot the R7800 to get...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Some interesting posts! I actually upgraded my my comcast service to 1Gbps and purchased a new modem at the same time I got the R7800. That's when this issue started. So it very well could be a modem/comcast issue. I have do have three comcast.net email addresses setup on the IMAP/POP app(s)...

    IPv6 R7800 wifi Android DNS/TLS/IMAP stops working

    Ya, I've tried several different android email apps. Also ALL variations of IMAP/POP, ports, and security. Router is just using stock netgear v1.0.2.68 Only have one Port Forwarding service rule for a Media Server PC.
