I have recently upgraded my set of E2500 v3 devices to k3.x r36330 mega trailed builds. One is running as a primary (regular setup) and the second one is running as a wired switch+AP (wired connected to the primary). Both are experiencing WiFi to Internet connectivity issues. LAN to WAN or WLAN to LAN keeps working fine but WLAN to WAN stalls. Signal is fine. I left the advanced settings in WiFi alone. I have to disconnect phones/laptops from WiFI the reconnect them again and then internet works fine again . Any idea what might be causing those? Thanks! _________________ WRT54G v6, WRT160N v3, WRT610N v2, E2500 v3, EA2700 v1

Try the latest firmware version instead. There are numerous bug fixes. _________________ Linksys WRT1900ACS V2 dd-wrt bs r35034

Stock firmware? It isn't patched for Krack or a bunch of other things. It has pretty much all the same damn un-patched code the stock E4200 v1 firmware has. He is already running the latest DD-WRT build. Anyhow, sounds like the GTK re-key interval is set to default, and for some reason, that is STILL a problem. I wound up setting that interval to 0 because it kept filling the syslog with garbage and causing issues. I presume you followed the wiki to flash a v3 and have upgraded with non-trailed builds and have at least done a reset to defaults via the GUI before and after every flash and manually re-configured. I've left my E2500 V3 stock with the latest stock firmware as it is only one of my backups.

I upgraded these to DD-WRT a few weeks go for the first time. I started with the instruction for the hw+rev specific wiki page and then hunted this forum for tweaks, pros and cons for that specific hardware. In the last few weeks I have tried 36247 both k2.6 and k3.0 then moved on to 36330 k3.0. I didn't notice the drop issue on k2.6 36247 but I didn't stay more than a day on that. I will try the latest DD-WRT build in a few days and let's see. _________________ WRT54G v6, WRT160N v3, WRT610N v2, E2500 v3, EA2700 v1

I will try adjusting the GTK re-key interval and see what sticks. Much appreciated _________________ WRT54G v6, WRT160N v3, WRT610N v2, E2500 v3, EA2700 v1

I did a bunch of testing and I think it was a mix of GTK re-key, some weird DNS issue and SFE (maybe) that affected the wireless only. I have DNSmasq as DHCP and DNS server. I lowered the group re-keying then turned off local DNS and had the DNS server advertised as a DHCP option, that kinda stopped the issue. And I stopped SFE. Combination of those worked and I didn't have to upgrade or downgrade. _________________ WRT54G v6, WRT160N v3, WRT610N v2, E2500 v3, EA2700 v1

DNSMasq is a tricky b*tch. On the basic setup page, I have force dns redirect selected. On the services page, I have rapid commit support selected. Everything else is default. The only extra options added are no-resolv and all 4 OpenDNS servers listed. That along with the GTK re-key interval set to 0 seems to be working for me with no disconnects and only a very random dns hiccup.

Thanks for suggesting the GTK rekey thing _________________ WRT54G v6, WRT160N v3, WRT610N v2, E2500 v3, EA2700 v1

It was suggested to me after I had been setting it to 99999. I'm guessing somewhere in the process of K3X testing and KRACK fixes, that function got broken. I don't have an issue with it being set to 3600 on FreshTomato.
. Any idea what might be causing those? Thanks!
