Bug
Freshly setup Linksys EA8300 to latest stable release. WiFi Issue with my two (older) apple devices on the 2.4 GhZ WiFi. Devices are Mac circa 2013 and Iphone circa 2019. All Windows/Linux devices have no issues on the WiFi. The apple devices can see the WiFi, connect to it, but cannot actually see anything on the internet while connected. They don't ever disconnect/drop from the WiFi and are visible as devices on Luci. I’m not an Apple person so the test for internet connection is simply trying to reach websites via the browser.
OpenWrt version
24.10.5
Setup
First time setup on EA8300 via Luci. Setup requires V23.05.00 first, then update to router config via SSH, then installed latest stable release. Process here if needed https://openwrt.org/toh/linksys/ea8300
Here’s all I did on my device:
Login (all work below via LUCI)
changed LAN IP from default
Set administrator password
installed software: advanced reboot, adguard lite, sysupgrade, and irqbalance
(Note adguard lite was disabled from boot, stopped, and router rebooted to confirm it wasn’t causing this issue. I even switched to another partition that never had adguard lite installed, didn’t help.)
Setup 2.4 GHTz and 5 GHTz radios onto new guest interface. Guest interface intended to be ‘Guest Network’ IE clients only have access to Internet and neither each other, nor the local network. Guest network allows traffic on port 53 for IPv4 and IPv6 and on port 67 for IPV4 and IPV6 via UDP.
Wireless-→Network then edit for the 2.4 GHz radio set to whatever settings desired for security etc.
Did the same for one of the 2 5 GHz radios but they're not relevant to the issue.
What I've Tried
Trying to keep this short, a version of this issue appears to be common see links below for related ones I’ve been reading. Based on said links, below is all the configuration changes I’ve tried. Between setting changes I shut the devices wi-fi off and turned it back on. I occasionally would forget the network and re-add it but I didn’t do that every time, only on the settings I thought most likely to work. The thing that confuses me the most is that, neither device could connect to the internet even when I set the channel to unencrypted. Some configurations they could no longer connect to the WiFi but usually they could still connect to WiFi but not the internet. Both devices work as I can go back to my original router (on OEM firmware, different hardware) and they can get to the internet just fine.
All of the these settings are found in Network→Wireless then edit for the 2.4 GHz radio I’m using.
Operating Frequency:
I’ve tried mode N and legacy
With N I’ve tried most configurations with width always at 20MHZ
I’ve enabled/disabled “Allow Legacy 802.11b rates”
WMM Mode I’ve tried on and off, typically leave it on now.
Encryption: I’ve tried every encryption combination on here I can including unencrypted. The links have consensus around WPA2 alone (NOT mixed) being the desired choice so it’s my usual choice. (Note the oldest MAC says it uses “WPA2-Personal” if that helps anyone)
802.11w Management Frame Protection- supposedly must be set to “Optional” (defaults is disabled)
Disable Inactive Pulling is disabled- One source insisted this was required, no one else said anything about it.
Isolate Clients is enabled, this is not for the bug but intended ‘guest’ network function.
Disassociate On Low Acknowledgement is disabled
802.11r Fast Transition “Roaming” was disabled by default and I didn’t touch it, lot of people said this was a huge issue if enabled but doesn't apply?
I'm out of ideas, does anyone have any thoughts?
