Just an FYI, watch the wifi drivers- defaulted to dd-wrt vs vanilla on this nightly build.

Test (bridged) VAPs. If they don't work on Atheros, Marvell, Ralink/MediaTek, then we have a regression caused by a Broadcom fix. Also test unbridged VAPs. Test VAPs in general.

worky fine on EA8500 ... NO revert to DD-WRT.
Both Radios still on VANILLA
AND
I have VAPs on both + 1 wired port via br1 --- isolated net + they use different DNS...
...main net uses unbound Twisted Evil

Thanks for the info, @mrjcd. Maybe we can finally put the Broadcom VAP issue to a rest in the next public release Cool

That would be very nice. Very Happy

just so ya know:
but really ain't got nothing to do with bringing the VAP up/down

startup:
Code:
swconfig dev eth0 vlan 1 set ports "0t 1 2 3"
swconfig dev eth0 vlan 4 set ports "0t 4"
swconfig dev eth0 set enable_vlan 4
swconfig dev eth0 set apply
vconfig add eth0 4
ifconfig vlan4 up
brctl addif br1 vlan4
sleep 10
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] || continue; echo -n ondemand > $CPUFREQ; done
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor


firewall:
Code:
iptables -t nat -A POSTROUTING -s 10.172.128.240/28 -j MASQUERADE
iptables -I INPUT -i br1 -m state --state NEW -j DROP
iptables -I INPUT -i br1 -p udp -m multiport --dports 53,67 -j ACCEPT
iptables -I FORWARD -i br1 -o br0 -m state --state NEW -j DROP
iptables -I FORWARD -i br1 -o br0 -d 10.72.28.1 -m state --state NEW -j ACCEPT


yeahuh, in 'startup commands' I just let'er catch a breath before scaling back on CPUs
AND
1st firewall line is for her OVPN server
4th firewall just so those on br1 can reach the webserver

all has been the same for long long long time Twisted Evil

How are speedtests looking?

https://www.waveform.com/tools/bufferbloat

on wired I am noticing 3x as much latency on 47791 vs. 47762

I am also noticing that wifi performance on vanilla is not so good.... R7800

I have a feeling comcast in my area must be having issues.... reverted to 47762 and similar performance issues.... maybe the cold weather is affecting some surface equipment that is freezing...it rained yesterday and now 19 in chicago....

They have their own issues with DSCP and other bits an pieces affecting throughput. There's a wiki article that was written for Broadcom devices, but it's not a hardware-specific anything. And it's not just Comcast, it's most cable internet providers. Not sure if the TOS/DSCP firewall option mitigates this or not.

well shitfire now you made me doit

I just clicked the radio SFE button to 'Enable'
clicked 'Save' -- all ok
clicked 'Apply Settings' ---> things went to heck then.
Not reachable by any means at all.

NOTE: this is on the EA8500 switch (r47791)
The only thing currently behind it is 'daDeb' ---> main machine I use.
'daDeb' is NOT reachable either Mad and I was just about to rsync todays junk from it to my laptop.
Damnit I'll have to crawl out of this nice warm recliner and go see whatthehell.

I'll get back with ya in a bit I reckon...

may also be due to the fact that SFE is not compatible with unbridged VAPs.
I don't know if this has changed in the meantime, but it used to be that SFE was deactivated when unbridged VAPs were configured.

I don't use SFE myself so I don't know the current status.

so test VAP's and SFE at the same time - sounds promising

the EA8500 I done that on is just used as a switch.
both radios off
WAN disabled
NO vlan
it does have OVPN server
has 2 ext4 flash drives attached as samba shares

I also know that SFE don't make no nevermind on a switch but it is just something I can try things on cause it is NO big thang iffin I break it.

I can NOT tinker like that on main gateway EA8500
