After 3 days uptime, my samsung note 2 cannot reach wan though it links through wl0 and wl1 fine. The strange thing is my note 3 ok with wan. Everything backs to normal after rebooting.
In the interest of finding the cause of the dropped clients issue, could extra statements be added to Syslog to help diagnose this? Yesterday when all my wireless clients dropped on my R8500, it was right after adding a new iPhone to my 2.4 Ghz wireless so unless that was coincidence, I'm suspecting that something is happening when a new client connects that could cause a lockup in the wireless if something goes wrong.
All clients were still connected but couldn't transmit or receive any data as far as I could tell. Nothing in Syslog and the Tx/Rx errors were not increasing. It was as if the wireless interface was just "brain dead", so I'm wondering if some sort of check could be added or some statement could be added that monitors wireless clients and could detect when data passthru stops? I'm thinking some sort of authentication error must be happening that is non-recoverable. I don't know whether it's at the kernel level, wireless interface level, or what but maybe there's a way to pass that error forward into the Syslog so we can see what caused the brain death?
Edit: Do you think some sort of "verbose" Syslog option would be possible where kernel messages are passed through to the Syslog? And if Syslog gets too big from that, just limit Syslog to the most recent <however many kB>? I think that might be helpful as Syslog currently logs almost nothing: mostly just repeated dnsmasq acks and requests.
Uh oh. After about 4 days of uptime, my R8500 just dropped all wireless clients again. My daughter was having a party and complained that our Amazon Echo was brain dead. That was my cue. I checked Blue Iris and sure enough, all eight security cameras said "No signal" and no data was going through the 2.4 or 5 Ghz wireless devices. They were all still connected, just no data... like the previous version.
I did check Syslog just before I rebooted it (which fixed it). As usual, nothing in there but the typical dnsmasq entries: discover, acks, and requests. Now, just before this happened, one of her party guests asked me to type in the 2.4 Ghz password for her iPhone. Right after I did that and her iPhone connected is when this happened. Don't know if it was coincidence or that spurred the problem. That's all the data I was able to gather this time.

We are running the same build on different hardware, On my R7000 WiFi Router it currently has over 4 days & 18 hours of uptime with 8 SSIDs without any issues so far. I'm leaning toward the R8500's radio drivers as being an issue than the kernel. Did you change anything from the default radio settings? Myself the only changes I made was enabling "Implicit Beamforming" on both wl0 & wl1; plus on one vwlan wl0.3, the guest wifi, I enabled "AP Isolation".
So far for me this build has been as stable as the latest Kernal 3.x. _________________ Home Network on Telus 1Gb PureFibre - 10GbE Copper Backbone

tried every reset technique , Wifi 2.4 and 5ghz still has same MAC, i just fix this using MAC cloning feature of DDWRT
Thank you sir.

Linksys EA 6900 (XvortexCFE) has the same problem
But after resetting with WPS button (but not from GUI or from erase nvram), I have the correct MAC addresses.
I do not know if you can reset with the WPS button (press WPS button, unplug, wait 10 sec, restore power and wait 25-30 seconds (on linksys the router starts flashing after approx 25 sec)), but it is worth a try

2.4ghz and 5ghz MACadd is the same, is this normal for DDWRT?
Just notice this because my son new phone which is connected to 5ghz channel always disconnects then connect then disconnects almost every second.
by changing the MAC of 2.4ghz just to make it different fix the problem.
I tried flashing the default firmware and it shows different Macs for each band.

Prior to flashing I tested my 5GHz and was getting a steady 170-180Mbs, but after flashing I max out around 50-60Mbs. Less than ⅓ the speed I was getting. Any suggestions? Or settings that I should change? Thanks!

Nothing special. The only thing I changed was turning on explicit beamforming (implicit is off). This latest version seems better than previous but it still seems like there's a "hole" there somewhere which occasionally can cause dropped clients and inability to reconnect. All I can do now is wait for it to happen again and when it happens, I go through the status pages to see if I can see any clues. So far, there's nothing in the web GUI to indicate anything is wrong. Clients still show connected but as far as the clients are concerned, they are not connected (connection error).

After 90 days of uptime I believe it is time to do an update with this new version.
Can I backup my settings in "Administration -> Backup" and restore it after the update?
Or is it best to do all settings by hand again?
I am asking because I have many MAC+IP binded, port forwardings,.... and an easy way to restore after every update would be nice
It's best to do it by hand. You should never upload a backup to a build it wasn't made on. An NVRAM variable could have changed/been added/removed that will brick your router or at least make it unresponsive. If you upgrade, always reset and re-enter settings if you wanna go the reset route. _________________ Deployed Routers:

ciscodlink,
the question of do I backup or manually reconfig has been hit ad nauseam.
In the R7000 tip/tricks sticky is a link for how to use a backup script where you can customize exactly what you want backed up.
Using it as a template you can even figure out how to do it manually and once you have it down in a text sheet the first time, pasting the commands in at the command prompt can take less than 5 minutes.
Kong has suggested on multiple occassions that he suggests the average user just reconfig from scratch since you might import something that is going to cause an issue in newer code; however Kong has also in the past notified everyone when a reset to default is required do some command structure change in new code.
Most of the time a dirty upgrade is fine. If it acts up, then you should try a manual reconfig.

EDIT: opkg's nano package no longer works. Dunno if that's something to mention or not. lol _________________ Deployed Routers:

One of the internal library nano has dependency on seems to be broken. In the mean time, before Kong fixes it, you can just install that particular package (package name is in the error message) and set up a symlink to point to that binary (in the appropriate /bin directory nano is looking in).

R7000, encountered an issue. After 5-6 days of working fine, the router suddenly refused connections via wifi on both normal SSID and guests. The WAN and LAN connections dropped as well, could not connect to the internet nor access the router via web. However the router was accessible via telnet, and managed to reboot it through commands.
So far after 5 days all is working. I do have 2 wireless device that are connected at all times and they have a connection uptime of over 5 days and 16 hours.
I haven't lost Internet connection plus I have multiple VPN connections and radio & TV streaming has been all working fine so far. _________________ Home Network on Telus 1Gb PureFibre - 10GbE Copper Backbone

I found one bug:
If connected to a VPN, changes in the DMZ page kill the connection for all clients.
A restart of the VPN service is necessary to regain external net access.
Device: R7000
Update from a very old build, with power cycle and reset and nvram erase....
