Router Model: Linksys WRT1900ACSv2
Firmware Version: DD-WRT v3.0-r33986 std (12/04/17)
Kernel Version: Linux 4.9.66 #80 SMP Fri Dec 1 06:24:04 CET 2017 armv7l

Uptime @ 1 day, 12 hours

Running with OpenVPN Client enabled.
OpenVPN speed is nothing to complain about.(native 250/100 connection)



Very stable firmware so far. No issues.

My WRT3200ACM isn't really keen on this build.

The problem seems to do with letting Android devices and Chromecasts (which are also Android based?) use the WiFi. iOS devices and computers (Windows, macOS and Linux) connect without effort.

I have tried various settings with both radios. And a complete reset. Didn't reset nvram, but isn't that technically the same as wiping the settings while writing the firmware to the router?

I am not positive, but something points towards ath1 being more uncooperative than ath0.

One example of a Chromecast (2.4 GHz) trying to connect yields these lines.

Does this built use the WRT1900ACS v1 to its full potential? This is the first time I'll be trying DDWRT on this router and I want to make sure the wired LAN and wireless LAN speeds aren't effected. One of the main reasons I'm going to try this is to unlock channels 140+ on the 5Ghz band.

I'm having almost identical issues to piju with my three Chromecasts.

Do you happen to have a link to any discussion/development on that so I could potentially follow progress?

I am wondering if anyone else here has issues with their WRT1900AC v1 and 5ghz on Apple products?

I am unable to connect any of our ipads or iphones to our wrt1900ac v1 using 5ghz. They all have the same issue and it just wont connect. They all connect to our ISP routers 5ghz fine though and I can connect all my other devices to 5ghz on my wrt1900ac v1, its only apple products.

Is this a known issue perhaps?

Check out the Advanced Wireless Settings links (there are two) in the Tutorial Sticky. They give a brief explanation of each setting.

All my Wireless Devices have 802.11n or 'newer' so I don't need previous versions.

You don't need to use Dynamic for channel width. Any device that doesn't support a higher width will connect at the maximum supported.
I believe it's an outdated setting.

I would set the Channel Width to 80 MHz and watch for send and receive errors. If you start to get too many (hundreds of thousands +) then go to 40 MHz.

Single User Beamforming is the predecessor to MU-MIMO (Multi-user, Multiple-Input & Multiple-Output).
My router is older and doesn't have MU-MIMO.

The way I understand Sensitivity Range is that it's only important when using a multiple router configuration such as WDS or Repeater. It would need to be set at twice the distance between the two routers (once for send & once for receive).

Strange issues with r33986 on my 3200 today.

1) It suddenly lost its active OpenVPN client connection. While I was in the GUI checking activity. Did have syslog & klogd running but I don't know enough to interpret the log messages.

So I rebooted it from the GUI. Reboot went ok. But =

2) After I rebooted the router & looked at the Syslog, the times shown in the syslog are strange Or is it actually January 1st already.

Any ideas on what happened? particularly why the times in the log are now messed up? Wonder about doing a complete shutdown & restart? Would that do anything different than just rebooting?

I was about to install the latest build r34080 today. But haven't done it because of these anomalies. And I've seen posts on r34080 about issues accessing its GUI.

This router is only running wired connections = WiFi is turned off. And it is the second tier of my router stack. It had been running reliably with everything going thru the OpenVPN client for a long time now with the newer builds.

Also, I monitor the router uptime and have not seen any power outages or Up-Time discrepancies that might have caused issues. And my router stack is on 24/7 and has its own UPS system.

Delete wrong thread.

For the Time Settings use pool.ntp.org. It will use the closest time server which should update the time a bit quicker.

Oops replied to a now deleted Myersw post. Guess that post was not intended in answer to my above post??

But the symptoms he mentioned were similar to what I was seeing.

Sam

my previous post to Myersw now removed post:
Guessing that your reply above is to my post. Are you suggesting that I should set dd-wrt to reboot periodically at regular times? ? weekly, daily, ?

With my connection to PIA thru Ovpn client, the Ovpn log shows reconnect every hour with PIA. But the client lease time is 1440 min. [Network Address Server Settings (DHCP)]. ?? Not sure how that might apply to this issue?

Are there other settings that could be contributing? You mentioned DNSMASQ how does that factor in?

And yes there were connect issues, ping did not work. And the IP checks that I regularly do were inconsistent eventually all showing my ISP IP address. There had been some activity from the PC connected to this router last night =no issues then. Since this router with its VPN is still being tested, only 1 PC uses it * that use is only occasional.

AS I say in my sig this router is in the 2nd tier of my router stack and it is set to a fixed static Wan-side IP within the subnet range of the main router.

Thanks for your help.
