Clients in same WLAN can't reach each other - Installing and Using OpenWrt / Network and Wireless Configuration - OpenWrt Forum
Q: Ethernet switch + 2.4G Wifi + 5G Wifi is bridged into one interface and firewall zone (lan).
I updated to LEDE 17.01.0 (stable) and got following problem:
Clients connected to the same Wifi SSID can not communicate with each other (same interface/firewall zone)
PING OPO.lan (192.168.0.17) 56(84) bytes of data. From MJ.lan (192.168.0.58) icmp_seq=1 Destination Host Unreachable ...
I can still reach it from Ethernet or from the other WLAN (5G -> 2.4G and vice versa) but not when both are connected to the same... It works fine if i create 2 different SSIDs on an adapter and put a client in each one.
Multiple clients connected through ethernet can also reach all others.

(Solved) Flaky wifi with WRT1900ACS v2 and Android phones - Installing and Using OpenWrt - OpenWrt Forum
Q: I have a wrt1900acs v2 running the latest wifi drivers packaged by @eduperez and it is giving me nothing but problems.

Specifically my Android phones simply refuse to stay connected. Recently it's gotten to the point where it hardly will even connect at all and I've turned it off so that my older tp-link devices are the only APs. We've had hot weather, and I wonder if that's relevant because it was never this bad before.

Rebooting the WRT device seems to fix the problem for a few hours. [...]

OpenWrt Project: Upgrading OpenWrt firmware via LuCI and CLI
An OpenWrt upgrade will replace the entire current OpenWrt installation with a new version. This includes the Linux kernel, the SquashFS partition and the JFFS2 partition.

The common upgrade paths below will automatically preserve much of the OpenWrt OS configuration by saving and then restoring configuration files in specific common locations (including /etc/config). This will preserve things like OpenWrt network settings, WiFi settings, the device hostname, and so on.

OpenWrt Project: Serial Console
Most people get along without a serial console for their device because they're able to flash a working firmware the first time - or are able to apply various recovery methods - and do all their communicating with the device over a network. However, some bootloaders don't have a “really failsafe” network re-flash feature, making a serial console one of the few ways to recover from a “bad flash” or an error in a user's own configuration.

Setting up wireless roaming using 802.11r fast transition on OpenWRT · morph027
Ages ago, i was setting up 802.11r the complicated way using all the r0kh and r1kh lists across all access points, which worked well but was a little pita to setup.

After creating a little helper, i just discovered that recent OpenWRT builds can cope with the option ft_psk_generate_local to dynamically create the RADIUS keys and stuff. Even with Luci support, just enable 802.11r Fast Transition and Generate PMK locally, set a Mobility Domain (same across all AP’s per SSID) and a NAS ID (unique, i’d still prefer the BSSID w/o the colons) and it works out of the box.

Finally got 802.11r roaming working : openwrt
[edit] Since people still find this post for advice, I'll quickly add a few notes.

Configuration has been vastly simplified with a recent OpenWRT release. Basically all you need is the following:

option mobility_domain 'e612' #same for all APs
option ieee80211r '1'
option ft_psk_generate_local '1'
option nasid 'xxxxxxxx' # different for all APs, AFAIK it will automatically derived from the MAC Address if omitted.

All this is availably via LuCI, go to "Wireless Security", enable "802.11r Fast Transition", enable "Generate PMK locally", that should be it. Unfortunately I lack the time and hardware to really test this. [...]

WireGuard is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPSec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it plans to be cross-platform and widely deployable.

OpenWrt Project: Dumb AP / Access Point Only
This document describes how to create an Access Point (AP) that extends a network that already has a router, access control, and DHCP in place. People can connect over wireless or Ethernet to the new AP and then to the existing network. In this configuration, the AP is not routing packets, it does not provide DHCP or other functions. The result is a bridged LAN (no internal subnets) that will work fine for home and small networks.

OpenWrt Project: Failsafe Mode, Factory Reset, and Recovery Mode
OpenWrt offers several ways to “start over” with your router.

* Failsafe Mode is useful if you have lost control of your device, and it has become inaccessible, perhaps through a configuration error. It allows you to reboot the router into a basic operating state, retaining all your packages and (most) settings. (see Failsafe Mode)
* Factory Reset erases all your packages and settings, returning the router to its initial state after installing OpenWrt. (see Factory Reset)
* Recovery Mode allows you to install new firmware on a router that has become corrupted. (see Recovery Mode)

Every operating system requires

1. Sufficient Flash to accommodate firmware image
2. Sufficient RAM for stable operation

Devices with ≤4MB flash and/or ≤32MB ram will work but they will be very limited (usually they can't install or run additional packages) because they have low RAM and flash space. Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported.

The following preparation is recommended, before flashing OpenWrt/LEDE firmware:

* Don't rush the installation, take your time. If something seems weird during installation, find answers first before continuing.
* Have your device's precise model name at hand (so you are able to select the correct OpenWrt/LEDE firmware)
* Have your devices's documentation at hand, on how to flash new firmware
* When installing and configuring OpenWrt/LEDE on your Internet router, your Internet-access will obviously be offline for a few minutes. Please ensure that you have all required information offline or have backup Internet access at hand in this time.

Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Open Wireless Movement
Imagine a future with ubiquitous open Internet.

We envision a world where, in any urban environment:

* Dozens of open networks are available at your fingertips.
* Tablets, watches, and other new devices can automatically join these networks to do nifty things.
* The societal expectation is one of sharing, and, as a result, wireless Internet is more efficient.
* The false notion that an IP address could be used as a sole identifier is finally a thing of the past, creating a privacy-enhancing norm of shared networks.

We're working with a coalition of volunteer engineers to build technologies that will let users open their wireless networks without compromising their security or sacrificing bandwidth. And we're working with advocates to help change the way people and businesses think about Internet service.
