Hello meshies I know everybody is having fun at Battle Mesh, but if someone could take a look at this I' d really appreciate. I really have my eyes on the C50, as it seems to be the cheapest dual-band on the market now. I can get on in Brazil for less than 40 USD! Last week I bought one which I later found out to be an unsupported V2. But now I got a V1, and it almost works. If it works, I'll the buy about 10 for an installation in two weeks. The problem seems to be with 802.11. The 2.4Ghz radio does not work in ad-hoc mode - although the 5Ghz radio does. Then I don't know if it's related, but when it meshes with a WDR3500, the Internet is painfully slow, with some ping times about 1000-2000 milliseconds. Pinging from the LiMe gateway at the same time gives me a steady 57ms. Perhaps a different driver should be used? Attached is a file with information gathered from the router. A few other oddities (not as important as the issue above): - Could not flash from stock directly with the compiled LiMe. I had to first use this openwrt [1], then LiMe - When I flash from the firmware above with the LiMe I compiled or the download Lede, I get the message: " It appears that you try to flash an image that does not fit into the flash memory, please verify the image file! Size: 7.63 MB (7.62 MB available)" It works fine, tough. - The firmware I cooked with my community settings (using cooker) won't go through to the Internet, and gives this ESSID instead of my community's:{{NETWORK_NAME}} (although it meshes with the LiMe gateway) - The firmware I cooked without community settings connects to the Internet through the LiMe gateway with the sluggish times above.

[lime-users] TP-Link Archer C20 v4 and TL-WR840Nv5(ES) - any experience?

by Patricio Gibbs

On Monday night through Wednesday we have a training that includes setting up a 400 meter link (near Puyo, Ecuador, UTC-5). We have purchased a TP-Link Archer C20 v4. We plan to connect it via Nanostation2 and NanoLoco2 with a WR840Nv5(ES) that belongs to a small ISP (why this arrangement? combo of cheapest new and used hardware that I thought would work). The 840N only has 4MB RAM, which I understand is not really recommended for LibreMesh. Neither of the routers are on the list of devices at http://chef.libremesh.org/ for LibreMesh, but they are on the list for OpenWrt. The most similar device by name on the LibreMesh list is the Archer C20i. If we can LibreMesh-ify the ISPs 840N router in a way that it can easily be returned to factory firmware, maybe we will do that. If we can LibreMesh-ify the Archer C20 without a high probability of bricking it, we will do that (we don't have money in the budget for a replacement this week). I can use lime-sdk cooker instead of Chef -- I have done this before to test a new translation file. Suggestions on how to proceed? Here's the C20v4 data: https://openwrt.org/toh/hwdata/tp-link/tp-link_archer_c20_ac750_v4 Supported Current Rel: snapshot Unsupported Functions: WiFi 5GHz Target: ramips Subtarget: mt76x8 Package architecture: mipsel_24kc Bootloader: U-Boot CPU: MediaTek MT7628AN 8 MB flash, 64 MB RAM Compare to C20i: https://openwrt.org/toh/hwdata/tp-link/tp-link_archer_c20i_ac750_v1 Supported Current Rel: 17.01.4 Unsupported Functions: WiFi 5GHz Target: ramips Subtarget: mt7620 Package architecture: mipsel_24kc Bootloader: U-Boot CPU: MediaTek MT7620A 8 MB flash, 64 MB RAM TL-WR840N v5 (ES) -- belongs to the ISP https://wikidevi.com/wiki/TP-LINK_TL-WR840N_v5 CPU1: MediaTek MT7628N (575 MHz) FLA1: 4 MiB (GigaDevice GD25Q32B) RAM1: 64 MiB (ESMT M14D5121632A) ~ Pato

[lime-users] LiMe device compatibility and Chef

by Patricio Gibbs

Continuing my quest to categorize devices based on their LibreMesh compatibility, since the LibreRouter hasn't arrived yet and won't solve all needs.... 1) great, (e.g. WDR3500) 2) okay, but fixed antennas 3) some functions not working, (e.g. Archer C20v4) 4) emergencies only (ones that have 4 or 2 MB flash) 5) incompatible (e.g. 841HP) In Chef, when I type "ubiq" in the router model field, I get a list of Ubiquiti devices supposedly compatible with the latest release of LibreMesh. How is this list generated? Is it reviewed by a human? Here are examples of why I ask: it says Nano-M and Nano M XW: are these NanoStation or NanoBeam? It says Loco XW but the OpenWrt ToH says that the latest supported release for the Loco is 10.03.1, https://openwrt.org/toh/ubiquiti/nanostationm2....? Flashing LibreMesh onto NanoStation and TP-Link CPE devices could make some networks much easier to maintain.... If it actually works. This continues a conversation from last year about improving our documentation, such as maintaining a LibreMesh wiki. ~ Patricio

[lime-users] Current options of a captive portal for LiMe

by Amuza

Hello, Here we are considering again the captive portal thing. It would be a welcome page with some community news, not real authentication. I guess we would like a system where MAC addresses of users who just clicked an "Ok" button of the splash page would be validated for a month. So they would have to go through this News page once a month. I've seen Nodogsplash seems to be maintained again, so I can try to make it work for LiMe. But first I wanted to ask about Pitbull, as I think that was something similar but specially made for LiMe. What is the status of Pitbull? Would it work for the described need? Thank you!

[lime-users] Little steps in the good direction

by Amuza

Hey sisters, Let me share some good news for community networks -and bad ones for ISPs: 0.- Bitmessage has been working on LAN peer auto-discovery. It is already in v0.6 branch, we tested it and it works. 1.- Retroshare will finally have asynchronous messaging working (Retroshare already has LAN peer auto-discovery). 2.- Impressive ZeroNet is aware of the importance of LAN peer auto-discovery and they are going to add this feature.

[lime-users] replacing dnsmasq-dhcpv6 with odhcpd-ipv6only

by Paul Spooren

Hi, there are so many dnsmasq issues for LiMe[0] that I though to lower it's impact a bit. A first step to replace dnsmasq-dhcpv6 with the usually preinstalled odhcpd-ipv6 only, which should offer even more functionality. Therefore a small PR on GitHub[1]. Only drawback is for now, that IPv6 addresses are not distributed to other hosts when roaming, or more precisely, odhcpd-ipv6only doesn't accept adding leases manually. For now, Daniel Golle will likely fix this in the early future. I'd be happy if somebody could test this change, I compiled some targets on the snapshot server[2], if your favorite target is missing please ping me. Best, Paul [0]: https://github.com/libremesh/lime-packages/issues?utf8=%E2%9C%93&q=is%3Aiss… [1]: https://github.com/libremesh/lime-packages/pull/379 [2]: https://snapshots.libremesh.org/staging/aparcar/targets/

[lime-users] Backup power supply with network alert

by Patricio Gibbs

Has anyone set up a system that does this: When the public power grid cuts off, a backup power supply gives power to the node and a message is sent to the network saying "Main power cut off, switched to backup power." Then, when the power comes back on, a message is sent saying "Main power returned." I imagine a RaspberryPi could do this, but I don't know how, and I wonder if there are less expensive ways to do it. The messages could be sent to the gateway node in our community and stored on that router, or email or something else. This would help us because the power goes out about two times per week at our gateway node, but the only symptom we see is that our internet connection cuts off, and we don't know if it's because of power outage or ISP problems. We want to know, because this way we can make official complaints about the quality of service to the ISP, and we can decide how much backup battery power we need in order to enable continuous connectivity.

[lime-users] Testing LibreMesh based on OpenWrt 18.06.0-rc1

by Paul Spooren

Hi, on our snapshot server [0] you find LibreMesh builds based on OpenWrt 18.06.0-rc1[1] with packages of the development branch (master) of lime-packages[2]. The folder structure may change within the next days a bit. Many new devices are supported, if you can't find your device on the snapshot builder but it's supported, please report the device[3]! Please report issues on GitHub[4] and prefix the titles with "18.06-rc1: ".

[lime-users] using lime with single interface devices

by fauno

hi! we just installed lime_mini into our tplink wr841n v11 nodes, but we're a bit confused about the setup. it created three wifi on radio0, one is a mesh point and the two others are ap. but when we tried to disable the aps, the mesh wifi stopped working. first we disabled the config for the ap wifis on /etc/config/wireless and after `wifi off` and `wifi on`, the mesh point would be recreated but without an ssid. later we removed the 'ap' y 'apname' from /etc/config/lime and ran `lime-config`, which did the same we did manually, with the same results. what would be the config for just running mesh points? :D -- }(:=

[lime-users] Interesting dilemma - internet access from router shell

by Harri Nyman

I'm using self-cooked version of latest development LiMe, and I run across quite baffling problem. Routing through AP works fine, I can access internet normally and everything works - HOWEVER, if I log in to router and try accessing internet from router shell, using ssh/wget/opkg/whatever - nope, nothing works. Even ping does not work, although if I use workstation connected to AP and ping from there, without loggin into router, everything works as expected. What am I missing here? Harri
