However, as long as you don't need either crypto nor web-ui it should still be ok. The WiFi support for the MT76x8 WiSoCs is constantly improving, it's not as good ath9k yet, but getting there bit by bit. Regarding the C20, there is literally 0 hope for the 5GHz chip (MT7610E). Unless something miraculous happends, which is highly unlikely. The chip just sucks, the driver is crap and no FOSS driver is suitable to support it. 2.4GHz should work fine, but it's kind of a waste to run OpenWrt on those boxes... There have been several attempts of porting the crap-driver to OpenWrt, if you go through all the pain to build it (and it's vendor-specific user-land hostapd-replacement) it may be good enough to provide a single AP interface on 5GHz (but no mesh, no client, no interface- combinations, no bandwidth prediction, no ad-hoc, ...) Running LibreMesh with the crappy vendor driver would also be quite some effort even if that interface is only a plain AP...

Hi Parick. Here in Argentina I have bought several used routers in MercadoLibre for a really good price. Is not so difficult to find TL-WDR4300 (the best option), TL-WDR3600 or TL-WDR3500 between 650 and 900 Ar$ (26 to 36 Us$) with transportation included. I recommend the WDR4300 because in some cases you can use 2 of the 3 antennas in 5 GHz to establish 2 mesh links and the third one to use it like AP at 2,4 GHz in the roof of the house. We are running our mesh with this 3 routers + 1 WR841ND v6 and no issues with them and lime (except the one related with BMX6 that was resolved with an easy homemade workarround) Good luck :-) 10 de junio de 2018 9:55, "Patricio Gibbs" &lt;patricio(a)altermundi.net (mailto:%22Patricio%20Gibbs%22%20<patricio@altermundi.net>)> escribió: The 5 GHz doesn't really matter at this point since that device is only for client connections... Although LibreMesh on one router of a two-router network doesn't make a big difference, and flashing via TFTP (the only way for the C20) isn't the sort of thing I want to teach people, since it's a bit more complicated than flashing via a web interface. I think this training's software part will be about configuring Ubiquiti and TP-Link devices through their factory interfaces, and LibreMesh will wait until some other time. This is more in line with the economic and technical reality here anyways. Sounds like spending an extra $20 for a WDR3500 would have made sense, but the budget was tight and now it's too late to return the C20. There are only three WDR3500 for sale, so it's not like we're going to build many networks with them. The C7 is available for $110, but that's three times the price of a C20. I spent a while looking through MercadoLibre (the primary online market here, owned by eBay) and OpenWrt wiki and WikiDevi... Maybe someday we'll figure it an easier way to navigate all this information. This takes us back to the conversation from last year about how to improve our documentation. The 842 has a different chipset and bigger flash, looks ideal but it's not available here. Ooooooh, I say that, and I just checked again and there are five of them from a seller in another city for $39 each... Opportunity knocks! ~ Patrick El 10 de junio de 2018 7:20:33 GMT-05:00, bruno vianna &lt;bruno(a)pobox.com (mailto:bruno@pobox.com)> escribió: I don't know if it helps, but we have been running lime on a TP-Link TL-WR842N/ND v3 as gateway very smoothly.

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/ (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?
