I am asking if people have had any issues with any of the 5 hardware versions, the later versions have better CPU and Memory but sometimes one does not find the issues till after.?
Apart from v1, all of them should be reasonable to use - obviously more flash (v4, v5) is better, but so would be 128 MB RAM and a second (5 GHz) radio; that said, you're unlikely to find anything but v5 in the current market anymore.
But I'd still like to echo Bartvz and suggest a more reasonable device for buying in 2021 (concurrent dual-band, more flash/ RAM - and 802.11ac instead of 802.11n); mt7621 and ipq40xx come to mind.
Thanks for clarifying Peter, that is the thing, I am a total newb, I have a specific application and with the 1043 it just works, performance is ok but with two superior routers I tried they just do not work.
So when getting one for a friend I know I can backup mine and copy to another and it will just work, I may even give them mine and start with the hopefully better one.
I think I have a V2, it cost me less than a couple of cups of coffee, I have seen several on eBay for various prices but not that cheap. I will probably hold out until a V5 comes along, currently most are V1 and a few V3.
I have bought other Routers only to find that they have issues with OpenWrt or they just do not work, so I am going to put them back on eBay and treat myself to a decent 2nd hand router.
The R7800 seems good but their prices have gone through the roof, mad prices being paid.
