Hi, I just bought a tp-link wr940n v6 and was contemplating openwrt, knowing that it has the 4/32mb. I saw, however that the latest iteration of wr841n (v13) is 8/64 with 580mhz MediaTek MT7628N. Should I return the wr940n v6 (4/32, 750 mhz Atheros TP9343) for the wr841n?
What sort of features apart from luci will I be missing if I keep the 4/32?
Is there any meaningful difference in the cpus if I don't run a vpn?
I want to stay at the 20 euro mark for this purchase and both of these qualify.
Thanks a lot!
I can't recommend a 4/32 device to a new OpenWRT user for much of anything, not to mention anything in the future. They're too small and too underpowered for general use. You can't run much more than wireless, basic routing and DHCP/DNS from dnsmasq on them. See https://openwrt.org/supported_devices/432_warning
While I don't have experience with the units, the WR940N is not one that I'd recommend.
See also, for further ideas and opinions, the (long) thread
atheros all the way, there are pending PR's that can enable the use of LUCI even on 4 MB, if ipv6 is disabled, if ipv6 is a must, then you must look for other things. but mediatek in wifi laks the stability of ath9k
Don't buy any 4/32 devices anymore please... Even if ath79 might be flashable on them in the future, any newer kernel or other software bumps would make OpenWrt choke on the 4 MB quickly enough again.

I'd say that 32Mbyte of RAM is also pushing it...
You get what you pay for...
In that range you're probably better off going to for a used unit.

I´ve created a minimal config for creating a ath79 image.
Should be easy to adopt this to a ar71xx image.
Notes for this config:
- no ppp/pppoe/...
- no opkg
- no dmesg
- no debugfs
- ...
You could use that as base and enable anything you need...
The resultant image size for wr841v7 with this config is 2.7 MB.

With this config as base i was able to add luci, openvpn-mbedtls and full wpad to a image for a 4mb device.
