Hello to all,

First of all I must say that I do not own any of them, but I've read a lot about both models and the things I've understand so far is(please correct me if I'm wrong):

TL-WDR7500 v1 - Qualcomm QCA9880-AR1A (v1) 8M which sucks because it will never be supported
TL-WDR7500 v2 - possible Qualcomm QCA9880-AR1A (v1) 8M
TL-WDR7500 v3 - QCA9880-BR4A (v2) 8M has the same almost the identical hardware as Archer C7 v2 with the only difference the flash being 8MB instead of 16MB and should be easily supported in future since Archer C7 v2 is supported.

Archer C7 v1 - QCA9880-AR1A (v1) 8M sucks as well because it will never get supported..
Archer C7 v2 - QCA9880-BR4A AND 16MB and has support

TL-WDR7500 being with Chinese interface and 6 external antennas and the Archer C7 with only 3 external(for ac) and 3 internal for N.

From what I understand AR1A is getting ditched by Qualcomm themselves and there are no drivers for them.

So the dilemma here clearly is whether to get the WDR-7500 v3 vs Archer C7 v2 now. They both support open-wrt currently so I guess it's safe to assume that they will soon get support for dd-wrt as well.

In fact there is a chinese seller on aliexpress offering the WDR-7500 v3 with open-wrt preinstalled.

The current price of WDR7500 is around $90 and the Archer C7 v2 around $120-130. (this is including shipping to my location)

Then it comes down to:

8M & 6 external antennas VS 16MB & 3x3 antennas

My questions are the following:

1. Are the 6 external antennas worth it? Will they significantly improve the signal more than the internal antennas?
2. Is the 16Mb flash going to be anything more beneficial than the 8Mb of the WDR7500 ? I've read some russian forums that suggest replacing the 8Mb chip with an 16Mb and then installing openwrt to that. I don't understand russian that well, so may I ask why are they suggesting upgrading it to 16Mb when open-wrt works on 8Mb well? Will this present any issue for installing dd-wrt as well?
3. Given that the WDR7500 v3 has the same hardware as the archer c7 v2 do you think that the current dd-wrt build can be installed on the WDR7500 v3 without issues?

These are some assumptions that I got from reading all around about those two routers so please feel free to correct me.

forget the chinese only models theyre usually nerfed in some way, like flash..the external antenna thing is garbage, theres many great routers with internals, theres many great routers with externals. the same for many crap ones of both variants.

u should do the following as well:

-go to the ftp link in my sig
-to the latest build
-search for "tplink_archer-c7-v2"
-be amazed

I own a WDR7500 (Chinese firmware). Does the DD-WRT for Archer C7-v2 work on it since the internals are almost the same?
