Upgraded router, signal is the same but speed at distance sucks

[BeHapptFTW]

I upgraded from a TL-WR940N v1 to an archer c2 ac750. I expected it to be better. To my dissapointment, i did a test at my room. Old router pulled 10-13 mbps but the new one only 3mbps max avrg of 1.2 mbps. (Same signal strength) both with 2.4ghz. Should i just buy the v3 of the tl-wr940n or my settings are wonky?
(Btw i am changing because old one is almost dead)

I suggest some additional testing first. Try different channels and even 5.0 GHz.

Have you contacted your ISP and let them run their tests while the new router is in place?

Try relocating/re-orienting the antennas. Temporarily raise the router a bit higher or move it to a couple of other places within a few feet.

Doublecheck all router and network adapter settings. Make sure they are all matched. Especially on the computer's network adapters: manually set speed and duplex versus any "auto" setting. Or if already set then try "auto" settings. Although there are standards some devices just do not play well together when it comes to handshaking and subsequent performance.

Sometimes a network needs "time" to reset itself when a new device has been introduced. All sorts of things are going on in the background and after a bit all the handshaking, tables etc. are again in good order. If you have a mixed environment (e.g.,multiple devices, differing Operating Systems) it may take a while longer to accomplish.

Even though you are using wireless check all physical connections as well. Try other known working ethernet cables. All should be snug and secure. Something may be been bumped, moved, twisted during the router swap.

Check the Archer router's logs to see what entries may have been recorded.

The additional testing will probably prove to be worthwhile. Overall you will learn more about your network and something may turn up.

Pretty good chance that if you buy the v3 you could have the same problem. Try to pin down the source of the slowness.
