Slow download speed on 2.4GHz on Archer A6
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello,
I have an Archer A6 router bought around 2 months back. It is connected to an FTTH modem with 100Mbps connection.
When connected to 5GHz wifi, I get connection speeds of 90-95 Mbps. However under the same circumstances (just switching the wifi), when I connect to 2.4GHz, I get a maximum speed of 40-45 Mbps. Upload is 90-95 Mbps in both cases. This behaviour is consistent.
I have a laptop with AC wifi adapter. The associated/lnk speed shows 520 Mbps when connected to 5Ghz and 144.4 Mbps on 2.4GHz.
The testing is done with the laptop a few meters away from the router and with no other device connected.
For 2.4GHz, Wi-fi mode is set to 802.11n only.
Channel and channel width are set to Auto. Tried several options with no difference in behaviour.
Security/encryption is set to WPA2-PSK AES.
Negotiation speed shows 100Mbps full duplex.
WMM and Short GI are enabled.
MU Mimo is disabled.
Tried disabling NAT Boost. No difference.
Shouldn't I be getting simiar speeds on a 100Mbps connection on both 2.4GHz and 5GHz wireless? Or is my understanding/expectation wrong?
I have checked several threads which mention similar issues; however found no working solution except downgrading to firmware version 1.3. Anyone has had the same problem and resolved it ?

Thanks for the inputs.
Had tried with several laptops. The problem persists.
Also had raised a support ticket several days back. Still waiting for their response.

@BS11 you're not alone, im having problems with my Archer A6 ac1200 right now. Ive tried EVERYTHING. My older single band router wr840n works better than my new one. The problem exists in the last 2 weeks, i thought my service provider has issues but when i used my older router, i found out that A6 is faulty. I dont know what to do. Is it a hardware issue or software? Please respond.

There's a beta FW for your device targeted to solve some of the wi-fi issues.
You can give it a try and see if it helps. You can always revert back to the latest official FW if beta doesn't help.
Refer to this thread for downloading the FW in question - Kevin's second post.
Keep in mind that the FW is a region dependent, so download the appropriate file from that post.

@terziyski I'll try that later. Even with wired connection the speed is annoying. From 80-90mbps dl rate, it went down to 9mbps and 2mbps UL with Archer A6.

@BS11 update on my archer a6 ac1200. I downgraded to 1.1.5 Build 20191112 rel. 36515 (5553) from 2020 *ish, so far its doing fine on internet speed since i rebooted the router twice along with its "lag" while logging in to its webui. I haven't tried the beta FW yet fearing that it might disrupt my zen and peace.
Edit: I rebooted my archer a6 ac1200 for the third time AND it went back to being a head ache again and my moms phone can't connect via wifi. Smh.

when i tried the beta it says Invalid File type for my archer A6 ac1200 v2.
I downgraded again to 1.1.5 Build 20191112 rel. 36515 (5553)
so frustrating.

If you downloaded the file from the second link, then try the third one. C6/A6US...
On the bottom of the device you should have printed your region, I believe it's US (not an EU) so the third link is the correct file.
Make sure your wireless settings are :
Disable OneMesh and NAT Boost and test to see if any difference.
