Archer A6 v4 - Speed seems to be limited
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi, I need some help with my Archer A6.
I have an internet connection contracted with a fiber optic internet service provider at a speed of 1000mbps.
However, the provided modem is poor and the Wi-Fi doesn't reach my office (pratically next door). That's why I bought an Archer A6 router and used a CAT6 cable to bring the internet to it (its sitting right next to my computers), but the internet on the 5GHz Wi-Fi is reaching a maximum of 250mbps. Even the graphic at a speed test looks like it has no fluctuations and is stuck at 250...
When I connect the same cable to one of my computers directly, it can achieve speeds that exceeds 500mbps, which indicates that the router is limiting the speed, correct?
Is there a solution to it?
Thanks, anyway
Hi @juliomelo91
Firstly, we need to understand that Wi-Fi works in half duplex mode, which means that half of the bandwidth is being used for receiving data while the other is being used for transmitting data. Plus, we have to remember about interference of the Wi-Fi signal, which can also cause problems with speed and overall Wi-Fi quality.
You can use the following formula to calculate the approximate maximum internet speed that you can get via Wi-Fi:
(a — link speed or maximum bandwidth; b — approximate maximum internet speed; 20% is the approximate value of the speed we lose due to signal interference)
According to Archer A6 specifications, maximum bandwidth at 5GHz is 867 Mbps, which is approximately up to 400 Mbps internet speed in a perfect circumstances.
So, back to the main question, could you please tell whether this issue occurs on all devices or only on some specific devices?
What's the link speed (you can see it connection info) while connecting to the 5GHz network?
Have you tried doing the speed test while connecting to the router via Ethernet cable? What were the results?
