TL-ER5120 slow browsing, 1/10 download speed
Hardware Version :
Firmware Version :
ISP :
Hello,
I have three WANs connected to my TL-ER5120. WAN1 fiber optic 100 Mbs, Second WAN 4LTE 54 Mbs and the WAN3 4 Lte 54.
[/FONT]I have checked the load balance and then I check it out. [FONT=verdana]Enabled Application Optimized Routing. Web browsing with different browsers is not that much difference, slowish speed. Now downloading is really bad. Max 2 Mbs .
I connected one machine directly from the 100 Mbs modem and the download speed was up 12 Mbs !!!!!!!!
So I can confirm the TL-ER5120 does slow down the internet feed where I show have throughput 200 Mbs.
So, is the setting setting? what stupid setting am I doing?

I think you mention two different units: bit and Byte. When we talk about bandwidth, it refers to "bit" cause ISP usually tell us that. But when we download something like movie, it display download speed which is "Byte/s" unit. And remember 1 Byte= 8 bits. It's common science and people usually get confused about that. You should know this

Hello all
I have the exact same problem.
I use the TL-ER5120v3 to use 2 internet connection : ADSL connection (2mbps) and LTE connection (20mbps).
I can config the load balancing, and it works (i can see the IP of each internet connection if the first is down).
THe issue is : my download speed is really 1/10 ! But if i connect directly with wireless to my LTE router, i really have 20mbps.
Upgrading the firmware doesn't change anything.
Can you help ?
Regards

Hi, heres a solution that worked for me (Router 940N).
I had faced a similar problem with my new router 940N (450Mbps N-Router) when using with my BSNL-FTTH 50Mbps Fiber connection.
From the LAN on the router i could get >50Mbps but over Wi-Fi it was simply limited to a slower speed of 20Mbps for some reason.
I tried with multiple devices and they all showed the same slow speed of 20~25Mbps downloads/uploads.
I had contacted the TPLink Tech-support but could not get this solved over remote/Tele-call.
The next day after a few trials of my own I finally found the root-cause and solved it and its been working great since then.
The Solution that worked for me:
Since this is an N-Router, at the Wireless security settings, TP-Link Setup wizard itself recommends not to set TKIP Encryption but my BSNL technician did set TKIP wrongly during installation.
On finding this info from the Wireless Security settings page itself, I tried changing it back to the alternate option of AES.
Now here is the strange and funny part.
For some reason the Router though it showed the settings saved as AES, it seems it never was actually applied it. The speed was still slow at <20Mbps.
Now even after a hard-reset and fresh re-configuration of the Router with AES encryption settings, it did not work.
Then I tried disabling the "Security" itself first, on which I got >55Mbps speed and then next I set it to AES.
This time it seemed to have applied the settings correctly and the high speed was retained and i have never had the slow-speed issue again.
To confirm this fix i reproduced the steps of going with TKIP and Hard Reset etc and finally back to AES and it has proved to be correct.
Not sure if its a bug in the Router.
Anyway, for anybody facing this issue, please do try these steps. I was almost on the verge of returning my router via Amazon but managed to avoid doing it.
Best Regards,
Thomas
