Model: ER707-M2  
Hardware Version: V1
Firmware Version: 1.2.2 Build 20240324 Rel.42799

Don't know why I can't select the version from the dropdowns. But it is a ER707-M2, hardware v 1.2, firmware 1.2.2 Build 20240324 Rel.42799

 

I recently upgraded my home internet speeds to 2 gbit, and purchased this router to complement it. It seems to work reliably, but I have only been able to achieve ~200 mbps download speeds on all my devices, and about 300 mbps upload speeds. The upload limit is expected as that is what my ISP supports. But I used to get ~800 mbps download on my old cisco router when I had only a 1 mbit plan.

 

I made an appointment with the ISP to fix this, but then I purchased a 2.5gbit usb network adapter, and to my surprise, I get > 2 gbit download speeds with that adapter. So I assume this is a router issue and not a ISP issue. The odd thing is that when I unplug the SAME CABLE from my 2 gbit adapter and plug it into a 1 gbit ethernet adapter on the computer, I get only about 200 mbps. So it is not a cable quality issue. It isn't just one computer, all of my other devices have gigabit ethernet adapters and they all get only 200 mbps downloads. In addition, all the 1000 mbps ports on the EA707 only deliver 200 mbps downloads. 

 

However I did perform some large file transfers internally, and one time I think I got 800 mbps speed, but other times only around ~200 mpbs. 

 

The EA707 seems to work perfectly otherwise. And my ISP is clearly able to deliver >2gbit speeds. So I would guess this is some sort of firmware/software/config issue with the EA707. 

 

Any idea what I can do to fix this?  

 

Thanks

Kahn

Thank you. 

 

I had considered updating the firmware, but was unsure which version matched my hardware (the UN lablel is not in the hardware).

 

Anyway, after the firmware update, the gigabit speeds are much better! I did have a scary moment after the update when the router would not restart. Unfortunately I needed to do a hard reset to get it going again, but had the settings backedup, so it was no problem in the end.

 

Thank you for your reply.

Good to know.

The restart might take longer than usual compared to the home routers. That's expected. No worries.

enable Flow Control on the WAN port.  Also update the firmware to the version Clive indicated.

 

On multi-gigabit WAN connections TP-Link routers need flow control enabled WAN side to achieve the maximum potential speed.  This is also the case with the ER8411

Main: ER8411 x1, SG3428X x1, SG3452 x1, SG2428LP x1, SG3210 x1, SG2218P x1, SG2008P x3, ES208G x1, EAP650 x6 Remote: ER7206 v2 x1, ER605 v2 x3, SG2008P x2, EAP650 x2, ES205G x1 Controller: OC300

  @GRL Thank you.

 

The firmware update did the trick. I didn't make any other adjustments, and probably won't as it is working OK now.

 

But for curriosity sake, why is "flow control" needed/how does it work, and where is it in the settings. I see Rate Control under Network:Switch and Bandwidth Control under Transmission. 

 

Looking at Bandwidth Control, I can select "Enable Bandwidth Control", but doing that cuts my download speeds by more than half. 

 

Anyway, just curions, as I am happy with the performance with the new firmware.

Standalone Mode

Network > Switch > Port Config Tab , enable it for whichever your WAN port is

 

In controller its on the port config of the gateway device > config tab

 

 

Flow control makes sure that buffers dont get saturated and insert control frames if a buffer is nearly full.  For some reason, this actually improves multi-gig performance on TP link routers  (i get an extra 500 ish mbit by enabling it on ER8411 on the test bench i have here)

Main: ER8411 x1, SG3428X x1, SG3452 x1, SG2428LP x1, SG3210 x1, SG2218P x1, SG2008P x3, ES208G x1, EAP650 x6 Remote: ER7206 v2 x1, ER605 v2 x3, SG2008P x2, EAP650 x2, ES205G x1 Controller: OC300

  @GRL 

Oh, I must be blind. Thanks. 

Do I just enable it on the 2.5 gbit ports (1 and 2), or only the WAN port (1), or all of them? Of course I can play around with it but just wondering what best practice is. 

 

[Edit] I see you said just WAN port now that I read more closely. Thanks!

just whichever is the WAN port.  If it makes no difference or slows it down, you can just turn it off again
