Hardware Version: V2
Firmware Version: 2.2.5 Build 20240522 Rel.75860

 

Hello,


I have 2 WAN connections, Telekom DSL 100 Mbit and Star Link connected via the ER605 v2.0. This is working so far. Now I would like to sort the WAN connections according to priority. The data traffic should primarily run via the DSL connection. If the 100 Mbit
are fully utilized, then further data traffic should run via the Star link connection.


How can I configure this on the ER 605?


Why all this? The traffic is currently split, as
both have approx. 100 Mbit. When the weather is bad, the Star Link
can drop to 20-30 Mbit. Then everything slows down in total. I want to avoid that.
I would like to avoid.

 

Thanks

Hi,

Have you checked the FAQ about load balancing?

 

https://www.tp-link.com/pl/support/faq/4058/

 

It's not 100% your particular case but (I think) it's the closest as it can be. I guess your ratio could be set like 5:1 or something like that.

 

Cheers.

Hello,
I don't know how this should help me. Well, Star link fluctuates between 20 and 150 Mbit for me. What would a fixed ratio do for me, because Telekom is fixed at 100 Mbit, Star link is not.

Thank you
Haase

Hmmm. I'm afraid the functionality you are looking for is called Link Aggregation (LAG) which would allow you to utilize both links bandwidth at the same time (1st like is 100% occupied, rest of the traffic goes to 2nd link). 

That functionality is not supported by Er605 as far as I know. 

 

There's only simple failover function (once 1st link is down, the router switch to link 2, and back when 1st is online again). 

 

The only thing you could do to utilize both links at the same time is to create policy routing rules. Which will redirecting some of the traffic to 2nd link... Always... Which means, even if the speed of that 2nd link is low. 

 

Here's some comment about simple load balancing from TP-Link:

"How does Load Balance feature works?

 

Actually, Load Balance selects which WAN port is session-based. If you use FTP to download a video, PC will establish only one session with end-point. When you have a lot of sessions with end-points, Load Balance router can assign these connections to different WAN ports according to router’s policy, in this way all the bandwidths of WAN links are in good use to speed up the whole traffic. That is why Load Balance router can aggregate several WAN links together.

 

Speedtest® speed test for each test is one single TCP session, so a Speedtest® test could only make use of one single WAN port (one ISP). So the above test mechanism is essentially wrong."

Hello,

Thank you for your feedback. Let me ask you a question. Can I also
set a ratio WAN1 (Telekom) and WAN2 (Star link). E.G. WAN1:WAN2 =5:4.
This means that the data traffic is divided according to this ratio.

 

Other Question: Does TP link offer a swich with LAG?


Thank you

Switch supports LAG if it is manageable. Unmanaged switch, as its name, nope.

 

Settings the ratio does not guarantee or prioritize the traffic. Load balancing is still based on the algorithm and sessions.
