So, I have recently purchased a second gigabit router that will broadcast on another Wi-Fi network in order to improve connection speeds across the house, as well as giving me an ethernet connection in my room.
The way it's all hooked up is the following.
- Main router
- Secondary router.
1 is connected to 2, and 2 is then connected to 3.
The connections between 1 and 2, as well as 2 and 3, are ethernet cables (EN 50288-3-1).
Now, a quick Google search on this cable, EN 50288-3-1, reveales that it is supposedly capped at 100 MHz, which if I have understood correctly, should give me maximum speed of 100 Mbps.
The problem is that the connection from 1 to 2 is 1 Gbps, however, the connection from 2 to 3 is only 100 Mbps, but they use the same cable type.
Also, I have another cable that says it's CAT 5e, and states it is also EN 50288-3-1, leading me to madness.
Now, I have done a lot of tests to see if my secondary router was to blame or if it was the cable from 2 to 3 itself. I have tried connecting the cable from to 2 to 3 to my computer, getting only 100 Mbps. I have also tried using the cable from 1 to 2 to connect between my switch and secondary router, getting a 1 Gbps connection. I have tried connecting my router to the CAT 5e cable that says it's a EN 50288-3-1 as well, getting a 1Gbps connection too.
This all leads me to believe that, if the same cable type gives 1 Gbps from 1 to 2, but only 100 Mbps from to 2 to 3, and neither 2 nor 3 are to blame, it has to be the cable from 2 to 3.
Now, this is very bad, as the cable from 2 to 3 is not easily replaceable, it goes through tubes in walls and all that crap, and is probably 10 meters long.
I just wanted to check whether my reasoning that the cable is at fault is correct, because I'm going crazy at the moment.
For future reference,
- 2, the switch, is a NETGEAR GS105.
- 3, the secondary router is a TPLINK AC 1750
- Both cables from 1 to 2, and 2 to 3 are EN 50288-3-1, which, even though their specification says shouldn't happen, appear to be able to deliver 1 Gbps, and from 1 to 2, it does so.
If needed, I'll draw a simplified diagram of the situation and link it up so that the problem can be discussed in an easier manner.
