My setup with Skinny is Huawei HG659 and an ethernet connection from it to a Synology RT1900ac to supply wifi at the far end of the house.

 

Up till now, wifi speed from both was in the region of 50/20.

 

With fibre connected, the Huawei is doing 230/100 but the Synology is only doing 90/90, these are both wifi speeds.

 

Should the Synology be able to do better than this and if so, any suggestions on what I need to do to improve it?

 

Thanks.

Being Wifi could be a number of things. But first I'd check is that your ethernet connection between the two units isnt stuck at 100Mbps.

Check that the Synology has a 1Gbs ethernet connection....

 

90/90 sound suspiciously like the backhaul may have synced at 100mbs

I ran a speed test on my computer which is connected to the Synology by ethernet and got 93/94.

Looks like there is a 100mbs connection somewhere .....

Replace the Ethernet cable, between the Huawei and Synology.

 

(before you do - photograph the ETH port lights (colour) )

 

Sounds like they are connected at 100mb - likely cabling issue.

Had a look at the port light which is orange, not green :-( so looks like I need to run new cabling. Thanks for the help.

Buy a cable tester.

Have you tried reseating the cables every where first? Costs nothing other than 2 minutes of time. Might yield nothing. But also you might find it all renegotiates at 1Gbps. If that doesnt work then start with looking at replacing cables.

Some ethernet cables were built or punched down with only four wires/two pairs (usually orange and green). This limits speeds to 100Mb/s. This is generally only patch leads not fixed cabling, although sometimes people split a four-pair cable into two separate 100Mb/s 2-pair links. 

 

 

 

You might find it's only a patch lead that's built cheap, or it might be termination issues breaking one pair.

I have reseated the cables to no effect. Ill get a cable tester to try to track it down but there is one thing puzzling me. In the Huawei HG659 settings, under Lan Interface, it has this............

 

LAN1:

 

Connected Full 100Mbps

 

 

LAN2:

 

Connected Full 100Mbps

 

 

LAN3:

 

Disconnected

 

 

LAN4:

 

Disconnected

 

 

 

Your computer connects to a LAN interface to access the Internet. You can adjust the interface parameters according to LAN IP address allocation.
Why does it say "Full 100Mbps" when the specs say this " It has four Ethernet ports (RJ45) that support 10/100/1000 Mbps, including one Gigabit Ethernet port"

Did you check the cable, what’s the printed speed / “CAT” on the cable itself?

 

and is it a straight connection or are you running via a switch and if via a switch, what’s the rated speed of said switch?

Is the Synology connected via Ethernet? 

 

If yes, then you should change the cable and try again. 

 

Also check that neither the Synology nor the Huawei have the "Green" option, which limits speeds. On your Synology it will be "Energy Saving" under Internet.

 

Also, make sure the Synology is connected at 1 Gbps:

The Synology is set as a wireless AP and is connected from the Huawei to Port 1. Is that the correct one to use?

I'm pretty sure all ports on both routers are gigabit-capable. They could be limited in software to 100Mb/s on either end. Note that 'full' refers to full duplex, not full speed.

 

 

 

Look closely at the plugs on each end of the cable. You'll be able to see if there's four or eight wires present.
