EX6410 WiFi extender Ethernet speed seems low

Question

My model is actually an EX6410 but that wasn't in the list!

I have a wired gigabit network downstairs in the house together with a Sky Q wireless set also connected via the Sky hub router. I bought the extender to allow me to connect a desktop pc to the network from upstairs.

I have updated the firmware to the latest.

I do not need the WiFi functionality, just access to the network from upstairs.

I have connected the extender to the network using the fast Lane method, on the 5 GHz band. The extender reports a connection speed of 975Mbps, which is pretty good. I have a Cat6 cable from the extender to the PC, and all the port lights show green (gigabit) connections.

My problem is that the speed of transfer over this setup seems low. I achieve 100Mbps on large file transfers (9-10 MBps). I know there are overheads in the extender, but this is only one tenth of the connection speed.

Is that normal?

Hello everyoneThere has been a development, and I apologise for wasting people's time.&nbsp;I had assumed that they Sky WiFi was working properly. That was a false assumption.&nbsp;I took the EX6410 downstairs and connected it to my network as an Access Point. Immediately I was able to transfer files at about 650Mbps on the laptop, which had a link speed to the extender of 866Mbps.Connecting to the Sky router wirelessly from the laptop, sitting right next to the router, the transfer speed was once again only 100Mbps. So the problem is that the Sky hub, which is an 802.11ac hub, is only transferring at 100Mbps. When the extender was connecting upstairs it was being stifled by the rate at which Sky was transmitting, not the link speed or any issue with the extender.&nbsp;I must now look further.&nbsp;thanks for all your help and suggestions

there is network overhead but we usually expect aournd 55-65% of link speed. Especially if you're hardwired. If your using it as an extender, you also take a 50% speed hit but you're hardwired in, so you shouldn't take that hit .

have you checked the cable to ensure its cat 5e or > and that its a good cable?

Is the computer gigabit?

Hello there.Thanks for your reply.&nbsp;This is puzzling me a lot!The extender is hard wired to a desktop PC with a Cat6 cable. The cable is known to be good, but I have swapped it for another one with the same results.According to the PC, the network connection is 1000Mbps, and the led on the ethernet port is glowing green. The port light on the extender is also glowing green for Gigabit.The Nighthawk app on the iPad shows that the link to the PC is also 1000Mbps.So everything checks out at that end.&nbsp;The extender has been configured with a staic IP address - The whole of the network infrastructure has static IPs, and the whole range has been excluded from the DHCP server's allocation, so no chance of overlap.&nbsp;When I access the extender's IP address from a browser, I see that the link from the extender to the main router is at least 975Mbps. At the moment it is over 1500Mbps, but the file transfer is stubbornly sitting at 8-10MBps, so 80-100Mbps.&nbsp;The green LED on the extender for connection to the router is, of course, green.I updated the firmware to V1.0.0.134 and subsequently did a factory reset.&nbsp;Any ideas?&nbsp;

That's a pretty solid link speed.&nbsp;What wireless 5ghz speeds are you getting from the extender?

BobbyJames · Answer

I have the extender set to fast lane, which means that the link to the router uses one of the bands exclusively and the extender to devices uses the other band. Because I want maximum speed for the Ethernet connection I have configured the extender to use the 5GHz channel back to the router, so any devices can only use the 2.4 ghz band at their end.&nbsp;I tried using the standard settings which use both bands to both ends of the chain but that was just the same.&nbsp;
