Trying to understand what's happening and not getting very far so returning to see if someone will explain the ins and outs to me. A while ago I was told to stop using my WIFI repeater. It does seem to have reduced the frequency of problems - although not totally vanquished them. So I looked at the extender in more depth and tried it as an access point. Had a problem today so I'm still pondering my options. I can revert to 2.4G WIFI at the other end of the house - but obviously prefer to stay with 5G.
I figure that the advice to stop using the extender was based on something - but there were not other details. So am hoping someone can flesh it out for me.

Extenders use mac address spoofing to remain compatible with all accesspoints, as the proper way of WDS bridging is not part of the standard so is hit and miss depending on what you connect to.

 

As things transition between the extender and the main accesspoint, the mac address the rest of the network sees them as will change between the spoofed one that is the extenders, and its real one. This means that the arp table of the router and other devices will be wrong, and that is something that a lot of devices fail on. Also intrusion detection software on things will see the mac address change and report that as someone trying to screw with the network.

 

They break broadcast stuff, so have software fixes in place to allow upnp and bonjhour and other broadcast based things to work over them. Mostly work. Sometimes not work.

 

They are just a nasty hack.

 

With it as an accesspoint cabled back, then all devices keep their real mac address as they move between the added AP and the AP built into the router, so the IP stacks on the other devices do not need to time out or have changes happen, but you are still reliant on the bridging between networks seeing the device move, and that is something that I have found the netcomm NF4V is hopeless at, so if you are using one of those or the AC version it may explain problems.

Thanks for that (I think - the details are a bit over my head ). Our router's a Belkin - although I did get a Netcomm NF8AC when things were really bad and I couldn't eliminate the Belkin as a cause. So it's just a test machine - already had the extender - but neither seems particularly more problematic than the other. The extender / access point is an Edimax.
So i guess I'll just keep fiddling - looking at IP stacks and bridging.
Thanks again for your time.

Wow. Haven't digested it all - but what I've taken in is really helpful. Thanks

Having had time to think about it, if I were starting from scratch, it seems the best solution in our little house would be to have the access point in the centre.
That is difficult. Apart from moving the line in, we have a UPS, router, switch, VOIP box and two phones all around the access point, plus cabling under the house to the far end. All of this takes up space and requires connecting to each other.
I'm wondering if there would be a greater chance of an extender working if it was the same as the router? Either the same make, or the same model but configured as an access point.
Would it still be hit and miss. It seems like a good idea made very tricky to work for the 90% of us who don't know these things.
Thanks

Instead of a repeater, are you unable to run cable to a better located access point?

Any (wired) Wireless Access Point will outperform any wireless repeater.

I have a wired access point - but still have problems. Just found that the access point should have a different SSID. Interesting it seems to have dropped the power of the signal (which just means using the main router from this end of the house) - but am waiting to see what else happens.
Thanks

Homeplugs mean you can put your access point almost anywhere in a house with a single phase power supply.

+2 (only because I use two homeplugs)

 

My router / modem is also on one side of the house. Pointless activating Wi-Fi there. Using Ethernet over Power I've managed to move my wireless access point more centrally. Now I have once access point upstairs and the other downstairs. Both use the same SSID. No more timeouts, smooth music / video streaming.
