Hi, 

Recently I have purchased a set of TP Link powerline . I have successfully managed to sync and connect my powerline with superhub to get internet on attic. So internet set is :

1st Powerline is wired to superhub. 

2nd Powerline on Attic and is wired to my Wifi Extender (instead of wired connection to laptop)

The problem is I can connect to internet on attic over Wifi Extender but when I'm on ground floor I try and connect to superhub but after installing the Powerline , I cannot connect to superhub and all the devices that are connected via superhub gets disconnected. I have tried many different things but nothing works . Any chance someone can advise something?. I feel like it's might be the super Hub issue?.

If the Hub is in Modem Mode you need to use the IP Address 192.168.100.1.

In Modem Mode only 1 ethernet port is enabled.

If the Hub is in Router Mode you need to use the IP Address 192.168.0.1.

Try the connecting the laptop to the Hub by using the ethernet cable that goes to the Power Line Adaptor.

Hello, 

I have just checked and the modem mode is not enabled. I'm not what's the issue is. Any more help? 

[MikeRobbo]

Did you connect up as advised ?

Hello,

Yes, my laptop is getting around 90mbps when wired to superhub. So wondering, what's the likely the issue then?

OK.

Reconnect the Power Line Adaptor (PLA) next to the Hub.

then

Go to the furthest PLA and disconnect your WAP and connect the laptop using the ethernet cable and run another speed test.

What do you get ?

Hi, 

That works but why adding WiFi extender to Powerline causing devices to lose connection to superhub and cannot connect to superhub?. Any idea or work around?. My work Mac laptop doesn't have a ethernet port but my personal laptop does.

[MikeRobbo]

Start with the Mac not having an ethernet port. Adaptors are available from the regular online places and TBH always use ethernet in preference to Wi-Fi.

As for the dropping out of the Wi-Fi, it is difficult to visualise the LAN to make any kind of comment about it.

Sometimes a simple line drawing of how the network is set up can help enormously to figure things out.

Hello,

Just want to let you know that I have managed to fix the issue. I just changed the WIFI externder operation mode to from "Wifi extender" to "Access Point" and then wired the second Powerline to Wifi extender . Not it's working .🙂

So overall 

1st Powerline wired to superhub

2nd Powerline wired to Wifi extender (After changing the operation mode from "Wifi extender" to "Access Point". In my TP link App settings.

@Attitude-24 I'm guessing that in "WiFi Extender" mode the TP Link has it's own DHCP server and that would clash with the VM hub's DHCP server.  Having more than one DHCP server on the same subnet can cause issues, because devices don't know which server to ask for an IP address, and you get conflicts and network collision and all kinds of annoyances.
