Title: Ftp connection unable through the powerline
Post by: umby75 on February 13, 2019, 05:59:26 AM
Hi, I'm using a TpLink W8980 router and a TpLink powerline in my network.
I need to transfer very large files over my Wifi Lan to and from my phone/pc and I've noticed that when you are near the router the connection is established and the files is transferred but I'm with my devices near my powerline that it has  the same Ap's router name I can't connect the other device.
Why do you think is this happen?

Are you sure your powerlines are in sync across the power circuits?

Yes because I'm navigating through the powerline as I'm sending you this message...

Why did you ask that?

So everything else works, except for FTP?

Or do you mean that an active FTP transfer is interrupted when you move towards that powerline?

Yes. The problem occurs when I'm with my devices near my wifi powerline adapter and they're connected to it.
The Ftp connection doesn't work but if I take the devices in the router's room the connection is established as 7Mb/s speed.

Do you have the model of the router and the model of the powerline?

The only powerline I know is ethernet through the mains power circuit. If you have a powerline with a configurable wifi AP inside, then you can keep the SSID / Wifi name the same as on the wifi router, but you must choose a different channel. If it's 2.4GHz then use either channels: 1 or 6 or 11.

If you keep the channel the same then your devices will clash and you will not have a good wifi connection, if at all.

Otherwise more info might be helpful :)

I encounter the issue only for Ftp transferring and I don't think that could be a selected channel used..
My powerline kit is:
TP-Link TL-WPA4220 Kit Powerline WiFi, AV600 Mbps on Powerline, 300 Mbps on WiFi 2.4 GHz, 2 Ethernet ports, Plug and Play, WiFi Clone, HomePlug AV

The router is:
TP-Link W8980

Looks like it's doing a wireless repeater function but I am not 100% sure. Wireless (b/g/n) is half duplex. Adding a repeater into the mix makes it kind of like 1/4 duplex  :eek:
I'm guessing either that there is some loss and a timeout or the FTP signaling is dropping.

Have you tried different FTP mode to see if you have a different experience? ref: http://slacksite.com/other/ftp.html

At this point I'd be setting up a wireshark packet capture to see what is going on.

Thanks my friend...

I noticed that if I use two devices connected to the different access points (one to powerline and another to the router) the connection is established but I noticed inconstant speed with significant drops of speed and that maybe depends on my home's electric system where I connected the powerline kit..

I think it explains that the configuration is fine and the ports are well configured.
What you linked to me about Slacksite.com is quite technical but I don't think is a Ftp mode issue..and what I described at beginning of this post is meaningful..

Yeah, repeaters are rough things to work with. That is why I junked mine and went with a local mesh system. Much better coverage and signal strength.

Ok. Thanks. But how does it work a mesh system?
Excuse me for the OT post..

A mesh system is more like what commercial wireless is, with access points providing overlapping coverage with the same wireless network.

A repeater picks up the main signal and then broadcasts another network that connects into that main signal, so it's not the same strength.

tho' there is that line of sight issue that keeps me from running mesh.
