This is a really strange one... so just moved into a new property and had to settle for a basic ADSL connection, Vodafone recently provided the connection to my property together with their standard wifi-hub... upon initial inspection simply running of the wifi-hub everything seemed ok, however now that I've put my pfsense (running version 2.6.0) behind the wifi-hub I'm seeing a lot of packet loss.
So the setup is exactly the same as it was in my previous property (where i had no issues). I basically have the pfsense WAN interface connected to one of the Vodafone wifi-hub ethernet ports and wifi-hub sits in the same network range as the pfsense WAN interface IP - Vodafone wifi-hub is .1 and the pfsense WAN interface IP is .254. I've placed the .254 address in the "DMZ" and I disabled all functions on the Vodafone wifi-hub, turning it essentially into a ADSL modem. But still have the annoying double NAT config!
Doing a continues ping (towards 1.1.1.1) from my desktop, connecting to the internet via my AP (which connects into a switch, which connects into pfsense) - I'm getting 50% plus packet loss.
The second hop below is the Vodafone wifi-hub, locally going from pfsense to wifi-hub it seems to be registering 65% loss!
Thinking this might be a wifi issue, I run a cable from my switch to my desktop - same result!
Thinking it might be a bad cable between the pfsense WAN interface and Vodafone router, I swapped cables multiple times - same result! I've tried the different ethernet ports on the Vodafone router always the same result - packet loss! Even played with the MTU and negotiation settings on the pfsense WAN interface - no luck!
Thinking this is pfsense related, I've done the same continues ping test connecting my desktop directly over the Vodafone wifi-hub, over both wifi and cabled connections registering 5-10% loss - which I guess is acceptable.
Although at some point yesterday I was registering, 25% loss connecting directly over the Vodafone wifi-hub - which led me to think there was something wrong with the line or the router - Vodafone engineer on the way to check line and router, who I doubt will find anything wrong.
Currently running quality monitor via thinkbroadband.com to make sure the issue is definitely not related with the connection itself.
Now despite all of this packet loss I'm registering, when connecting to internet via my pfsense, don't seem to be having any connectivity issues. No drops or buffering during streaming, no drops over VoIP, VPN connectivity seems solid, So I'm really confused???
My next move I think is to order a simple ADSL modem (Draytek Vigor 130) and remove the Vodafone wifi-hub out of the equation, got the login details from Vodafone, but looking for alternative suggestions before I go ahead with that plan and spend the money.
Yesterday I found out that I have no test socket. Hopefully the engineer who will attend Friday can resolve that at least, then we will see.
And I've disconnected everything from the Vodafone wifi-hub and run the continues ping test directly -
Over wifi -
Over cable -
Still registering packet loss.
Hmm, I had never seen the program you are using so I though I'd try it, and I got this:
Now I know I'm not actually getting packet loss, so I think that program is suspect. That would account for you seeing no actual problems when using the system.
Try just running a continuous ping from a command prompt and see if you are actually getting any. (ping 1.1.1.1 -t)
WinMTR is an application that combines the functionality of the traceroute and ping in a single network diagnostic tool.
If I run ping from cmd in parallel with the tool, I can see when it registers loss I also see ping drop in cmd. So nothing wrong with program.
