Samsung Tab A slow internet browsing



  • NEWBIE ALERT!

    Installed Pfsense 2.4 recently in the house and love it!

    Things are fantastic, I really feel that the whole network and internet response is much improved.

    One snag. Of the hundred devices I have attached to the router, both wired and wireless, ONE lone device, my Samsung Tab A is deadly slow on the internet. I don't get it!!! When I run SpeedTest it takes at least 60seconds to find a server, but after that it registers speeds in the the 100's of Mbps.

    Similarly it takes forever to load a page from the internet.

    I know this is a router issue, b/c when I connect the Tab to my phone hotspot, all speeds go back to normal.

    I have a TP-Link Deco AP attached to the router that provides the wireless.

    Again, every other device has speedy internet responsiveness except this ONE device. What the ….?



  • Potential DNS issue or IPv6 comes to mind. May want to do some packet captures.



  • Why do you assume IPv6?  I've been using it for 8 years without problem.  Also, if it was an IPv6 issue, it would affect everything.  Android devices have been working with IPv6 here, ever since I got a Nexus 1, several years ago.



  • Hi there. Hopefully I mentioned that I'm a noob!!!

    I used the pfsense diagnostics/packet capture and put the ip address of my Tab in the "host address field" (192.168.1.147). I started the capture, then loaded www.CNN.com into the Firefox browser on the Tab. After CNN (finally!) loaded, I stopped the capture. Below is the output. It's all Greek to me! Help!

  • Did I do it right? Can anyone help me?



  • @lyle817:

    Did I do it right? Can anyone help me?

    Well, you captured a lot of data, but it doesn't tell us much.  The pfSense Packet Capture doesn't show a lot of detail  It's better to download the capture and display it in Wireshark.  But even that wouldn't likely show your problem



  • Hi, there. Thanks for the advice. I downloaded the capture into WS. Very colorful, lots of red (bad?). Not sure how I would display the results here, but you said that it won't likely show my problem, so I guess I'm back to square one.

    Every other device works fine, even my Roku. This is the only android device in the house, maybe pfsense is incompatible with android? That would see bizarre to me.

    Hope someone can offer further advice!



  • People often display screen captures here.  Also, you can attach a file to posts, if needed.  Red in itself is not an issue.  Wireshark uses a variety of colours to denote various things.  What you'd be looking for are things like repeats, lost packets, ICMP error messages, etc.



  • OK, I attached the capture data here. I hope someone is willing to have a quick look and give me some advice. Unfortunately, it was all over my head.

  • The red in that capture is probably the firefox wifi tickler, nothing to worry about. The black however, are retransmits, something to look into. You might want to do another packet capture of all traffic and see if you have lots of broadcasts. Just a start.



  • OK, here is a packet capture of around 5mins or so with all traffic. Hope this helps!

    Sound like you don't think this is an android incompatibility issue?

    What would it be incompatible with?  IP is IP and Android is build on Linux.  I have a couple of Android devices and Linux computers and no problems with pfSense on either.  However, the retransmissions indicate a problem somewhere.  Is it with just one site?  Or several?



  • This is a single site (home network).

    Many thanks for your help!



  • @lyle817:

    This is a single site (home network).

    Many thanks for your help!

    When you use that Tab, are you trying to access different sites on the Internet?



  • Yes, that's right. Access to my local LAN assets seems to be fine, it's just the monster delays when accessing different sites on the internet. Also using speed tests like Speedtest and Fast.com



  • @lyle817:

    OK, here is a packet capture of around 5mins or so with all traffic. Hope this helps!

    Sound like you don't think this is an android incompatibility issue?

    Only 100 packets captured in this one, 0.47s, (check your settings), and looks like you did it on WAN? Lots of broadcast noise there.
    Do another capture with 'count' set to 0 and give it a few minutes. Try to access several sites with your tab during the capture.



  • Hi there. Sorry to say that when I went back to my Tab to perform another packet capture, everything was working fine. I gave it 24 hrs and things are still fine with speedy  internet browsing on the Tab. I've been living with the terrible performance for about three weeks and have not made any changes to pfsense or the network hardware. I hate unsolved mysteries!!

    Thank you all for your help and suggestions. Looks like I'm good for now and will report back if things fall back to the previous conditions.
