Here are a few prerequisites. I am running Linux 4.4.0-21-generic on Linux Mint 18 Sarah x64. Everytime my internet is enabled it causes the internet to lag the entire computer until a reboot. This happens with every linux distro installed. Arch, Ubuntu, Mint. All the same. This only happens when turning on the PC after being shutdown. BTW I dual boot Windows 10 and Linux. This also happens when plugged in via ethernet. Again, tested on a fresh install from all three Distros. Again, the internet doesn't slow, just the entire PC.

Turns on PC after being shutdown.
Loads Linux
Horrible Lag
Reboot
Lag is Gone, internet is fine.

I am running a Toshiba Laptop with AMD A6-4400M APU with Radeon HD Graphics 7000.

Update: I reformatted and installed via EUFI instead of legacy and performance is slightly better. After some googling I think it may be an IO problem. I look at IOtop and I'm getting 0 read and write with nothing using io. I'm thoroughly stumped. It only happens when dual booting windows. Without windows it works like a star.

Here is my top info

  • @roaima I use both Ethernet and wireless and it has the same effect and when I reboot it brings into grub where I select my Linux installation. – Dalton Smith Dec 4 '16 at 19:11
  • @roaima Added top on question. – Dalton Smith Dec 4 '16 at 23:00
  • Your system was running slow at the time you executed that top command? There's nothing obviously wrong there. In hindsight I think that a slightly different command would have provided more detail - top -b -n1 -o %CPU | head -20 - so if you fancy replacing your first top output with the result from this one that might be beneficial. – roaima Dec 4 '16 at 23:41

    @roaima Yes. My system was slow at the time of running the command. The top results will be replaced in about 8 minutes. – Dalton Smith Dec 4 '16 at 23:42
  • @roaima Replaced. Also might be useful to note that this effects response speed too. If I type a command using the Ctrl Alt F2 mode it takes slightly longer to respond than usual. – Dalton Smith Dec 4 '16 at 23:46

I have seen similar with a misconfigured iptables, but I recommend booting a live usb, or clean install, then configure untill you fined the problem causing step... maybe your kernel is not reserving enough space for itself...dmesg output might be informative.

  • How would I configure it, and I have booted into a live CD and it runs with less lag then when I haven rebooted. How would I fix this without deleting my windows partition as I have important data on it. – Dalton Smith Dec 5 '16 at 0:03
  • Here is my dmesg output. I used pastebin because it said the output was too long. pastebin.com/NjcAPfQm – Dalton Smith Dec 5 '16 at 0:20
  • So I wiped my hard-drive and installed Linux mint first (previously I installed Windows first) and it ran flawlessly. Then I installed Windows 10 alongside it and the same problem repeats. What the heck? – Dalton Smith Dec 15 '16 at 3:31
