Computer loses internet every few days. Must reboot to restore

I have a PC that I built a little over a year ago. A couple of months ago it started losing internet connection every couple of days. The computer SAYS it is connected to the network and internet is available but web pages can't be reached and I cannot connect to my ftp server or any internet required apps. The only way to fix the problem seems to be to reboot the PC. Once rebooted everything is fine for a day or two.

I believe the wireless router is fine, as I have no issue with any other connected device (iPhone, tablet or other computers). I was certain that my USB WiFi receiver was going bad so I eliminated it and directly connected to my router via Ethernet cable. The problem still persists.

Every driver is up to date and Windows has been updated.

Has anyone experienced anything like this?

We frequently find that the connection to the ISP is still functional, but the DNS has problems.

There are TWO dns addresses that everyone (usually) finds helpful
  1. 8.8.8.8
  2. 8.8.4.4
You can make that change in the Router (to help all connected devices) or on the PC in the network adaptor itself.

Two days later and I lost internet again. Sadly the dns addresses did not help.
 
OKAY, let's probe deeper.

Where are you geographically, who's your ISP and let's test your access:

  1. get a command prompt window
  2. enter pathping 8.8.8.8 >googlePath.txt
(2) typically will take ~3 minutes so be patient.

When it completes, in that same window enter
  • notepad (wordpad if you're in win/10) googlePath.txt
  • Copy the content and PASTE it with your reply

Looks good - - they're all 0/100 which is perfect.

Didn't say your location & ISP :- ???

Is the modem Cable or DSL?

Hmm, maybe. Windows/10 frequently LIES as it uses it's own list of drivers instead of looking the the NIC (or WiFi) website for the information, so don't rely upon Windows Update to be accurate.

Your PC is at 192.168.1.136 and your router 192.168.1.1

What is at 10.50.0.1 ?? that's a second router or AP and it's yours

I have a second router but this computer isn't connected to it. It's in another part of my house for my mining rig.

But your traffic goes thru it anyway - - check it out

see post#14 proof above
 
I'm not sure that makes any sense. The second router comes off the router my computer is hard wired to.

It goes like this:

Cable modem > Linksys router
ethernet wire from linksys router to:

1 - problematic PC
2- netgear router

The only thing connected to the netgear router is my mining rig
 
I will disconnect it altogether. I could just wire my mining rig directly to the Linksys router. I just use a second router to wirelessly connect my tablet to occasionally when on the other side of the house where my main router signal isn't so great.

The packet trace doesn't lie. Are you sure the PC is using the NIC and not the WiFI?
 
Don't know what you mean by NIC but it can't be using wifi, as I removed the wifi receiver from the PC.
 
What the actual flying frick? I just downloaded the firmware for my router and got this message. I redownloaded and tried again and it's still not working.

Sorry for multiple responses between your posts but I'm trying a few things. I completely disconnected the second router and ran another pathping. The following are the results. Are you still seeing anything weird?

A NIC is the Ethernet Network Interface card - - uses a cable and RJ45 connector.

Under the Device Manager

mine shows up as the Realtek PCIe; my WiFi device is the Dell Wireless 2 lines up

The Driver is 7.105.123.2017

I don't understand why 10.50.0.1 is still in the path to your ISP at 207.44.112.157

NOTHING from your PC gets to the ISP without going thru 10.50.0.1
