The router is generally the issue, as it controls internet access, while the ISP handles the connection to the network.

This problem arose from my own mistakes. Thank you for checking. It’s left here for anyone searching later. I’m seeking assistance in pinpointing the issue and describing what steps I’ve taken, along with my equipment.
Issue: Internet connection fluctuates—some sites work while others don’t. I can’t load Microsoft updates or origin content, nor can I access Linksys or Pandora. Cnet, Google, YouTube are functional. Speed dropped noticeably over the past few days, affecting both wired and wireless connections.
Hardware: Frontier Fios ONT connected to Ethernet, ISP connection directly into router (no modem). Router is a Linksys WR 1900AC, about 2-3 years old.
Troubleshooting attempts:
- Assumed the problem was only on my desktop; performed a fresh Windows 10 install without success.
- Configured router to use Google’s DNS (8.8.8.8) – improved some sites.
- Confirmed the issue is network-wide across all devices.
- Used phone as a Wi-Fi hotspot; everything worked fine.
Actions taken:
- Ran `netsh winsock reset`, `netsh int ipv4 reset`, and `netsh int ipv6 reset` – no effect.
- Cleared DNS cache.
- Performed factory reset on router.
- Connected Ethernet directly from ONT to computer (same results; possible IP-related cause).
Current uncertainty: I’m unsure whether the problem lies with my ISP or my router. I’m considering contacting my ISP due to these findings.
I'm accelerating quickly now, actually only about 70% of the sites are loading.
Check if your ISP offers router configuration options. 1. Open the Windows search bar and type 'cmd'. 2. Execute the command 'ipconfig/all'. 3. Locate your IP address (typically on the second line of Default Gateway). 4. Enter it into a browser and look for any login prompts. 5. If asked for admin credentials, they should be printed on your router’s label.
I think I'm making a big mistake, sorry if I've been wasting your time. I called my ISP several times today but kept getting long hold times. When I tried to return, I got through. Discover moved my card to a different tier a few months back, and it seems my bill was set up for automatic payment, which they said was overdue at the same time my new card arrived. I didn't realize there was anything on the card that was automatically billed. Anyway, I'm surprised I could still reach some sites using Google DNS even though their service is limited.
