Certain website not loading

Hi there,

[Note that I am actually posting on behalf of a colleague because the issue she is describing above prevented her from posting herself]

Recently, certain browsers have been taking forever to load (or don't load at all) and I'm looking for help to resolve the issue. For example, YouTube, Instagram, Facebook, Dropbox, and Asana won't load but aren't blocked and can be accessed by my colleagues. However, I can load other websites and Google searches load quickly without any issues.

Also, apps work fine on my computer; it's only when I'm trying to load webpages that I experience this issue.

Here's what I've tried so far:

  • Updated IOS (I am on Windows 11 Pro, version 25H2)
  • Cleared the cache
  • Ran diagnostics
  • Reset my network
  • Used different web browsers (Chrome, Firefox, Edge) - they all have the same issue
  • Trying different wifi networks - the issue persists at home and at the office
  • I followed the instructions in this video: https://www.youtube.com/watch?v=eD0SNMNMV00
  • Toggled the graphics acceleration on and off

I am using a Dell Vostro 15 7510, and the BIOS date is 2021.

This issue appeared out of nowhere. I didn't do any recent updates or download any new apps/software prior to this issue.

Another bizarre thing is that the exact same issue has begun to affect another coworker's laptop, only a day or so after it started affecting mine.

Any advice on what else I should try?

    Hello SSISC co-EDs,

    Welcome to Microsoft Q&A forum.

    Based on your description, the issue in this case might be lying on the internet settings of the computer. Also, I'd say there might be a chance that this is malware doing, since the symptom has now spread.

    Before we proceed further, may I know if there are any error message when the affected page failed to load? Also, may I know if you have tried to change the network DNS to see if it helps?

    I'm waiting for your reply.

    Because multiple major sites fail in all browsers and on different Wi‑Fi networks, the most likely cause is a general network quality or Wi‑Fi issue rather than a specific browser problem.

    Try these steps in order:

    1. Improve Wi‑Fi/network quality
    • Move the laptop closer to the wireless access point and remove obstructions.
    • If possible, switch temporarily to a wired Ethernet connection and test those same sites.
    • If on Wi‑Fi, try a different access point (for example, a guest SSID) to see if behavior changes.
    • Check whether other computers on the same network are doing heavy downloads/streams; pause those and test again.
    • Ensure the router/modem firmware is up to date (check the router’s admin page or vendor documentation).
    • Inspect the cables between router and modem for damage or loose connections.
    1. Compare behavior on another device
    • On the same network, use a different PC or phone and try to open YouTube, Instagram, Facebook, Dropbox, and Asana.
      • If they are also slow or not loading, the issue is likely with the router/ISP; contact the ISP (for home) or IT support (for office).
      • If they work fine on other devices but not on the affected laptops, continue with the next steps.
    1. Run Windows Wi‑Fi troubleshooting
    • On Windows 11, run the Network and Internet troubleshooter in the Get Help app as described in the Wi‑Fi troubleshooting article. Let it complete diagnostics and apply any fixes it suggests.
    1. Address slow/unstable Wi‑Fi specifically
    • Check Wi‑Fi signal strength on the taskbar; if it’s low, prioritize improving signal (closer to AP, fewer walls, less interference).
    • Disable background apps that may consume bandwidth:
      • Open Task Manager (Ctrl+Shift+Esc) and end processes that are using high network bandwidth.
    • If the Wi‑Fi connection drops or fluctuates frequently:
      • Go to Control Panel → Hardware and Sound → Power Options → Change plan settings → Change advanced power settings.
      • Expand Wireless Adapter Settings → Power Saving Mode and set it to Maximum Performance.
      • On the router, change the wireless channel to reduce interference (see router manual).
    1. Test with another network entirely
    • Connect the laptop to a different physical network (for example, a friend’s home or a mobile hotspot) and test the same sites.
      • If everything works there, the problem is almost certainly with the original networks’ routing or ISP; contact the ISP or network admin.

    If, after these steps, only specific sites remain affected on these two laptops while other devices and networks are fine, escalate to the organization’s IT/network team or ISP with details (sites affected, time of day, and that multiple machines are impacted). They can check for routing, DNS, or filtering issues upstream.
