After these steps, see if the “Browser Only Slow” symptom decreases or disappears. If there are no changes, the possibility of extensions will also be checked in the next step.

You can remove outdated or incorrect DNS cache.
You can check for current DNS server failures or response delays.
Programs that intercept DNS requests can block certain sites.
We've put together a list of things we frequently check regarding this issue.
If the symptoms do not match exactly, please check the issue below.
If “DNS errors” occur repeatedly, it is better to narrow the scope to DNS server response issues and DNS cache rather than changing several settings at once. First, determine whether the Internet itself was disconnected or just name resolution failed, and then check your DNS settings.
If the current symptom is closer to “only a specific site does not open,” first check the DNS/browser cache, site, or ISP path. First, determine whether the Internet itself was disconnected or just name resolution failed, and then check your DNS settings.
When troubleshooting particularly slow Wi-Fi speeds, it is important to rule out the causes one at a time. Based on the “Slow Wi-Fi” symptom, check for weak signal, interference, or 2.4GHz congestion before proceeding to the next step. Check the wireless adapter status, saved profiles, router/signal quality, and driver in order.
If “No internet after update” repeats, it is better to narrow the scope to updated network drivers and changes to TCP/IP settings rather than changing several settings at once. Compare with other devices and wired connections to narrow down where the problem occurs: PC, router, or ISP.
