If some sites do not open on PC, but others sit and the internet work, what to do

If the internet does not work properly, the problems can be caused by both the internet operator and the internal network configuration. We can notice these problems and notice that Downloads never end and remain quietThat The connection goes and goesThat the streaming service jumps on the most beautiful or presents itself with a considerably lower quality than the beginning or that the direct zoom jumps on the most beautiful without giving any notification.

In this guide we will investigate the possible causes and the most effective solutions to solve the problem as the internet works, but some sites do not open or are very slow to load.

1) Check whether the problem only concerns a site or more sites

First check whether the problem only influences one website or more sites:

• If only one site is not openedIt can be a temporary problem of the server. Try to visit Downforeyareorjustme To check whether the site is actually offline.
• If multiple sites don’t workThe problem can be related to your PC or connection.

2) Start up the router and the PC again

Sometimes a simple restart can solve connection problems:

1. Switch off the router, wait 30 seconds and turn it back.
2. Restart the PC to update the network connection.

3) Try with another browser

If a site is not opened on Chrome, try Firefox, Edge or Opera. If it works, the problem can be an extension or a corrupt cache in the main browser.

4) Remove the browser’s cache and cookies

The temporary data collected in the browser can cause loading problems:

Su Chrome:

• Grant Ctrl + Shift + Canc → Select “All Periods” → Check cookies and other details of the sites “and” Images and files in the cache “→ Click on” Delete data “.

Su Firefox:

• Go up Impostazioni → Privacy e sicurezza → Cookie e dati dei siti → Cancella dati.

5) Check the Firewall and Antivirus settings

Sometimes firewall and antivirus block access to certain sites:

• Temporarily switch off the antivirus To check if that is the problem.
• Check the Windows Firewall:
  1. Type “firewall” in the start menu and open “Windows Defender Firewall”.
  2. Click on “Restoring standard settings” in the left column.

6) Change the PC DNS

DNS servers (which translate the web addresses into IP numbers) may not work correctly. Try to change the DNS:

1. Open Impostazioni di rete → Modifica opzioni scheda.
2. With the right button, click on your connection → Proprietà.
3. Select “Internet Protocol Version 4 (TCP/IPv4)” → Proprietà.
4. Choose “Use the following DNS server addresses and enter:
   • DNS Google: 8.8.8.8 one 8.8.4.4
   • Cloudflare: 1.1.1.1 one 1.0.0.1
5. Click OK And start the PC again.

If we are looking for a faster method to change the DNS on Windows, we can also trust the program DNS JumperAs can also be seen in the guide DNS -Server Edit in Windows Connection Settings.

7) Check the Windows “Hosts” file

Some malware change the file hosts To block certain sites. Here is how you can verify it:

1. Open the notes as administrator.
2. Go up File → Apri and navigate to C:\Windows\System32\drivers\etc\.
3. Select “All Files” and Open hosts.
4. If you see lines with suspicious addresses (eg. 127.0.0.1 google.com), remove and save.

8) Try an alternative connection (VPN or telephone hotspot)

If the problem persists, it may be that the sites that do not open at the local level are blocked in Italy.

• Use a VPN (as an opera, protonvpn or wind biberder) to bypass any provider blocks.
• Connect to the mobile phone network (via hotspot) to check whether the problem is related to your home network.

8) Switch off Proxy and VPN

If we have a webproxy or a VPN on the computer, they can be the cause of delays and blocks, because these systems are intervening between the computer connection and access to the sites and services we use.

To check whether no proxy is active on Windows, we open the app Institutions In the menu start we open the menu Rete and InternetWe open the lateral menu Proxy And we check whether the switches are not deactivated next to the items Detect automatic settings” Use configuration one USA Server Proxy.

If the problem is the VPN connections on the other hand. Menu Lateral VPN And we switch off or remove an present VPN. We can also search for VPN programs by opening the start menu and looking for VPN: if there is a theme program, we will see it immediately and we can deactivate, remove it.

9) Recovery the network settings

If nothing worked, restore the network configuration:

1. Open the command prompt as manager (Win + X → “Terminal admin”).
2. Type these assignments one by one and press Send after each:

   netsh winsock reset
   netsh int ip reset
   ipconfig /release
   ipconfig /renew
   ipconfig /flushdns

3. Restart the PC.

10) Change fashion settings

If we have tried all the methods seen so far on Windows, it is better to shift attention to the home modem, since in most cases he is responsible for the slowness of the connections.

First, let’s try to connect to the modem with another device, for example a smartphone, a tablet or another PC: if they go without problems, the problem is still on the computer, while if we also notice delays or blocks, the problem is definitely the modem. There are various methods to restore the functioning of a modem, but the most famous are undoubtedly:

• Use the 5 GHz: If our modem is a double tire, make sure you use the network connection WiFi on 5 GHz frequencyCertainly freer and less hidden.
• Change the WiFi channel: If we still use a lot of 2.4 GHz connections, we have access to the modem and Let’s change the transmission channelTo prevent interference.
• Change DNs worldwide: By changing the DNS directly in the modem, we can prevent missing connections with web services on all connected devices, without applying the suggestions above in any device.
• Restart the modem: With this system we will solve the temporary problems because of the internal cache of the modem or to errors because of the Tempon of high use (it is in fact a good habit to restart the modem at least once a month).
• Restore the modem: It can be a wise choice to restore the modem to the first settings, but only if we have a modem from the operator or have a backup of the fashion settings.
• Change modem: If the modem is too old, it can be a good idea to replace it with a new one, as to see in New generation of modem guide to buy.

Conclusions

If some sites do not open, but the connection works, the problem can depend on multiple factors: browser cache, DNS settings, firewalls or even malware. According to these steps you must be able to solve the problem without having to call a technician.
