2) If it's a router problem, if it worked before, it won't work for the time being. My own way is to disconnect the power of the router and plug it in. See you later. If yes, you can restore the factory settings and start using them from the new settings (this is sometimes caused by the slow or failed IP address search of the router under the premise of correct physical connection, not the router is broken).
If I can't solve it all the time, I suggest calling the customer service of the router. They have telephone online guidance. If I encounter problems that I can't solve, it is very useful to ask their advice. They will provide correct advice for your setup or operation.
3) If the wireless switch is off, just turn it on. If it is a software wireless connection, the software is not easy to use, and it is normal to have problems frequently. There is no better way to use a router. In addition, the network card driver is not suitable or not suitable, and there is something wrong with the network cable interface or network cable.
4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.
5) If the browser is not easy to use, it is recommended to test it with Google browser, which is very easy to use.
6) If you have any questions, please ask me.
The above is a network problem, which sometimes happens on your computer card.
1) The computer screen is stuck or what are you doing on the computer when you say this symptom? Can you tell me something? I will give you a more accurate answer according to what you said.
Please elaborate on your computer performance before the screen stuck or crashed, and your operation, which may be the cause of the screen stuck or crashed. Ask me if you have any questions (I will answer you again according to the information you provided).
Generally, the screen jam or crash is caused by your incorrect operation. Remember not to do anything that may cause a screen jam or crash. Don't operate the computer at full load, that is, when playing games, watching videos, downloading and watching web pages, it is most likely to restart, crash and blue screen when doing other operations, so don't operate other things when playing games, watching videos, downloading and watching web pages.
In terms of hardware, if the memory stick is small, add the memory stick. The temperature of CPU and other hardware is too high, and the hard disk is broken, all of which are caused by improper hardware.
2) If it is related to hardware, one is that your memory is low, the temperature of hardware such as CPU is high-definition, and there is something wrong with the hard disk. On the soft side, uninstall what was downloaded before the accident, download Win cleaning assistant to kill Trojans, restore the system or reinstall it, and don't run at full capacity if there is one.
Win78 can basically run 4G memory, XP is 2G memory, and it is best to double it. If you don't use this number, it is recommended to add more memory (this is a practical number, not a theoretical number).
