Anonymous users2024-02-06My used 4741 is this silvery-white one.

Anonymous users2024-01-311) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.
2) If it's a problem with the router, such as teasing the fruit that can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. In there is a factory reset settings, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set up at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).
If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.
3) If you turn off the wireless switch, turn it on, if the mountain Luzi is connected to the wireless with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem 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.

Aries.
The overall image of Aries is like a careless sheep that only knows how to rush forward, so it often ignores details. However, it is full of energy, with an invisible force that can act anytime and anywhere, with its eyes on the target, with the momentum of a personal charging line, to pursue what it wants in a fairly short period of time, without taking into account the changes in the surrounding environment, and does not need to be touted by others. So, if Aries behaves well, they can break new ground; If it's not good, it will leave a lot of garbage behind, and it often needs someone else to clean it up. >>>More
