A few questions about the wireless SIM card, well, there is an additional !!

You're talking about a 3G Internet card, there is no roaming charge on the 3G network, so there will be no regional restrictions, you can use it anywhere, as long as there is a 3G signal.

For the market price, you can consult the three operators (China Mobile, China Telecom, and China Unicom).

You can try Telecom's wireless network experience card 55 hours 100 yuan No need to buy any external and internal equipment As long as there is wifi coverage in the area, you can access the Internet wirelessly The Internet speed is very good.

According to your needs, you can use the traffic one.

Mobile, Unicom, and telecom equipment are different, and the tariff cards are also different, so I can't list them all.

Packet traffic is divided into local traffic and domestic traffic, and there are no regional restrictions when packing. I didn't buy a wireless network card, but a wireless network card that can insert a 3G card, don't buy the wrong one.

You don't need any equipment, just buy a network card, you can use it, as long as your network card has an Internet fee, it's good to pay a monthly fee, I think the package time is not appropriate.

Buy a local one, you can give it to relatives and friends if you can't use it up, and the children here are over 16 years old.

Before using the service, you need to make the following preparations:

1) Install the client software on your PC.

2) Insert the UIM card into the network card and connect the network card to the PC (this operation is not required if the wireless broadband (1X) and wireless broadband (3G) networks are not connected).

3) Turn on the WLAN access device on the PC and set the wireless broadband (WLAN) access account in the client software (this operation is not required if you are not connected to wireless broadband (WLAN).

Detailed solution:

1. Open the device manager of your computer and look for the "modem" item.

2. If there is, click on the "+" sign on the side of the modem to see if there is an EVDO wireless network card of the corresponding brand. If the ZTE AC560 3G wireless SIM card driver is installed correctly, the modem with the name CT ZTE EV-DO modem will be displayed.

3 If the following three situations occur: 1. There is no modem 2, and there is no EVDO wireless network card of the corresponding brand under the modem3, although the EVDO wireless network card of the corresponding brand appears, but there is a yellow question mark on the left; It means that the driver of the 3G wireless network card is not installed well, or the driver is damaged, and the driver of the 3G wireless network card needs to be reinstalled.

3G data card (network card) driver installation method:

1. Start the China Telecom client installer, when installing, select "only install the network card driver" to complete the installation of the driver, in the process of installation, it is best to turn off the real-time monitoring software, such as anti-virus software, security guard, etc., if there is a security warning, please select the option to allow or always allow.

First of all, look at what brand of wireless network card you have! Down drive! Wi-Fi!

Is it customized, such as, telecom (generally the next universal wireless network card driver can), mobile, and Unicom. Go to the official website to take a look! If you can't do it, you can go to the business hall!

I'll help you install it for free!

I don't have a wireless card driver, try to see if I have a driver.

Problem description: I heard others say that if you have something, even the lift-up machine can also be connected to the Internet anywhere!

What is a wireless network card?

Can anyone tell me something about this! ~

Thank you! ~

Analysis: 1. The so-called wireless network is a wireless local area network (WLAN) composed of radio waves as a medium for information transmission, which is very similar to the use of wired networks, the biggest difference is the difference in the transmission medium, and the use of radio technology to replace network cables can be backed up with wired networks.

2. There are three common standards:

IEEE: Uses the 5GHz band, the transmission speed is 54Mbps, and it is not compatible.

IEEE: Frequency band, transmission speed 11Mbps

IEEE: Using frequency bands, the transmission speed is 54Mbps, which is backward compatible.

Currently, IEEE is the most commonly used, but IEEE has the power of next-generation standards.

3. A wireless network card alone cannot be connected to a wireless network, and a wireless AP must also be used, which is equivalent to a hub for a wired network. The wireless network can only be connected if the wireless AP can be covered by the appropriate settings.

Wireless Internet access relies on wireless network cards, of course, supporting wireless routing (wireless cat).

The wireless network card is equivalent to the receiver, and the wireless router (wireless modem) is equivalent to the transmitter. In fact, it is still necessary for the wired inter line to be connected to the wireless modem, and then the signal is converted into a wireless signal and transmitted, which is received by the wireless network card.

Generally, the wireless router can drag 2 4 wireless network cards, and the working distance is within 50 meters, and the communication quality is very poor. Strictly speaking, this wireless solution is just a wireless network, and the working environment must be next to the wired network.

The price of a set ranges from 300 to 800.

The other is pure wireless, which requires communication equipment, such as satellite receivers, or mobile phones that can access the Internet, etc., these things are connected to the computer through a special data line, and they receive signals from satellite or wireless network services, but the speed is not very good, and the communication cost is super expensive. And satellite receivers and mobile phones are also expensive, usually ranging from 3000 to 5000, the advantage is that even if you are in the wilderness, you can also access the Internet (of course, you must have a computer).

Both of these solutions can be used on laptops and desktops, of course, desktops are inconvenient to move in the first place, and wireless doesn't make much sense.

**Cards with 6G data. Use it in 3 months, or use it up in a month.

Telecom 3G coverage is ubiquitous, 90% in the countryside, and mobile phones are connected to laptops to surf the Internet. Whether it is Mount Everest or offshore, the Tianyi 3G network is seamlessly covered. Mobile 3G provincial cities are not covered. China Unicom's 3G prefecture-level coverage has not been completed.

Unicom or Telecom can be, I think you need about 500m to 1g of traffic for ten hours a day, just look at it yourself and buy a proper card.

5G is enough In addition, what to upgrade the antivirus software should pay attention to controlling the traffic.

I think you should observe whether there is anything affecting the wireless network transmission in the dormitory, for example, you can adjust the channel of the wireless router to avoid interference from other wireless networks around the dormitory. Then adjust the position of the wireless router or wireless AP, adjust the antenna angle, etc.

Disable your own wireless card.

The strength of the signal is not necessarily related to the speed of the network, and there is also the problem of matching the pairing, which is not something that can be explained in one sentence or two.
