1. yes! All kinds of digital currencies on the market are essentially a game of playing drums and spreading money, plus a pyramid scheme! It's all scams carefully packaged by swindlers!
2. When the light signal lamp of cat disk turns red or flashes, it indicates that the optical fiber signal cannot be received, which is usually caused by the following conditions: when the light signal lamp of cat disk turns red or flashes, it indicates that the optical fiber signal cannot be received, which is usually caused by the following conditions: when the light signal lamp of cat disk turns red or flashes, it indicates that the optical fiber signal cannot be received, It is usually caused by the following conditions:
3. the limited or no connection display of local connection on the computer is related to the network server and network card. Anyway, it's a network problem. It doesn't have much to do with computers. It doesn't affect the system. You can ignore it. If you are really bored, you can remove the option of "notify me when there is no connection" in the local connection settings of "network connection", which does not affect the access to the Internet
for intranet, it's better to specify an IP....
route sharing Internet access
if it's route sharing Internet access, local connection should be used. The TCP / IP protocol of your network card is set to automatically obtain the IP address. However, there is no DHCP server in your LAN that can let your machine obtain the IP address. In other words, the router DHCP can not correctly resolve the IP address and does not assign the IP address. So your IP address is not available. Of course, it is restricted or disconnected
solution
1. Set an IP address for each network card. On XP: start - connect to - show all connections - select the restricted or connectionless network card, properties - select the Internet Protocol (TCP / IP) in the "this connection uses the following items" box, properties, use the following IP address, set it to the IP address of the same network segment as your router (if you don't know, set it to 192.168.1.2-200), That could be the IP address of your router. This problem is solved. For example:
IP address 192.168.1.102
subnet mask 255.255.255.0
gateway 192.168.1.1
the preferred DNS and standby DNS are searched from other computers, or from the Internet to find the local telecom or Unicom DNS, them to fill in, and click OK
2. Check whether the network cable is connected normally by your computer switch, router and cat. If there is a line detector, use the line detector to check whether it is connected. If it doesn't work, reassess the head. The most important thing is that your crystal head is made by professionals (if there is a problem with the crystal head, you will be very upset). If there is no problem, in the computer to unload your network card, in the device manager to re point operation, refresh, is to detect hardware changes! Let's see if your local connection is normal. If it is still an exclamation point, you can right-click the local connection property and click TCP / IP first. Then click to use the following IP address, input:
IP address 92.168.1.102
subnet mask 255.255.255.0
default gateway 192.168.1.1
then click to use the following DNS server address, input local telecom or Unicom DNS, confirm
3. If the network line condition is not very good, for example, the line between the computer and the switch is long, the line is connected to the level switch, the line has a connector, and the network connection is normal, the IP address will be automatically obtained to show that the local connection is limited or no connection, and the IP address can not be connected to the Internet manually, you can set the network card configuration. Open the local connection and click properties. When connecting, click Configure on the right side of the list of network card names below, then click Advanced, select full plex mode, select 10 full mode from the drop-down menu on the right, and confirm.

in the "start" menu, and then enter CMD
in the command prompt box, and enter "Netsh Winsock reset & quot; Press enter
takes effect after restarting the computer
6. If the mobile phone shows that it is connected to the wireless network, but still unable to access the Internet, Samsung mobile phone generally recommends the following operations:
1. Turn off the mobile phone, restart the router, and then connect to the wireless network again
2. Please confirm the transmission bandwidth of the router (the bandwidth supported by the router supporting 802.11n is 40MHz, it is recommended to set it to 20MHz), and confirm again whether the router network is normal
3. Confirm whether IP address filtering / MAC address filtering is set in the router
4. If you still can't access the Internet via WLAN, it is recommended to try static IP mode: setting -- WLAN - select a wireless hotspot - display advanced options - check - slide down the screen - IP setting - static - IP address / gateway
5. Try connecting to other routers
6. Try to restore the factory settings after backing up the important data of the mobile phone
if the problem still exists, it is recommended to bring the purchase invoice, San Bao voucher and the mobile phone to the service center for inspection by the engineer.

7. If the broadband cannot access the Internet, please confirm whether the broadband is suspended e to arrears. If so, please recharge first
if the mobile broadband fails e to non arrears, it is recommended to operate in the following ways:
restart the optical cat, plug in the optical fiber connector again, and then test online
judge the status of light cat indicator, such as Wan indicator is always on or flashing when the port is connected with the cat normally
remove the router, create a broadband connection, and reconfigure the router
if the above methods still can't solve the problem, you can call local 10086 for broadband report.
