Contactless cards in the Gomel region. Troubleshoot Wi-Fi connection problems

There has been talk about a contactless payment system for a long time, but so far it is just developing. A surge of interest in this “new product” was caused by an advertising video in which Alexandra Gerasimenya deftly pays by waving her reticule. We inquired about local realities.

According to Belarusbank, approximately 8,200 people in the country now have their contactless cards. Plus swimmer Gerasimenya. The share of the Gomel region is still small. There is also no consolidated information yet about where you can already pay with a contactless card: banks are still forming these lists.

The fact is that “contactless” infrastructure is now being independently developed by different banks together with trade and service enterprises. At the same time, it makes no difference to the client which bank installed this or that terminal - payments (ideally) are accepted equally from cards of all banks, no interest is charged.

The regional administration of Belarusbank agreed to clearly show how it works. Everything is quite simple, but, as it turned out, in practice (if you are not a world champion) it is still not enough to wave your purse to pay.

For a test drive we use the terminal that is installed in the local buffet. Bank employee Tatyana is helping us.

The terminal and the card must have corresponding symbols resembling a Wi-Fi icon rotated 90 degrees - they inform about the possibility of contactless payment.

- It won’t turn out that the cashier entered the amount for an unauthorized buyer, you passed by with a contactless card and your money was debited?

- Will not work,- Alexey Delikatny, head of the bank payment cards department, is confident. - Firstly, the range is small, the distance between the card and the terminal should be two centimeters, no more. Secondly, payment by contactless card must first be approved by the cashier. In general, it is easier and faster than paying with cash or a “contact” card. Plus, you don't let go of it. It is safe and convenient, for example, at a gas station, at ticket offices.

After the cashier has entered the product details, Tatyana brings the card to the terminal.

A beep sounds: the mineral water has been paid for.

We check whether it will work through the wallet.

The terminal beeps approvingly. Another bottle of water goes to bank employees.

Bankers say it is not only convenient, but will soon become fashionable. The presence of a magnetic stripe and chip allows you to pay in regular terminals. At Belarusbank, a contactless Visa card (with a package of other services) will cost 95,000 rubles. Manufacturing will take up to 10 days.

If your smartphone runs on the Android 5.0 Lollipop platform and you connect to the Internet via Wi-Fi, you may encounter a problem with an exclamation mark next to the usual Wi-Fi icon. What does it mean? How to solve the problem and is it necessary to do it? Let's start with the fact that the symbol "!" indicates that it would be a good idea for you to find out more about the wireless network that you decide to use - the warning is associated with it. There may be many solutions to this problem, but so far we have found the only way that really works.

So, the problem is related to the wireless network. To solve this, we suggest setting a static IP address for that particular Wi-Fi connection. This means you need to know the available address on the local network, the gateway address, and the DNS addresses (DNS1 and DNS2) for the network. For the latter, you can use the default Google DNS addresses 8.8.8.8 and 8.8.4.4. We're not saying this is the best solution, but it works.

Procedure:

• Go to " Settings" on your Android device, find the Wi-Fi subsection.

• Find the network you are currently connected to, press and hold its name, then select “ Change network».

• At the bottom of the screen, select " Show advanced features", then select " IP parameters"and further" Static".

• Enter the required network information in the fields provided and click " Save" Once you do this, reboot your device. When the device reboots, take a look at the notification panel and make sure that you were able to connect to the same network without an exclamation mark indication.

It is quite possible that you will have to do these steps repeatedly - for each of the wireless networks that you use. But usually updating the operating system to Android Marshm solves this problem once and for all. Until then, a simple static IP address will protect your device from " ! ".

A few days ago I changed my Sberbank bank card due to expiration. Having received the newly released MasterCard, I noticed that it was practically not much different from its predecessor. But the “Wi-Fi” icon appeared in the upper right corner. I must admit, I was very interested in him. No, I know about contactless payments, but I didn’t think that they had already reached regular bank cards. But first things first.

Contactless payment system

Technological progress does not stand still and for the convenience of users, a contactless payment system is being actively implemented today. Most likely it will be extremely popular in the future! Now, carrying out payment transactions does not necessarily require inserting the card into the reader - it will be enough to simply bring it to the ATM card reader or to the terminal at the cash register and the payment will go through “like clockwork”!

This entire system is built on the use of NFC chips, which are now even built into plastic cards of Visa, MasterCard and MIR banks. The only exceptions are Maestro and Visa Electron. The Wi-Fi icon on Visa cards is usually located in the upper left corner, and on MasterCard cards it is in the right. By this WiFi sign you can recognize whether the option is supported or not.

Main advantages contactless payments are as follows:

• Convenience! This is the main plus. No need to insert the card into the reader and enter a PIN code! Just bring it to the terminal and the money starts flying!
• Safety! Your card is always in your hands. No one will see her details either! Data transmission is carried out over a very short distance and it is almost impossible to intercept the process.
• Speed! Due to the fact that some of the actions when making a payment disappear, the speed of payment transactions is reduced by at least a third!

How to use a Sberbank card with a WiFi sign?!

In order to make a contactless payment, you must first make sure whether the terminal supports contactless payments or not. To do this, they must have one of these logos (or several at once):

We wait a couple of seconds while the data is being exchanged. As soon as a message appears that the operation was successful, you can put the card with the Wi-Fi icon back in your wallet or purse.

Almost all routers or modems have indicators. Most often they are simply called light bulbs. Their task is to inform us about the status of the router, device connections and the operation of certain functions. Based on the status of the indicators, we can immediately determine whether the router is distributing Wi-Fi, whether it is connected to the Internet, whether the LAN connection is active, etc. The indicators can also determine whether the router is malfunctioning. In this article we will look at the indicators on TP-Link routers.

On almost all TP-Link routers, the indicators work the same. But there are small changes on the new models. They may light up in a different color (for certain errors), there is no gear indicator (system, SYS), and there may be two Wi-Fi indicators (separately for 2.4 GHz and 5 GHz bands).

Many people are interested in the question of how the lights on TP-Link routers should light or blink during normal operation of the device. What does each indicator mean and what to do if, for example, only the Power indicator is on, all the lights are on, or the Wi-Fi icon is not active.

First you need to figure out what's what.

What do the indicators on a TP-Link router mean?

I think it would be wise to consider two TP-Link routers. I already wrote above that there are some changes in the new models.

So, first, let’s look at the indicators using the example of the popular TP-Link TL-WR740N model.

What are they responsible for and how should they work:

1. Power indicator. When the router's power is turned on, it lights up. Disabled - does not light up.
2. This is the system indicator (SYS). It has three modes: off - system error, on - the router is loading, or system error, blinking - everything is fine, as it should be.
3. WLAN wireless network operation indicator. And if it is not lit, then this means that the Wi-Fi network is disabled by a button on the router, or in the settings.
4. LAN ports. Off means nothing is connected to the port, on means a device is connected but not active, blinking means data is being transferred.
5. Internet connection indicator (WAN). The display is the same as in the case of LAN. On some models it may glow orange when not (or not configured) Internet connection.
6. WPS. Flashes slowly – the device is being connected via WPS. Flashing quickly - the device could not connect, the waiting time has expired. Off – the function is inactive. Lights up when the router is loading and 5 minutes after the device is successfully connected.

And using the example of a newer router, TL-WR942N.

I will not describe all the indicators again. Let's look at just a few of the changes.

• If you have two Wi-Fi indicators on your TP-Link router, then they are responsible for indicating the operation of the wireless network in different bands: 2.4 GHz and 5 GHz.
• There may be one LAN icon. It is active if at least one device is connected via cable.
• Routers with a USB port have a corresponding indicator (at number 6 in the picture above). Doesn't light up when nothing is connected via USB, flashes when the device is being detected, lights up when the device is detected.
• WAN indicator (Internet, in the form of a globe) lights up orange (red) when the cable to the router is connected to the WAN port, but there is no connection to the Internet. The router cannot connect to the provider. As practice shows, most often due to settings. This is a very popular problem, I’ll talk about it later in the article.

Let's take a look three main problems, which users of these routers most often encounter, and identify them by the lights on the device body.

Orange or red WAN (Internet) indicator

It's not a broken router or anything. The orange Internet indicator on the TP-Link router means that the cable to the WAN port is connected, but there is no connection to the Internet. That is, the router cannot establish a connection with the provider.

And if the Internet works when the cable is directly connected to the computer, then in most cases it is necessary to configure the router correctly. Specify the connection type and set all the parameters that your Internet provider should give you. You may also need to clone the MAC address.

Why doesn't the Wi-Fi icon (light) light up on my TP-Link router?

There are such cases. During normal operation (when at least one device is connected and data is being exchanged), the wireless indicator should blink. If it does not light up at all, it means that the router is not broadcasting the wireless network.

Try rebooting your router first. If it doesn’t help, then check the Wi-Fi (Wireless) On/Off button, which is found on many models. You need to press it and hold it for 3 seconds.

If the Wi-Fi indicator does not light up, then in the "Wireless Mode" section, check whether wireless network broadcasting is turned on. If this does not help, or in the settings there will be a message that to turn it on, use the switch on the device body (and it's definitely on), then you will have to reset the settings. And if resetting doesn’t help, you’ll have to take the router in for repair or under warranty.

Only the power indicator is on, or all lights are on/blinking

It happens that the indicators behave strangely, for example, even some time after being turned on.

Or after turning on the TP-Link router, all the indicators light up and do not go out. It also happens that all the lights blink at the same time (this is recovery mode).

Most likely, this is a software glitch or hardware failure of the router.

You can try it. Especially if this problem appeared during the firmware update process. Perhaps something went wrong, or you uploaded the wrong firmware to the router.

If the problem persists, the router does not turn on, does not boot, then there is nothing left to do but contact the service center. Possible under warranty. And if the router is not expensive, and even old, then it is better to buy a new one.

If you're having problems connecting to your Wi-Fi network (such as authentication or connection stability), try the solutions below. You can tell if there's a problem by seeing an exclamation mark next to the Wi-Fi icon on your Pixel or Nexus device's screen.

After each step, try connecting to the network again and opening any website on the device.

Step 1: Check your settings and reboot your device.

Step 2: Determine the source of the problem.

• Device
  Try connecting to the Wi-Fi network from another device, such as a laptop or a friend's phone. If the connection is successful, the problem is likely with your device.
• Net
  Try connecting your device to a different Wi-Fi network, such as at a café or at a friend's house. If the connection is successful, the problem is most likely on your network.
• Internet
  Does your device connect to the network but can't access the Internet? The problem is probably related to your Internet connection.

Step 3: Fix the problem.

Troubleshooting device problems

Troubleshoot network or internet connection problems

Restart your Wi-Fi router or modem

If you have access to your router or modem, turn it off and on again. Here's how to do it:

1. Unplug your router or modem's power cord from the outlet for 15 seconds.
2. Reconnect the power cord to the outlet.
3. Make sure all cords and cables are securely fastened on both sides.
4. Wait a few minutes until the lights on your modem or router start working as normal.

If the lights are not blinking as instructed, the problem may be with your modem, router, or Internet connection.

In this case, contact your network administrator or Internet service provider. The problem may have occurred due to a power outage or internet connection reset.

Sign in to connect to a public network

Typically, to use a public Wi-Fi network (for example, in a cafe or airport), you must sign in on the authentication page. Otherwise the connection will not be established.

If this page appears when you connect to the network, sign in or accept the terms of use.

If the authentication page does not open, follow these steps:

• Check to see if a login notification appears.
• Try opening a new web page in a new window.

If this doesn't help, try connecting to the network again. Here's how to do it.
