Poor broadband quality Can the broadband fee be refunded?

This can't be refunded, let's see if it's a problem with your computer! Move your computer to a place with a good signal to access the Internet (which is also a no-brainer).

No. Mobile broadband cannot be refunded, because mobile broadband is actually a contractual business relationship between the user and the mobile company, and the user pays a certain fee every month, and the mobile company will automatically provide network signal services. According to the contractual relationship, if the user unsubscribes from the broadband service before the contract expires, the remaining fees cannot be refunded.

If there is no agreement period and it is a prepaid user, then you can generally unsubscribe, and you can consult the business hall for details.

Broadband processing requirements:

To open 4G broadband for mobile phones, you need to bring valid ID documents and mobile phone cards, and queue up at the mobile phone business hall to handle it, and the mobile phone needs to support 4G network operation.

To open wired broadband at home, you need to bring a valid ID card to the business hall to make an appointment, or you can make an appointment at the online business hall. If there is no signal line of the operator, some will pull the line separately, and some cannot handle it, Yan Chunfeng needs to consult clearly in the business hall.

Check with the nearest operator's office to see if your place of residence is covered by the network (whether there are network resources). <

1. Yes, if the proprietor clearly states that it will not refund the reasonable refund request made by the consumer, or fails to refund the refund for more than 15 days from the date of expiration of the contract or the date of the refund request without an agreed period, it shall be deemed to be a deliberate delay or unreasonable refusal.

2. If a business operator provides goods or services in the form of advance payment, it shall clearly agree with consumers on the quantity and quality of the goods or services, the price or fee, the time limit and method of performance, safety precautions and risk warnings, after-sales service, civil liability, etc. Where goods or services are not provided as agreed, the agreement shall be performed or the advance payment shall be returned in accordance with the consumer's requirements, and the interest on the advance payment and the reasonable expenses that the consumer must pay shall be borne.

3. If there is no agreement on the refund, the refund amount shall be converted according to the calculation method beneficial to the consumer.

To return the broadband, you need to bring the original ID card of the owner.

Broadband. There is no strict definition of broadband. From a general point of view, it is the bandwidth that can meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing concept.

On January 7, 2015, the Federal Communications Commission (FCC) made its annual broadband progress report, in which the current chairman Tom Wheeler redefined "broadband", adjusting the original downlink speed of 4Mbps to 25Mbps, and the original uplink speed of 1Mbps to 3Mbps. The new standard for broadband networks in the United States: 25Mbps downlink and 3Mbps uplink.

Introduction: Broadband (English: broadband) in basic electronic and electronic communications, is to describe the continuation of the number or electronic lines contain or can handle a wide range of frequencies at the same time.

Broadband is a relative way of description, and the larger the frequency range, that is, the higher the bandwidth, the more data can be sent.

For example, in radio communications, a signal with a narrow frequency range can only send Morse code, and a large bandwidth is required to send high-quality **. The broadband of a TV such as a stocking antenna represents the ability to receive a larger number of channels. In terms of data transmission, the same ** line is used as the signal transmission medium, fiber optic cable is becoming more and more popular, modem can only send 64kbps of data per second, broadband ADSL and fiber optic modem can provide a higher transmission rate.

Principle: The traditional ** wire system uses the low-frequency part of the copper wire (frequency band below 4kHz). ADSL uses DMT (Discrete Multi-Audio) technology to divide the original ** line OKHZ to the frequency band into 256 sub-frequency bands with a frequency width.

Among them, the frequency band below 4kHz is used for transmission of POTS (traditional ** service), the frequency band from 20kHz to 138kHz is used to transmit uplink signals, and the frequency band of 138kHz is used to transmit downlink signals.

DMT technology can adjust the number of bits modulated on each channel according to the condition of the line, so as to make full use of the line. In general, the greater the signal-to-noise ratio of a sub-channel, the greater the number of bits modulated on that channel, and if the signal-to-noise ratio of a sub-channel is poor, it is discarded. ADSL can achieve a data transmission rate of 640kbps uplink and 8Mbps downlink slag.
