Shutdown of the Internet sometimes is capable to become the cause of a nervous breakdown, and the known case with Anton Uralsky - to that an example. But what becomes the reason of the shutdown of the Internet?
Instruction
1. In a case with ADSL of the reasons of loss of communication can be a little. In all to the known phonogram the operator of support desk of provider was absolutely right: as the IP address to the subscriber is selected dynamic, once a day are really disconnected on purpose ekgo changes. And if the modem combined with the router is used, then the subscriber quite can this gap and not notice, to a poskol after it automatic reconnection (it takes about thirty seconds) is immediately carried out, and the computer nothing is displayed.
2. If at access through ADSL at least one telephone set is connected not through a splitter or the microfilter, and directly, it will cause not only unpleasant hissing in a tube at the working modem. At an incoming call and also at those moments when the user of the device picks up and puts the phone or dials number, there will be reconnections. However, during the conversation the access all the same will not be closed.
3. At access through dial-up the rupture of communication at accidental removal of a tube on parallel phone will occur surely. Reception of an incoming call in such situation it is impossible as it at the working modem number is occupied. Also both the modem, and the equipment of provider sometimes break link at the moments when passing of a signal worsens. It is necessary to be reconnected, sometimes not from the first, because of employment of number.
4. In normal GSM network the voice traffic is given a priority before the data transferred under the GPRS protocol for which channels, free are used at present. When the subscribers wishing to talk become too much, there is no clear channel left, and Internet access is interrupted. Also it is interrupted and when its owner and also during transmission and reception of messages, sending USSD commands decides to speak by phone.
5. In 3G-networks a situation more favorable. Their throughput is considerably improved in comparison with GSM networks, and data transmission and voices are possible at the same time. Traffic in such network has smaller prime cost, as caused sharp depreciation of unlimited rates for the mobile Internet. But if the subscriber is in the movement, it should switch between base stations, some of which support 3G, and others - are not present. At the moments of change of stations sometimes there is a temporary termination of access. And operators sometimes periodically make a forced rupture of communication.
6. At access through WiFi sometimes already in ten meters from the router the reception becomes unstable. Radiation with a frequency of 2.4 GHz on properties something reminds normal light. It is easy to block it a wall and even a palm.
7. Failures at Internet access via the twisted pair cable can be caused by faults as on the party of the subscriber (the damaged network interface card), and on the party of provider. Sometimes the damaged cable (and, the place of damage on the section between the subscriber and provider can be anywhere) and also the preventive actions which are carried out by provider is the reason. And if after change of the network interface card even at implementation of the correct settings the access is not resumed, presence at provider of control to the MAC addresses is the reason. It is enough to report the new MAC address in support desk, and connection will be restored.
