1, the router problem, this is the most common problem, it may be just a moment of connection into an infinite loop, the simplest solution is to plug the router power interface, let the router restart, why the phone can not connect to wifi, 90% is due to Router problem, in addition to the router settings function, the permissions are set to modify the router settings, of course, if you do not know how to set up, you can directly restore the factory settings.
2. Multiple devices are connected at the same time. The simultaneous connection of multiple devices is due to the large number of users, which exceeds the upper limit of the router connection. This causes the IP conflict even if the router is connected to the Internet, or cannot connect to the wifi. Needless to say, the solution to the situation.
3, baseband or ROM problem baseband is the module responsible for communication on the mobile phone, often a mobile phone has multiple basebands to choose from, if you brush an inappropriate baseband while brushing the ROM, it may cause your wifi The connection is not normal, even if the text message cannot be sent out, the phone can't be sent out. This is the direct way to brush the ROM. This is the most direct way to deal with it.

A blackboard (also known as a Chalkboard) is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate, known, when used for this purpose, as chalk. Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone.
A blackboard can simply be a board painted with a dark matte paint (usually black, occasionally dark green).Matte black plastic sign material (known as closed-cell PVC foamboard) is also used to create custom chalkboard art.Blackboards on an A-frame are used by restaurants and bars to advertise daily specials.
A more modern variation consists of a coiled sheet of plastic drawn across two parallel rollers, which can be scrolled to create additional writing space while saving what has been written. The highest grade blackboards are made of a rougher version porcelain enamelled steel (black, green, blue or sometimes other colours). Porcelain is very hard wearing, and blackboards made of porcelain usually last 10–20 years in intensive use.
Lecture theatres may contain a number of blackboards in a grid arrangement.The lecturer then moves boards into reach for writing and then moves them out of reach, allowing a large amount of material to be shown simultaneously.
The chalk marks can be easily wiped off with a damp cloth, a sponge or a special blackboard eraser usually consisting of a block of wood covered by a felt pad. However, chalk marks made on some types of wet blackboard can be difficult to remove. Blackboard manufacturers often advise that a new or newly resurfaced blackboard be completely covered using the side of a stick of chalk and then that chalk brushed off as normal to prepare it for use.
