WiFi connection but not the internet how to solve

There are a number of reasons for this, and there are probably several types of analysis: 1 network problems, such as dial-up failure, 2 the router is broken, such as Lightning burn out; 3 The routing settings are biased, such as the setting of AP Isolation (this point Lei Feng Network previously reported that the Nets used); 4 The distance is too far, signal strength is not enough.

1, 2, 3 points better understanding, the 4th is not so clear. When the distance is too far, what is the link between the routing and mobile phone? Not even, why can't the internet?

In general, the WiFi experience, in addition to being affected by bandwidth, depends on both hardware-routing and terminal wireless performance. The route should be able to send the signal far away, but also to the farther back of the signal recovery, the accurate statement is the signal launch and reception capabilities. Mobile terminals are also.

The farther away the wireless is, the more performance it takes, and the slower the speed. For example, 2.4GHz Wireless routing, the most recent is 802.11 n 150Mbps full blood rate, far more likely to become 802.11 g 54Mbps rate, farther is lower, the lowest is 802.11 2Mbps.

Extremely enterprise Technology CTO, open Source Intelligent Routing Tutorial (Makerrouter) Initiator Hoowa told Lei Feng Network, routing performance is usually not the same, most routes in the launch capability will be stronger, but also some of the ability to receive better. This causes the user to use the difference, a very common example is the operator WiFi, we often encounter "connected, but can not surf the web, even the landing page can not brush out" problem, in fact, from these routes to receive the signal's ability to weaker.

At the other end, the handset/terminal's ability to send and receive is too weak, so it is rarely said that general pen > flat > Mobile phones. However, some players will buy a strong network card on the computer, so that they can connect to a farther place WiFi, similar to the self-made signal gain network card is also common.

There is also a small experience that has to be mentioned, when the weak signal connected WiFi, the wireless performance is very damaging, because it will occupy more transmission time. The solution is to turn off the low speed beacon signal, which can effectively reduce the burden.

But this trick is not good for ordinary people, because it involves wireless drive, not simply brush a openwrt system can be adjusted. PS: If you want to play with children's shoes, you can pay attention to the progress of the Makerrouter project, this fully open source routing project will involve the driving side.

So, the next time you encounter the "Wi-Fi and can not access the Internet" situation how to do? According to the front 1, 2, 3, 4 point of the investigation chant.
