Q:
My laptop is HP dv5t, now the problem is that when I get to Internet at home, as through wireless router, I found when connecting network, the speed is extremely slow, what’s the problem? How should I solve the problem?
A:
1. Few reasons for low network speed:
1) Network problem
The server bandwidth of the target website you want to connect is not enough or the loading is too big. The solution is also quite easy, please change another time to visit or just change the target website.
2) Network cable problem making network speed slow
It is known to all that twisted-pair is made of four pairs of wires twisted together closely by strict regulation, which is used to reduce the influence of interference and background noises. Meanwhile, in T568A standard and T568B standard, only the 1, 2 and 3, 6 cables of the twisted-pair are in use, among these wires, 1 and 2 are used for sending out, 3 and 6 are for receiving. Besides, 1 and 2 must come from one pair, 3 and 6 must come from one pair too. Only in this way, it could avoid interference to the greatest extent, ensuring the data transmission. If the twisted-pair is broken or cracked, then this or that problem will occur.
3) There’s loop in the network making the network speed slow
When the network nodes involved are not too many, the structure is not that complicated, then such symptom rarely happens generally. But in some complex network, there’s often extra circuitry for backup, if it’s connected by accident, loop will form. If there are few circuitries con
