The network and broadband of the 90+ square meter small house that lived in the past did not have much problem. The wifi signal was basically covered. Therefore, when the 180 square meter new house bought the year before, there was no pre-embedded network cable. It was intended to cover the whole house WiFi, leaving only one From the weak box to the main bedroom network cable. Before the wifi signal through the wall there is a psychological expectation, the basic 2 wall signal will decay a lot, the solution is to add a routing wireless bridge in the living room, the signal is plausible, the living room and the next TV to watch online video no problem, is to use It's annoying to read the high-definition movies on the TV directly from the host computer from time to time. I am now master bedroom routing bandwidth 100m, the actual bandwidth of about 90m, the download can reach up to 10m more points, with wireless bridge to the living room, through 2 walls after the actual bandwidth of routing 2 about 10m, download about 1m more, and very Unstable, sometimes only a few hundred k download, watching LAN high-definition video is not strange card, hey, the house is too big and hate! Before you learned about power cats, but they never dared to start, one is expensive, and the other is the powerful signal attenuation. Many of the 100m200m power cats that sell more than 300 yuan are 100m in Lan interface, and can achieve 20- in the case of low line interference. The 30m bandwidth is good, but in most cases it can only reach 10-20m. This bandwidth and my current wireless bridge promotion is not big, there is a P use ah. I stumbled upon this French 500m cat, the French custom model EVHP74500WF, the Lan interface is still Gigabit, the CPU is AR7400, much stronger than those 200m 6400 chips, the price is very much less than 50 talents, bought a pair And the seller bargained 95 transactions, this price is still plausible, but the effect has to be actually measured after installation to know. Anyway, it's cheap, let's say, even if 500m bandwidth is attenuated to 20%, there is 100m bandwidth. If you look at online reviews, this machine can run up to 70% of the bandwidth with less interference. After arrival, it was discovered that it was completely new. The plastic film on the surface of the machine was intact and the serial number was corresponding. The bottom of the machine should be made in china. Originally in the seller's Tu Liben thought that this stuff is a little small. When actually receiving this item, your sister's size is bigger and bigger than a normal 5-inch mobile phone. 1/3 of the thickness, plus the protruding plug, is actually very big. It's too unobtrusive to feel that the wall is too big. The installation is super simple. I have found empty wall plugs. Waiting for the red light to turn green indicates that the signal is normal. I don't need to use palletizing. The main thing is to test the wall plug and the plug-in cable. Great influence. As the house was renovated, the strong electric wires of the master bedroom and the living room were separated. Therefore, an air switch was crossed. The air switch had the greatest impact on the electric cat, and the second was the socket with the lightning protection function. And the charger, so the seller also explained that using a wall plug should not use a row plug. Master speed test, bandwidth 90m, Another wall plug speed test of the master bedroom, with more than 80m bandwidth, more than 10% loss, and a delay of 60ms Living room speed test, bandwidth more than 50m, loss of nearly half, over an air switch, the loss actually increased, the delay is the same 60ms With about 30-40m bandwidth, about 3-4m download, but the speed is very stable, Now Kodi uses Kodi to connect to the local area network to see 720p and 1080P single movie files within 8G. 65-inch TV with kodi LAN directly connected to the master bedroom computer to read the hard disk, movie library finally useless I can't say that big sisters live in G, H, and I Conclusion: The primary condition for power cat purchase is that the Lan interface must be Gigabit. This gadget is very costly. Basically, an air switch will lose half of the bandwidth. Nowadays, a large row of air switches in the house is very normal. Next, can insert the wall plug to insert the wall plug, I was unable to insert the plug, the main thing I bought this product is too big to occupy the jack, plug it in the basic wall plug on the waste, with excess wall plug Can be considered. Finally, the power cat is a last resort, in the decoration can be wiring on the wiring, and must be cloth six lines, so as to play the best performance of the network, do not rely on wifi bridge, wifi relay and the like, do not rely on Spectrum.
