The landlord's home was renovated in 2011. At that time, the small town network still used ADSL as the telephone line. During the renovation, a dual-port network module was installed in the corridor outside the door. The entrance line was a telephone line and a Category 6 network cable. In those days, it was thought that the locals, that is, LAN subscribers, did not consider the possibility of fiber optics. The result was that the landlord had completed light changes several years later when the landlord checked in. Fortunately, the building host intelligence, bought a wall-mounted weak box hanging in the corridor, the light cat weak inside the electric box. No power supply was used to directly connect the 220V mains power with the telephone line. Fortunately, the telephone line used in the year was a copper wire. The light cat that was loaded with a few W was under no pressure.
All the houses in the house were Gigabit Category 6, two modules for the study and two modules for the living room. However, the bedroom does not have a layout module. The result is that the bedroom's Internet TV WIFI signal is not ideal, and there is too much interference around the 2.4G channel. It is planned to replace the router to make the TV in the bedroom use 5G band.
Locally purchased aluminum racks are ready to put some network equipment on it.
Need a little change.
Shaped appearance.
Briefly explain the device, C301 brush OPENWRT do a routing, R7000 brush Merlin do two routes. Why not use R7000 as a level because my broadband is China Unicom's 20M. Fortunately, we can dial more. OPENWRT can be dialed more concurrently. I tried to dial up to 200M. Instead of using the R7000 as an AP, the R7000's over-the-wall function is disabled when it is set to the AP mode. The AP mode is equivalent to the R7000 being a switch and does not have NAT forwarding. All R7000s can only be wronged as secondary routes. Because usually 4 dials are enough, in order to save space, the original WNDR 3800 is replaced with C301. It is a 100M network port, and more than 4 dials are meaningless.
Intended to be so arranged, a 120G notebook hard drive is used by Thunder Download. A 1.5TB mobile hard disk access R7000 open Samba service to do a simple LAN sharing. Although the R7000 can be downloaded from the Thunder remotely after downloading Meilin, but over time, the CPU and memory are almost fully loaded, or even suspended animation. Therefore, it is still clear that the division of labor. After all, routing is a route.
R7000 heat is not small, intends to install a 12CM cooling fan at the bottom of the rack, here is an ADDA disassemble power fan, the advantage is that 5V can still run, and almost no sound.
Change to USB interface, plug in the C301 routing USB port to take power.
The cooling fan is fixed to the bottom of the rack with hot melt adhesive.
The landlord's router hiding position is absolutely impossible if no one can find it, yes. In a narrow space above the ceiling.
In the interior of the ceiling, in fact, the horizontal space is quite large. It is highly compact and does not perform well during maintenance. At this point the route is WNDR3800, also brush OPENWRT firmware more dial, in fact, WNDR3800 wireless is also quite awesome, more than 140 flat basically no dead ends. However, it's 5G signal is not flattered, never used the original firmware, after the openwrt brush as long as a wall of 5G signal only one grid.
The crystal head is pressured by the landlord himself, but the six shielded crystal heads are not used to shield the network cables. The speed of copying files under actual measured windows can reach the limit of Gigabit. Fortunately, once again, if the fabric of the 100Mb network cable can not play well.
The reserved power position inside the ceiling, the power switch is controlled by a separate switch on the corridor wall. You can turn off the power first under maintenance. Plug in the power socket is the power of the light cat, then forgotten to leave the power outside the door, can only use the phone line instead, but fortunately, the light cat power is small. Otherwise, the wall will be punched again.
After the equipment is put on the shelf, the vertical space is too small. The three antennas of the R7000 can only be placed flat. How do you always feel that the upstairs occupants receive better signals than at home?
This is how I used the power. R7000 uses the original adapter (12V 3.5A) C301 routing because it is 5V power supply, so directly insert a USB to DC interface charging cable from the R7000 USB2 jack (DC line is 12 copper up to 1A current The cooling fan on the underside of the bracket is plugged into the USB port on the C301, which saves one adapter. Mobile hard disk connected to the R7000's USB3 port, the actual measurement of the copy speed of about 65M or so. Thunder download Bao original adapter, notebook with easy to drive the line to download the treasure.
Power measurement, R7000 5G signal has two compartments behind a wall. How do you say 2.4G signal? In the past, the WNDR3800 had two cells where the R7000 was full. It seems to be of little significance... I thought the tossing was over. As a result, the test found that the TV was playing smoothly with the 5G signal, and the 2.4G signal of the mobile phone couldn't open the page intermittently. It immediately reminded me of the legendary Merlin firmware wireless disconnection. In order to determine let the TV receive 2.4G signal. As a result, the flow was interrupted once every several minutes, about 5-10 seconds each time. Equivalent to 2.4G waste, and it is not possible to use 5G for all wireless devices. Can not be reconciled to brush different versions of Merlin, toss half a day after the conclusion is no egg, any Merlin version 2.4G is off, regardless of the transmission power is adjusted to large or small, channel and regional settings for China or the United States, the difference Only the interval between the interruption of the flow ... In order to determine the hardware is not a problem R7000, directly brush back to the original firmware, and finally 2.4G stable, but the original firmware USB sharing difficult to use, can not over the wall, how do I Feeling if there is Merlin firmware R7000 simply is not worth buying...
The end result is that continue to replace the original WNDR3800 with ... R7000 put in the apartment and brush back to the original replacement of the routing in use ...
Edit this article when Merlin revised firmware out of the 380.61-X7.0 version, it is said that the wireless part of the direct use of the V original firmware, the previous Merlin revision firmware modified the wireless part of the code, I do not know the 380.61-X7.0 Merlin firmware There is no 2.4G cut-off phenomenon, and this cut-off seems to be very strange, some brush firmware has not been cut off? But I'm not going to toss it anymore. If I don't solve it, I'll dismantle it again... Heart...
