Fast connection via Wi-Fi through the D-Link DAP-1360

First and foremost it was necessary to choose the provider, I considered the following options: Beeline (Corbina), QWERTY, AKADO, StarNet, NetByNet, Onlaym and Infolayn.

Of all the widest channel on the Internet provided infolayn and NetByNet, but unfortunately next to mine district of Moscow to them was not connected and had to choose Onlaym — 51 Mbps inbound channel and an outbound 25. For a start I think this will be enough, but for the future it will be possible to get another channel, or to connect one or two providers.

I originally planned to establish a link between Moscow and his home Wi-Fi technology 802.11 n. For this I bought two access points D-Link DAP-1360.

200 and 300 meters

Tried to communicate at distances of 200 and 300 meters with a homemade antenna, but the speed was very low, at 3-5 Mbit/sec. At a distance of 5 metres the device’s data gave a speed of 80 MB/sec when transferring data.

The output was two to either search for a good antenna or find a more powerful access point. Since devices which produce for Russia have very low output power (usually not more than 100 mW), it was necessary to look for equipment from USA or China.

Ubiquiti UBNT NanoStation M5

And suddenly, in the Internet, accidentally found a very interesting device — Ubiquiti UBNT NanoStation M5, which provide real-life pumping speed up to 150 Mbps and operate at distances of up to 10-15 kilometers. And they work at frequencies from 4.92 GHz to 6.1.

At the moment they cost on ebay about 110 Euro with shipping, and in Internet stores from 4300р. Not to wait for them for months, I the next day bought them for in store comp from 2 pieces.

But you can buy on Aliexpress as with fast and slow delivery here.

The next day I tested the speed on a distance of 300 meters, the results have pleased me — 60 Mbps in both directions, then immediately I left the application to connect to online below after the installation of the access point already had access to the Internet.

Very pleased that the installers came 2 days later after I left a request on the connection and the channel is simply idle for 3 weeks.

It was hard to decide on friends from Moscow in a day will install their equipment, because everything is at different times either at work or at school.

Nanoscale consolidated ordinary sheet metal to the window frame and sent them to each other. To keep moisture and dust out of the inside of the case all the cracks were missed with the sealant.

When we’re all set, there was a small problem with the Internet settings, but after 5 minutes it worked and I went to Internet distribution.

Section Network I have configured as follows:

  • Network Mode: SOHO Router
  • WAN IP Address: DHCP (depending on the provider settings)
  • DHCP Fallback IP: IP address of DHCP server and DHCP Fallback NetMask: subnet Mask — you can view the status of the network connection when Internet is connected directly to the computer.
  • IP Address and Netmask — the IP and mask device in the local network.
  • And be sure to put a checkmark in the field Enable NAT, Enable NAT Protocol (all protocols).
  • You can also configure the port forwarding or put a tick next to Enable DMZ and specify the IP address that will redirect all incoming connections (for example a second gateway in the local network).
  • Multicast is not needed and I decided not to include.

The access point mode

Next, proceed to the settings of the wireless connection, first configure one device in access point mode.

I tried to change modes access point and the client places the most symmetric channel was, when in point mode, the access device that has taken the Internet from Moscow. A router working in client mode.

Thus, the access point settings:

  • Wireless Mode: Access Point WDS — in order to see real MAC addresses of the devices, not the client (NanoStation M5) select the WDS mode.
  • The new firmware has appeared at the bottom of the box of the WDS, do not forget to mention it.
  • SSID: the name of our network, if you wish, you can hide the SSID broadcast, putting a checkmark next to Hide SSID.
  • Country Code: United States, because if Russia’s choice many options unavailable. You can choose
  • Compilanse Test — then there will be no restrictions and will be available to all possible options and frequency. Relaxes check Obey Regulatory Rules, so you can adjust the transmitter power in any range.
  • Channel Width: 40 MHz, say that in bad weather the connection is stable at 20 and 10 MHz, but the speed will be lower several times. I have everything working fine in any weather.
  • Channel Shifting: if you want to use "is not a standard" frequency, you can mark this checkbox.
  • Frequency, MHz frequency, it is desirable that did not coincide with the frequencies of other devices nearby.
  • Frequency List, MHz: if you put this tick, the device will only work with the specified frequency needed in order to search for the access point, the client does not scan the entire range.
  • Output Power: output Power on both devices I put 8 dBm, since the distance is small, and will not clog the air. You can safely reduce the power of another couple decibels. A lot of power can badly affect the speed of data transmission, a value is chosen experimentally to achieve optimal speed and signal level in the range of 60-70 dBm.
  • And of course don’t forget about the encryption setting, I put WPA2-PSK and also enabled the MAC filter.
    Client configuration is similar:
  • Wireless Mode: Station WDS, the new firmware don’t forget to check the WDS.
    SSID: the name of our network
  • Lock to AP MAC: MAC address of the access point (Access Point), you can see in the Main tab, WLAN MAC.
    What kind of option DFS I have not yet figured out.

Now you can fiddle with advanced settings, open the Advaced tab:

  • Distance: set the distance that the signal was the best, and delays as little as possible. There’s even a formula to calculate the ACK Timeout: 23 + distance in meters / 150.
  • Multicast data: allow multicast between access points.
  • Signal LED Thresholds: to disable signal indicators, set all values less than 45.

Next, open the Services tab:

  • Put a tick next to Use Secure Connection (HTTPS) and change the ports 80 and 443 on any other, not to Shine in the web interface.
  • It is also desirable to change the port from SSH and Telnet servers (if included).
  • Put a checkmark in the Enable NTP Client and NTP Server, enter the following: ntp1.dlink.com for sinkhronizatsii time.
  • AirMax technology I initially disabled, wrote somewhere that because under heavy load on a channel may increase pings: In practice, the opposite was true, so this option I suggest to include, the only way I have reached maximum speed and normal operation at maximum load on the channel.

The measurement of the speed and ping

Now the most interesting, the results of velocity measurements:

Depending on the weather, the speed can vary, mostly this affects the speed (from the client to the base station). Given the fact that there is a very large margin of speed that’s enough for me.

When the point, distributing the Internet worked in access point mode the speed was around 60-70 Mbps and upload speed of 110-130 Mbps. Changing modes sometimes the speed has become practically symmetric.

And it is at a rate 51/25 Mbit/sec. Ping to Yandex 3-4 MS, but because of the lack of provider onlaym peering between large networks (e.g. Corbin) traffic to some Russian sites passes through Europe, what’s not to like online gamers.

By the way, after a week-long test NanoStation M5 I noticed that one of the device start to reboot. I tried to change the firmware, power supplies, modes of operation, change points in some places — nothing helped.

The next day, wrote in an email to the shop where I got both the access point and I was told that I can drive up and place something will come up.

Riding up to the store I changed the access point to the new, despite the fact that the lower part was smeared with silicone (it is very difficult to scrub), for which many thanks to the shop comp2.ru!

From the time of this writing it’s been 2 years and the connection is still working without failures and manual reboots, I.e. completely without physical access to both access points. A couple of times a year went to the web interface for firmware updates because newer versions have new functions.

The Internet in our "village" 5 years later appeared, in speed and tariff is cheaper than in Moscow across the street.

So at the moment the wireless connection works as a backup channel and is rarely used. For the year accounted for 3 times to switch for a day on the backup channel when our local reputable provider problems, to the astonishment technical support told us all right, etc., the next day everything was back to normal.
Through this channel until you have to drive traffic SIP telephony, because telephones do not like change IP addresses or reconnection (for example, at the end of the session PPPoE 24 hours) and Moscow is now pulling Internet from us.

As I recall airMAX Quality and airMAX Capacity during data transfer reached almost 100%.

The Internet I now have 100 Mbit/sec in both directions, speedtest.net of course, this speed will not show. And when we had been suffering with advanced technology ADSL.
