Which channel is on direct TV
Change WLAN channel
The WLAN channel is an important factor for the speed of your wireless Internet. If your internet is slow, it is often because there are too many devices in the same WLAN radio channel or in adjacent frequency ranges.
It is enough if you live in a densely populated area or in a large apartment building. The solution to this problem is simple. You only have to change the WLAN channel and, if necessary, change the frequency range. We'll explain how it works.
The "emptier" your WLAN channel, the faster the data rate.
Change WiFi channel - that's why it makes sense
If the wireless networks of the neighbors interfere with your WLAN reception, you should do something about it. Basically it is a factor on the way to fast Internet, but it is precisely this that should not be underestimated. Before we explain to you in detail why the WLAN in your home can suffer from too many other transmitters and what you can do about it, we recommend one of our PC-SPEZIALIST advice articles. In our article “Is your Internet too slow?” We have put together a lot of useful hints and tips that will hopefully give your home network the long-awaited speed boost.
Call up and evaluate the FRITZ! Box radio channel
To find out whether the WLAN channel is actually to blame for the snail's pace, first open the FRITZ! Box menu. There you can see under "WLAN" - "Radio Channel" - "WLAN Environment" which channels your router and the devices in the vicinity use to transmit. At this point, two problems are not uncommon, which we will now explain to you in detail.
Problem 1: Other routers use the same WLAN channel
Take a look at the diagram on the FRITZ! Box interface. The longer the bar, the more routers send on "your" radio channel. If you move the mouse pointer over this bar, you will also see the exact number of connected devices. Important at this point: Even if an extremely large number of devices use the same channel, they do not actually interfere with each other. But: They slow each other down. This is due to the fact that each channel or each radio link can only run one transmission at a time. If the data link is currently busy, the next one is put on hold. You may be familiar with a similar phenomenon when several family members surf the web at the same time via PC, laptop, tablet and mobile phone at home. As a rule of thumb, the more Internet devices transmit simultaneously on the same channel, the slower the data rate.
Pay attention not only to the WLAN channel, but also to the frequency range.
Problem 2: Routers transmit on adjacent radio channels
The second case sounds less dramatic at first, but in reality has an even more extreme effect on the Internet speed. Example: Your router transmits on channel 1, that of your neighbors on channel 2. So far, so good. The problem here is the frequency range - especially when it is 2.4 GHz. In this area everyone has WLAN channel times just a distance of 5 MHz to its neighbor. However, at least 20 MHz are required for (fast) data transmission. In the example shown, both routers use almost the same frequency range. However, since they are on different channels, they cannot “recognize” one another and therefore cannot coordinate with one another. The result: They transmit at the same time, which worsens both transmission rates.
Change WiFi channel - this is how you do it right
As you can see, when in doubt, it is not enough to just change the WLAN channel. You have to take into account the frequency range in the same way. Is yours Frequency range at 2.4 GHz, it is very important how many networks are in your area. For example, if there are only three, a friendly vote among neighbors is sufficient. Because channels 1, 6 and 11 do not overlap. However, if there are more than three other routers within your range, select the one from the three mentioned channels that does not send any other routers on adjacent channels, if possible. Next, the WLAN channel on which the fewest routers are transmitting. At a 5 GHz frequency range it is generally a little easier. Actually only the newer router models transmit here and the networks have more space between them. In other words: none of the 19 available radio channels overlap with any other. So here you just make sure that not too many others use "your" channel. But be careful: The 5 GHz frequency range harbors some stumbling blocks, such as radar stations that transmit in parallel. Your local PC SPECIALIST will be happy to explain the details to you.
