Does the laptop support wifi 5 GHz. Overview of modern wireless technologies
I have already written several articles in which I talked about choosing routers for different tasks, and from different price category. As I write this article, I will provide links to them. I also decided to write a relevant article and talk about choosing a router that supports the new 802.11ac standard. They are also dual-band routers that can operate simultaneously on two frequencies. Including at the new 5 GHz frequency. Many people are looking for the cheapest models of routers that support the 5 GHz network and the ac standard.
It is these budget routers that I will try to talk about in this article. Let's look at the most affordable routers that support the new standard, one model from each manufacturer. I think it will be fair. In any case, we will have a list of the cheapest router models that support the standard we need wireless network.
First, let's find out what 802.11ac and 5 GHz Wi-Fi are. If you're not in the know yet.
Router supporting ac standard and Wi-Fi 5 GHz. What is it and what are the advantages?
These are ordinary routers, supporting the new, modern 802.11ac standard. They began to appear on the market relatively recently, and are already actively selling. The prices for them were immediately very high, but since everything began to appear more models, competition appeared, and prices, of course, fell.
Now to the main thing. I already wrote, . This is a new, modern Wi-Fi standard. It only works at 5 GHz. Therefore, all routers that support the ac standard support the 5 GHz frequency. This is actually why they are dual-band. Since two can be distributed simultaneously Wi-Fi networks, at different frequencies: 2.4 GHz and 5 GHz.
You may ask, why do I need the old 2.4 GHz frequency? The fact is that not all devices (laptops, smartphones, tablets, Wi-Fi adapters etc.) can operate at 5 GHz and support the 802.11ac standard. Devices (Wi-Fi clients networks), which do not support the new standard, will connect to the network at a frequency of 2.4 GHz and operate in 802.11n (or lower) mode. I wrote about this in the article: .
If we talk about the advantages of the new ac standard, then this is, first of all, speed wireless wifi networks. It is higher than the previous 802.11n standard. Speeds from 430 Mbps to an impressive 6.77 Gbps. Nowadays, when you need more bandwidth to watch videos on high quality (especially on TVs), online games, downloads large files etc., a new Wi-Fi network standard, this one is like a sip fresh air. Since the 802.11n standard is already a little outdated, and it technical capabilities not always enough.
Another plus is that the 5 GHz Wi-Fi frequency is less congested. And this is the absence of all kinds of interference. And the absence of interference means more speed and stability. True, according to my observations, the level Wi-Fi signal networks from one router at a frequency of 5 GHz are slightly lower than at a frequency of 2.4 GHz. And there are also rumors that the new frequency does not penetrate walls well. But this most likely depends on specific model router.
Well, the fact that this is a new wireless network standard is, of course, a plus. Since in the near future you will simply have to choose a router that supports the new standard. In an article from, I advised in 2017 not to buy routers that do not support the ac standard.
Cheapest routers with 802.11ac (5 GHz Wi-Fi)
We will consider only the most affordable, budget router options, but which must have support for IEEE 802.11ac. Well, accordingly, they will be dual-band. Low price and the availability of a new Wi-Fi network standard are the main conditions.
In principle, you can do this without my advice. Just in some popular online store, set a filter by “IEEE 802.11ac” and sort by price “from cheap to expensive.” But I am already familiar with many router models, which I will write about below, and I have something to say about each of them. Polyus will provide links to pages with their reviews, feedback and setup instructions. If there are any on our website.
Important point: in different countries, and in different stores, prices and variety of goods, of course, differ. So please do not judge strictly if in your case some router turns out to be cheaper or more expensive. Or I won’t write about some model. You can always share your opinion and advice in the comments.
The list is just for reference. And so that you understand what you can focus on when choosing a router with ac.
Xiaomi Mini Wifi
And oddly enough, the most affordable router is from Chinese Xiaomi company. Xiaomi Mi WiFi model. In addition, this router has a USB port. Although, try to figure out how to use it for different tasks. All through some kind of application. A very stupid decision.
The router is good, but of course I won’t buy it :) Although no, I’m kidding, I already have it. I bought it not for personal use, but to see what kind of device it was. With such characteristics and at such a good price. Well, in order to write a couple of instructions for the site.
The router is interesting, beautiful, seems to work without problems (no experience with long-term use). But here is the control panel on Chinese a little annoying. You can install it, or install some firmware from Padavan, or PandoraBox. But these are unnecessary problems that not everyone will want to deal with.
If you need a simple and straightforward router that is easy to set up and understand different functions and you are not a fan of installation different firmware and other things, I do not recommend you routers from Xiaomi.
If you decide to buy this option, you will most likely find it useful.
There is more from this manufacturer Xiaomi model WiFi MiRouter 3. But it will be a little more expensive.
The router is generally good (especially for your money), and anyone can configure it. But you will need to understand the settings. The models are popular and there are many reviews.
TP-Link Archer C20i and TP-Link Archer C20
These are almost identical routers, only in different cases. I'm familiar with both models. I have TP-Link Archer C20i on at the moment. These are the most affordable routers from TP-Link that support the ac standard.
Both routers have a USB port. Good quality signal at a frequency of 5 GHz. Even the TP-Link Archer C20i, despite the fact that it has internal antennas. I will not talk in detail about these routers, since I have already done detailed reviews.
If you stop at these options, it will come in handy. And I wrote the same way.
Let me remind you that these are the cheapest options. TP-Link has a lot of routers that support the new wireless network standard. Closer to the budget ones there are also TP-LINK Archer C50 and TP-LINK Archer C25 models.
Netis WF2710
Another budget option for a modern router from Netis. I am not specifically familiar with the Netis WF2710 model. But I used routers from this manufacturer. I reviewed even cheaper options. True, they do not support ac.
I read the reviews, some are not very good. But this is probably normal, it’s like this with any router. Well, there is no USB port.
Judging by other models from Netis, I can say that the routers have a simple and understandable control panel in Russian. So there shouldn't be any problems with the setup.
Tenda AC6
Another option for an inexpensive, modern router. In terms of price, it will be slightly more expensive than models from TP-Link. And significantly more expensive for Xiaomi Mini Wifi. As far as I understand, the model is new, there are few reviews. It looks like this:
Of course there is support for the 802.11ac standard. Wireless speed up to 867 Mbps.
I’m also not familiar with this router, so I can’t say anything specific about it. See information on the Internet, read reviews from owners. It's just another available model router that suits our tasks.
Inexpensive ASUS routers with ac support
ASUS's cheapest models will cost more than the options we discussed above. The most accessible ones are Asus models RT-AC750 and Asus RT-AC51U. The RT-AC51U model is especially popular.
In the near future I will try to test these models and tell you more about them.
RT-AC750 and RT-AC51U are very good options budget router with support for 5GHz frequency. Pleased with the presence of USB ports and support for 3G modems.
Other models
- D-Link has interesting models: D-Link DIR-825/AC, D-Link DIR-806A.
- The manufacturer Totolink has a good model Totolink A1004.
- And Zyxel, as far as I understand, has the most cheap model (I have input with 802.11ac support) Keenetic Giga III. And it's not very cheap. You can take a look.
Let me remind you that we considered the most affordable options.
If your main goal is to save money when buying a router, and you are ready to give up new technology, then see my article with tips on choosing the cheapest router:
I hope my little tips will help you in choosing a router, and the transition to the new 802.11ac communication standard and the 5 GHz frequency will bring you only pleasure.

In the article we will analyze the advantages and disadvantages of Wi-Fi 5 GHz and 2.4 GHz, so that you can understand what kind of technology it is and what to choose. There are many standards and Wi-Fi technologies, whose names are usually taken from the letters of the Latin alphabet: a, b, g, n, ac. The first four are the most common and are found in most Android devices, and theoretical throughput can range from 11 to 450 Mbps. Whereas (ac) is just beginning to be implemented, but the speed can reach up to 1300 Mbit.
In practice, the download speed on the device can rarely exceed more than 25 Mbit, which is a consequence of the limitations of the router and the interference created by neighboring access points.
Advantages and disadvantages of 2.4 GHz Wi-Fi
Most home routers are inexpensive and use the most common frequency, 2.4 GHz (b, g, n). As a result, the network is very overloaded, because it has three separate channels, and when transmitting data, only one is used, which is also used by neighbors. In this frequency range a number of works household appliances like microwave oven or telephone, which may cause additional interference.
Because of this, delays occur in the transmission of packet data, especially over long distances and relatively high speed. At the same time, several key advantages can be identified:
Advantages and disadvantages of 5 GHz Wi-Fi
The 5 GHz (a, ac) frequency is almost never used for data transmission. The standard (a) is outdated, and (ac) is only now being introduced into new smartphones and tablets, so many users may simply not be aware of its capabilities, since this requires a router that supports given frequency. Fortunately, such routers are backward compatible, and due to two antennas, distribution can occur at a frequency of 2.4 GHz and 5 GHz.
The number of channels used in the 5 GHz range is 19, due to which data transmission increases significantly and the airwaves are much freer. As an example, the quantity available points access (left 5 GHz, right 2.4 GHz):
At the same time, despite the low network load and high throughput, there are several potential disadvantages. First of all, the coverage area is much smaller, so using Wi-Fi Internet connection in the far corner of the next room can be complicated. The second is foreign objects, which can create interference along the signal path, as a result, the signal passing through the wall is significantly weakened.
For a stable and uninterrupted network, especially if the device is in line of sight, it is better to use the 5 GHz frequency. If the distance to the router is too large and is accompanied by obstacles in the form of several walls, then 2.4 GHz. In the settings you can specify automatic change range and not think about manual switching. The only condition is to have an appropriate router, and the smartphone or tablet used must support the required frequency.

Rate it and support the project!
Against the background of total PR of the new 802.11ac (5 GHz) standard from router manufacturers, let's talk a little about it. So, if you listen to all the marketing hype, you get the impression that there are almost hundreds of bands in the 5GHz range and there is enough room for everyone. Is this true?
Let's start with the fact that in the 802.11 b/g/n standard for the 2.4 GHz frequency there are 3 non-overlapping channels. These are the channels:
- 1 (2412 MHz)
- 6 (2437 MHz)
- 11 (2462 MHz)
In this case, we are talking about channels with a width of 20 MHz. For 802.11n, 20/40 MHz channel width can be used. Large width channel provides greater speed. Those. if you start using 40 MHz width, the channel starts to overlap with 7 channels + 0.5 channels on each side.
And if there are a lot of such smart people, the airwaves become clogged, the points begin to interfere with each other, which leads to an increase in the Noise Level values (noise level) and a decrease in the SNR (signal-to-noise ratio). As a result - real speed falls. In North America, only 11 channels are used - from 1 to 11. In Europe and Asia, channels 12 and 13 are also available.
In the 5 GHz frequency range, 23 non-overlapping 20 MHz channels are available. Here you can already use not only a width of 20/40 MHz, but also a wide channel of 80 MHz (main + auxiliary).
First block of channels UNII-1 (Lower, lower)- frequency from 5180 to 5240, available non-overlapping channels of 20 MHz:
Second block UNII-2 (Middle, medium)- frequency from 5260 to 5320, available non-overlapping channels of 20 MHz:
Third block UNII-2 (Extended)- frequency from 5500 to 5700, available non-overlapping channels of 20 MHz:
Fourth block UNII-3- frequency from 5745 to 5805, available non-overlapping channels of 20 MHz:
There are 3 separate groups of channels:
- Japan(channels: 8, 12, 16; range 5040-5080)
- US Public Safety(channels: 184, 188, 192, 196; range 4920-4980)
- ISM(channel 165, frequency 5825)
The 802.11ac standard provides for the use of groups UNII-1, UNII-2 (both) and UNII-3, i.e. a total of 23 channels. Due to this, when using a channel width of 80 MHz, 5 non-overlapping channels are available. The same specification provides for the possibility of combining 2 channels of 80 MHz, which ultimately gives 160 MHz.
802.11ac - from theory to practice
And everything would be so rosy if the devices were more affordable and supported all 23 channels. Equipment entry level supports only 4 channels from the UNII-1 group. Met good equipment, which supports UNII-1 + UNII-2 + UNII-3. But I haven’t seen UNII-2 Extended at all. In the comments, you can unsubscribe whether you have equipment that supports the 802.11ac standard, and what channels it supports. I think it will be interesting and useful for many in the future.
An important detail: the range of 802.11ac is less (!).
