I am creating this thread because I need help choosing a new router for my home network.

First, let me give you a basic description of my home networking situation. Usually, my wife and I are the only two people in the house, and we each have a laptop, phone, and iPad. We also have a Chromecast which we use somewhat regularly, and I also have a home-built desktop which connects via Ethernet, so that's 8 devices total and 7 using wireless. My wife watches TV shows on Netflix regularly, so video streaming makes up the bulk of our network traffic. I also download games occasionally, but we don't download very many things otherwise, and the games I play are not online games. We are college students, so we can't afford the highest data rates from our ISP. I currently have a 15 Mbps plan with my ISP, and we are using a Motorola Surfboard cable modem and a Netgear N300 wireless router. The router drops its wireless signal and has to be rebooted at least once a day, and it is driving me insane.

The sole purpose of our home network is for Internet access. Neither of us has any need for transferring files between computers within our local network. I say this to emphasize that I have no need for gigabit transfer speed in a wireless router, LAN or otherwise. If I really do suddenly need to back up tons of data in my home network, one of my friends has already offered to give me a gigabit switch he doesn't use anymore. With that, unless I am significantly less informed about networking than I thought, I would be able to have gigabit speeds between computers in my local network since those connections wouldn't be going through the router.

I'm likely never going to achieve an Internet speed greater than 100Mbps, so I'm not concerned with routers that boast enormous speeds. 300Mbps is perfectly fine with me. What I'm a bit more concerned with is whether I should get a router with the 802.11ac standard. My current router is 802.11b/g/n, I think, and it only has the one 2.4 GHz band. I am highly tempted by the 5GHz band in many of the dual band routers I've seen, but what I can't seem to find out is whether I would benefit from them in any way. I have heard that the 5GHz band can have a much lower range, but my house is honestly pretty small. I just have a 2 bed 1 bath house, no more than 1000 square feet, and the router would be in the middle of the house. In fact, there is never more than one wall between the router and anywhere you can be in the house. I have been doing a lot of research, but I can't figure out a few things.

My desktop has an awesome wireless card that I know supports 802.11ac, but will the rest of our devices benefit in any way? I think the Chromecast supports 802.11ac, but I'm not sure about our Apple devices and Windows laptops. I honestly don't mind if the laptops don't get any benefit, because we don't use those for streaming video anyway. My desktop is the only device which downloads major files that aren't videos, and our mobile devices typically stream the videos.

Would the specific features of 802.11ac, such as the beamforming technology, be beneficial to us in any way? It sounds cool in theory, but I just don't understand it well enough to know if we would be able to use the higher bandwidth in the 80GHz and 160GHz channels with more than one or two devices.

From what I've gathered, 802.11ac is great for high quality video streaming. However, what I have not pinpointed is whether it is good for high quality video streaming only within a local network or if it is also good when streaming from the Internet. If the former is true, then I honestly don't think we need 802.11ac since we basically just watch Netflix. However, there also may be benefits of 802.11ac which would be relevant to my situation that I haven't considered, and that is part of the reason I have published this novel today.

Basically, I just want to know if I should spend the money to get a router with 802.11ac or if it would be pointless to do so based on my situation. I appreciate you if you took the time to read all of this, and I would be grateful if you would respond with your thoughts. I'll try to keep an eye on this, so if I haven't been clear on something, respond with any questions you have and I'll try to answer quickly. Thanks, everybody!

The coverage area is small, but you are talking about 8 devices, and streaming video. The price difference between an AC and an N router is not too much. The advantage, in your case is going to be that you will be able to send the video separately onto the 5 GHz band- if your devices support it. Even if they don't right now, as you replace stuff it most likely will down the road. The 5 GHz signal while it can carry more data has a smaller range but with the central location of your wifi, and the size of your residence this does not sound like much of an issue...
It depends if you are having issues. Almost all wireless routers can do faster than your internet connection.

Normally I would recommend INSSIDER so you could scan to see how congested the wireless near you is. Unfortunately they now charge for this tool unless you dig around and find the old version.

Still you can randomly try channels 1,6,11 and see if they work better or worse I suppose. The 2.4g generally has better coverage but there is more competition for the channels because most people do not have 5g/dual band equipment.

The 5g main advantage is there are more channels to choose from. Unfortunately because of 802.11ac we will soon have the same problem on 5g. There are really only 9 20mhz channels you can use on the 5g band. There are others but the router must detect weather radar and disable them and many manufactures have decided to just not even give you the option to use these channels rather than deal with detecting weather radar. What 802.11ac does it wants to use 80mhz which uses 4 channels. This means only 2 users can co exist and not interfere. When the new version of 802.11ac comes out later this year it will support the 160mhz option. This means a single users will eat all the available bandwidth on the 5g band. This is pretty much what is happening on the 2.4g band when people user the 150m option it uses 40mhz channels and there is only 60mhz total.

I suspect because of pricing it will soon be there is no reason not to buy 802.11ac since there will be very little difference in price. tplink sells their 802.11ac router for $99 already any it tests very close to the most expensive ones.

Pretty much there is no reason to not buy at least a dual band router. If you choose 300 or 450 or those other number does not make a huge difference because this is dependent on the ability to transmit overlapping signals..ie mimo. With all the interference already intentionally transmitting interfering signals does not work as good as it does in controlled settings. So going from 150 to 300 you might get 10-20% more throughput.

Although it is rare find them there are still dual band routers that transmit only on 2.4 OR 5. Most have 2 radios and can transmit on both they use the word simultaneous in the descriptions. Running both radios would give you the option to run some device on 2.4 and some on 5 which should reduce the contention between your device. It may not make much difference though if you are capped by a 15m internet circuit and do not do stuff like video streaming between devices inside your house.

I have the Asus RT-AC56U. Fast connections on both LANs, but streaming games and content on the 5GHz ac from the internet is horrible. (insane lag and buffering) When I switch over to the 2.4GHz LAN, everything runs like clockwork. In my opinion, AC and 5GHz is not ready for prime-time.

I bought a refurbished NETGEAR R6200 from amazon for 53$, a bargain considering its a 200$ router otherwise. Its speedy and has both bands. My 2.4 was dropping off and after I downloaded and installed various wifi analyzers on my android, I could see over 20 other routers on all frequencies, as I live in a neighborhood with apartments and condo's nearby. Granted they are far enough away that I could never connect, but they are close enough that they congest things. How much interference? I don't know. I know this: I never had problems until late last year when the apartments were completed, and they are about 200 yards away. SO: I got the 5g router and voila, no problems. This necessitated me buying a new wireless card for my laptop to pick up both bands, but it was cheap and easy to install. The biggest hassle was the drivers. I do notice that I can get upwards of 3mbps vs 1-2 earlier, and I dont know if I attribute that to "ac" or to the clear frequency of the 5g or both. Its not so much faster that it makes a dramatic difference, but its nice to see some benefit (besides the drop offs). They claim 3.0mbps on 2.4 and 8.6mbps on 5g, but rotsaruck with that one. I did get up to 3ish, for brief periods on 5g, but thats it. I didn't try 2.4 (for speed) with new router/card.

OOREMY--I think you might be experiencing driver issues. The driver issues are a nightmare with the lan card in the laptop. Most of the time they don't install properly, and require all kinds of finagling like deleting old, installing new, or not installing new, and copying over old, or whatever (not using auto installer). Once I FINALLY got my drivers straightened out, my 5g worked perfectly. Prior to that, it was unstable. That was my experience anyway. Hold the manufacturers feet to the fire re: drivers and this issue. If you look at the forums for the wireless cards, you see dozens of posts about this very issue, "5G is unstable" and the manufacturers response, "try this driver", "make sure you have the xyz driver", or "we are aware and working on", or more miscellaneous excuses/responses.

SCREEN764, I would also ask, "Do I want to buy a handful of high-speed 5gz adapters?"

Then I'd really need to ask, "Can my home-environment even support highest speeds on the 5gz bandwidth?" And despite all the studies and reviews, there's only one way to answer that - do it. Test it.

Monoprice sells a popular Broadcom-based ac1200 "kit" for $125 - a 4-antenna ac1200 router and its matched adapter. Additional adapters are in the sub-$40 range, and you'll find identical adapters elsewhere using various name-labels (including Rosewill).

But I might do a local-purchase of a high-dollar, high-performance dual-band AC product to determine if your home-environment will allow high-speed 5gz services. If not, then it's an easy "drive back and return product" exchange - no RMA hassle needed.

The other option would be an N router. I have personally used the Netis N300 router, and for $45 it is a serviceable solution that would serve your current needs- but just not allow for much growth down the road.
