Which is the best wireless router for a 3000 sqft house. I have a router in corner of the house because that is the only available connection, but cannot access internet in the other end or anywhere near the corners. Also, which is better? Wireless N or AC?
A 3000 sq ft house is not a very useful description. The solution if it is a square based building cam be quite different from a house is a a long slim building or even 'L' shaped. Having the router in the corner is also likely to be significant if the house is 'L' shaped or similar, depending upon which corner is involved.
The next factor is the type of walls, and specifically internal walls. Are they brick, stone or simple 'stud' walls with plaster board on a wooden frame?
The next question is whether it is single or multi-storey.
Extending the coverage of the WiFi network by splitting it into multiple networks in different parts of the house. Desktop computers, games consoles, TV boxes and Internet TV sets all tend to be fixed devices, so ideally they will use Ethernet connections. These may either be wired back to the router and may require an Ethernet switch to give extra connectivity. An alternative is to use Powerline network adapters such as:
to run wired networks over the houses power wiring. You can add extra adapters to these networks with only one adapter connected to the router. These adapters should all be fed from the same electricity meter, and should avoid surge suppressors and preferably not be plugged into extension power strips.
If you want WiFi around the house, then you can get adapters that include a wireless access point, such as:
Personally, although the separate WiFi sources can all use the same network name (SSID) and pass phrase, I prefer to use different network names to ensure that devices connect to a specific device and do not switch between devices.
Although AC (5 GHz) operation is faster than N operation (2.4 and 5 GHz), 2.4 GHz has greater range. Your choice of which bands and channels to use will depend on the local networks from your neighbours. Try and keep networks at least 4 channels away from other networks.
For slower WiFi devices, a WiFi Range Extender can be a reasonable solution for filling in corners that suffer from WiFi black spots.
I hope this helps.
First, one wireless access point is not likely able to reach the entire house; you are asking too much of wireless. Move it more centrally located and do not give me the excuse that it is the "only available connection". You probably need at least 3 wireless access points on separated channels so that you avoid co-channel interference. Wireless AC is the newer standard but sues such great bandwidth that you may find co-channel interference becomes a major problem. It is not hard to add wireless access points and this is what you need.
Eero Wi-Fi system is what you want. It involves multiple devices that you place strategically around your home. It will provide the best coverage.
AC is capable of achieving much higher throughput than N. Your results will vary depending on signal strength and the capabilities of your devices.
Not sure why I got thumbs down? You sound like you are not network savvy? Others have offered reasonable suggestions, however you would need some networking knowledge to make those work. Each has advantages and disadvantages. The Eero system is designed to make it easy, the assorted access points set up themselves. At $175 it won't cost you much more if any than buying the piece parts others have suggested.
BTW – I've worked in they networking business for the last 25 years. My home is wired with CAT5E to every room, my cable modem is in the basement, the router/access point is strategically placed as close to dead center of the structure as possible. I use a Netgear AC router, it supports both the 2.4Ghz band and the 5Ghz band. The coverage is excellent. My home is less than 3K feet though.
If you truly want a solid wifi connection in your house, your ONLY real option is to have the connection moved to the middle of the house. Wifi extenders will NOT provide decent speeds to anything connecting to the actual extender (it will be cut in half, and more depending on location of the extender, the router etc.
Once you have the connection moved, your existing router should work great.
Do you want a professional installation, give me floorplans and enough information.
Do it yourself? Run Class Cat-5 or better from the router to various places in the house, install Access Points to give you a strong WiFi signal.
Or you can get a crap installation, pitiful Internet connections, and use "adapters" and "repeaters."
Your current router, plus a powerline connection with a wifi adaptor on the far end.
Mesh router like the Eero. Those are more expensive than most but they do a better job.
TP Link or D Link
AC is better but i'd use more then one AP. try something like the Unifi AC and you can add as many as you need to cover the area
you may want to get a WiFi Extender, and position it halfway through the house.
