Thick brick internal walls (between rooms, not exterior walls)?
What is 'lots of iPhone, gaming consoles, Macs, PC's, ipads' etc.? Specifically (a single number)?
What the RT-AC88U can offer (eventually, when you have the required clients that support MU-MIMO in the immediate or near future) is the ability to continue being useful for your networking requirements (wired and wireless) by giving you better overall network performance as time goes by. While the RT-AC68U in the same situation may prove to be overwhelmed (depending on the above answers to my questions).
You have indicated previously that budget wise, you are able to get the higher end model. I have never seen a downside to doing so (if it works for you initially, in your network environment, it will continue to give similar (great) results). Depending on the actual number of clients, an RT-AC5300 may also be worth considering too (because you'll be able to put slower/older clients to one of three radios and your faster or more demanding clients to the remaining two radios).
Thank you very much for your reply!
Ok, so here are the infos you asked for:
1. Its a very old house from the 1950´s, and it was constructed using very thick bricks laying down (as opossed to standing up) and lots of sand with cement-like material to cover the walls, so they are thick, like at least 20cm, between rooms, and extra-thick exterior walls (30~40cm) around the house.
2. Well, lets see....
02 iPhones
02 Windows smartphones
02 Windows laptops
02 Windows desktops
01 MacBook
01 iMac (sometimes wired, sometimes wireless)
04 consoles (PS4/PS3/Xbox One/Xbox 360)
04 iPads (02 minis/02 iPad 4)
01 Smart TV
01 Apple TV
USAGE : extreme daily use of 02 Spotify clientes, intense daily use of Netflix and YouTube (both on TV and iPads) and very frequent use of online gaming on consoles, somewhat frequent torrent downloads on one desktop/laptop.
When I move to this new 2 floor house, you can probably add:
01 smart TV
01 laptop
maybe another Apple TV
surely another PS4 or a Xbox One (both with some time)
3. Well, off course money is an issue, but since its a very complicated process to purchase an equipment like these in my country, and I can only do it once every few years, I have to make every cent count, so I MUST choose an equipment thats not just very good, but that also "exceeds" my current needs a little bit, so it will last longer and still be a good choice in two or three years time.
Do you understand my point?
Im
NOT in USA or Europe, and I
can´t just walk into a store and ask for a refund I´m not satisfied with a certain piece of equipment.
I consider these purchases as
investments, so I look for the best current equipment, that will still be very good in a couple of years.
AC68U was THE BEST/top equipment one year ago, and it an excellent equipment today, but it wont be such an excellent equipment in 2018, and it probaly wont be adeequate for my network by that time.
Almost 10 years ago I purchased a very expensive router made by Linksys, the WRT54GL, if I remember it well. I was VERY expensive for me, but it had amazing online reviews and when it arrived, it was a huge improvement for my home network. It served me very well for at least 3 or 4 more years. Had I purchaased a cheap D-Link at that time, I probably would have to replace it in a year or so...
That said, if you assure me that given my currrent equipment list (that surely will grow over time!), a RT5300 or a AC88U will definitely provide a more powerfull signal performance/coverage than the AC68U, covering far corners of the housewont AC68U wont be able, I´ll definitely get one of these, even if I dont need 80% of the features they have.
Poor and slow WiFi signal is better than no signal at all.
My biggest concern are the tests I have seen on various reviews (including on SNB) stating that at 2,4Ghz, over 30feet tests, both AC88U and RT5300 have
inferior performance compared to AC68U.
