Big home

I live by an big old house with a couple concrete walls so my curent router is not enought. Since I'm buing a new laptop with AC I might as well buy a router also.
My laptop will have one of this adapters:

• Intel® Dual Band AC 7265 [M.2 Chip] 802.11 A/AC/B/G/N 2.4/5.0GHz + Bluetooth™ 4.0 (SKU - WIFIX1)
• Bigfoot Networks Killer™ Dual Band Wireless-AC N1525 [M.2 Chip] - 802.11 AC/A/B/G/N Wireless LAN Module + Bluetooth 4.0 | (2x2)

I'm looking for a afordable solution to wifi my home, should I use a repeater for that? (distances of 120ft separated by 2 glass panels and distances of 35ft separated by 2 concrete walls)

• NETGEAR Nighthawk AC1900 Dual Band Wi-Fi Gigabit Router (R7000) + same brand repeater
• TRENDNET TEW-818DRU AC1900 Dual Band Wireless Router + same brand repeater

Thank you very much!

 

I'd go with a Netgear (for reasons explained in a sticky) and Killer card (in spite of its price).
As for the repeater - postpone the purchase. First see how the router performs - then (if needed) buy a repeater. You may not need one but you also may need more than one (which may make you buy cheaper ones to avoid driving the cost up)

Killer card is overpriced but it's a good way of avoiding Intel 7260/7265 which all things considered is troublesome.

 

The Killer N1525 Wireless-AC works very well in an MSI GS60 notebook paired with a Netgear R7000 router at distances between 20 and 30 feet(7 to 10 meters) from the router going through 2 and 3 sheet rock walls.

I also own an Intel AC-7265NGW that I tried in the MSI GS60 notebook over the course of 10 days.

Downloading different types of files from various Internet sites exposed little if any difference between the 2 wireless cards.

The Killer N1525 shows a constant 866.7 Mbps Link speed while the Intel AC-7265NGW fluctuates mostly between 702 Mbps and 866.7 Mbps with occasional drops to 526 Mbps.

Transferirng files across my home network had the Intel AC-7265NGW average between 38 and 45 MB/s and the Killer N1525 averaged between 55 and 62 MB/s

So if the notebook you're thinking has the N1525 then I would suggest you opt for it and pair it with a Netgear R7000.

I have no 1st hand experience with range extenders.

In my previous home I had 2 steel reinforced cement walls between the R7000 router and an MSI notebook with an older Intel AC-7260 mini pcie wireless card.The theoretical link speed reported by Windows 8.1 WiFi Status Monitor fluctuated between.526 Mbps and 702 Mbps from the non line of sight location 21 feet(7 meters) from the R7000 router.

I use the Netgear R7000 stock firmware issued by Netgear.

EDIT:
If you don't need a new notebook quickly I suggest waiting till Mid 2015 for the Intel Skylark platform to be released.

Just like Sandy Bridge was a huge advancement over the previous generation Skylark should be huge over what is now being offered.
