Far more than just eliminate dead spots

This is primarily a Dual Band Gigabit Wireless Router without DSL modem or any VOIP features.
Thus, the device is in most applications, as a complement to existing DSL modem / router that establishes the Internet.

The typical use such a setup is to extend the home network and here mostly to improve the WiFi coverage - and this may be the WRT 1900AC really perfect.
I have connected the device to a Fritzbox 3490 and had more than one floor plus staircase plus living room still good reception on the porch - but only in the 2.4GHz band.
But never mind - what matters is that this is not achievable with the Fritz box.

If in addition to WiFi even wired network devices are supplied, is the Linksys 4 additional Gigabit ports.

As the name suggests, is next to N600 also supports AC1300 - here is to pay attention to the proper encryption. In addition to the other standard features also following specialties can be highlighted:
- USB 3.0 connection
- ESATA connection !!!
- The ability to create different VLANs (networkers will be pleased)
- 802.1x based authentication via Radius Hardware

The 4 swiveling antennas are outside screwed and can if necessary be easily replaced by commercially available directional antennas - also in newer Fritz boxes no longer possible without modding.

The two weak points of the device are
- The power consumption of approximately 25W
- The price

For Linux enthusiasts certainly worth mentioning the device supports Open WRT firmware.
A first glance at the menu reveals however fast that here already a whole lot of effort put in it.
So I would pull itself once no firmware mod into consideration.

One last notable gimmick is the option of downloading a smartphone app, with which the router can be managed anytime, anywhere (with coverage).
Of course, is always a security question if you want to activate a feature.

In the end I will not deny that I have had to take the good device against a vile TP_Link N600, who was previously in charge of the WiFi coverage with me.
What can I say - the TP_Link was not significantly worse in WiFi range.

Therefore, the decision for the Linksys is always a question of the other features that does not have a TP_Link precisely.
In firmware, interfaces and latest standards are worlds between the two devices, but also the price.

Who wants to use the unit may equal as NAS and want to bring or test the latest network technologies are used gold with the Linksys. Since then you have not even provide the most expensive than DSL modem Fritzbox because of the professional features you are definitely better served with the Linksys.
