File Transfer Speeds


For our router file performance testing, I use a SanDisk Extreme Pro 128GB Flash Drive formatted in the FAT32 or NTFS filesystems. I then use NAS Tester 1.7 with a 100 and 1000 MB file size and loop it five times with an average result being charted.




Starting out with file testing, the ACS provided 74 MB/s read for the 100M file and 95 MB/s for the 1000M file size. After switching over to write performance, I noted the 82 MB/s 100M performance followed up by 108 MB/s 1000M file performance.



Final Thoughts


The Linksys WRT1900ACS has me just as excited as the original. The build quality is still there although this router does seem to have much nicer plastics this time around and of course, it still carries a bit of weight, thanks to the heat sinks. It has also been nearly two years since the initial launch of the WRT, so Linksys has had time to iron out a lot of firmware issues, including the file performance.



Speaking of performance, this router brought in average results on the 2.4GHz band but really excelled once I started testing the 5GHz. Going by my charts, the ACS topped all previous AC1900 solutions at 484 Mbps on the 80MHz band, which is certainly a feat. Range too was quite good with the WRT, as not every router I have tested in the past has been able to hold a connection all the way to the garage. With that said, it did get down to 54%, which can be a bit iffy at times. On the plus side, the file performance of this router is just astounding - I'm talking NAS level file performance from a router!


In closing, if you are one that wants complete control of your router wherever you are, the new Smart Wi-Fi app is multitudes better than the previous solution, and the Smart Wi-Fi platform as a whole has been vetted over several years now and appears to have all issues worked out. Simply put, if you want the hands down best AC1900 router on the market, it's the Linksys WRT1900ACS.
