Hey guys, So first of all my apologies for delaying the review by a week due to some unforeseen circumstances. But it has given me more time to test the router even further more.
I currently have an 8Mbps connection which goes up to 10 at night. I have also updated the router's firmware to the latest version before testing it out and tested both bands using laptop and mobile.
I will start off with 2.4 GHz first. The range is excellent!!. When compared to my previous router Asus RT N13U, The Asus AC58U gives about 40% better range. I have tested it during heavy load and normal usage, and i have had no trouble with connecting to wifi although as expected speed does drop during heavy usage. Since the last 2 weeks of continuos usage, I did not encounter any signal drop or disconnection issue (Router is on for 24 hours). The only downside i see here is that if you make any changes in the router, the router takes some time to reboot and implement the changes but less time compared to my older Asus router.
To give a hint on the range capability, I have connected the router from the ground floor of my house while i stay in third floor. If placed right, It should easily cover an area of 800-900 sq. ft.
The 5 GHz range is the only downside in this. It is not the same as 2.4 GHz. I suspect its the new firmware which is causing this as the previous firmware had higher coverage area. Although it is stable and encountered no drops in speed or range or disconnection.
Getting to the firmware, When i installed it the first time, i was using the stock firmware which came with the box. I used it without updating for 4 days to see the difference when i upgrade it to the latest firmware. The previous firmware had issues especially with the 2.4 GHz line. There were some unexplained drops in speed but 5GHz worked well without any trouble. Post the update, the 2.4 GHz is working flawlessly. They seem to have fixed the bugs of 2.4 GHz. Hoping for a similar fix in range for 5 soon. My current firmware is 3.0.0.4.380_7485.
Please note that on a given date, we have 4 mobile phones and 2 laptops connected at all time along with the pc.
Thanks to
