Title: DIR-895L - SLOW Wireless Speeds - extremely slow
Post by: rbc1975 on August 02, 2018, 06:41:40 PM
Hi All. I am hoping that someone can help me out. I have had the AC5300 for about 18months now, and was very happy with it when i first bought it - great range, great speeds.

However over past 6 months or so, I have noticed a decline in internet speeds. I have tolerated it thinking it was probably my ISP, or simply many devices streaming over internet.

So ... I have been home on my own for past 2 days and have found that the internet is equally as poor when no one is using it. So I decided to bite the bullet and investigate.

I have isolated the router and changed SSID so there is only one device on the wifi and internet connection at the time of my testing. I have turned off 'smartlink' on the router so i could manage 2.4/5GHz channels separately. I turned off other wifi devices in my immediate vicinity that may be getting in the way (Google Home, Chromecast, Speaker System, etc)

Here is what I have found in regards to Speedtest.net results

Attached to ethernet of ac5300   - 118Mbps / 10Mbps - very happy with this result

at 0.5 metres from router
     2.4 GHZ      - 25Mbps / 4Mbps
     5 GHZ         - 40Mbps / 6Mbps

at 3 metres from router
     2.4 GHZ      - 10Mbps / 2Mbps
     5 GHZ         - 18Mbps / 3Mbps

and the results only go backwards from there.

When I first purchased the router I was getting 100Mbps / 8Mbps from pretty mush anywhere in my house and yard. Now, 18mths later, I am getting no where near this, and with 4 adults and 2 teenagers in the house, the router is proving to be a major bottleneck when everyone is home.

I have changed Wifi Channels, Channel Bandwidth, 802.11 Modes, Power across all 3 channels within the Wireless config - each to no benefit. I have reseated all the 8 antennas on the device. I have applied firmware updates with factory resets before and after firmware upgrades / downgrades. No matter what I do, I am getting no result.

Is there something that I may be missing??? Is it likely I have faulty device? Bad Firmware?

Many thanks in advance

What wireless devices are you testing with?
Same speeds with other wifi devices?

How is the router placed?
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
