Title: Slow transfer speeds on wifi lan between phone and pc.
Post by: joncenawordlife on July 15, 2015, 02:24:17 PM

Guys I have a DIR-600L router.
Current Firmware Version  :2.04

Everything works perfectly on my computer, internet is wired from my isp and so obviously my DIR-600L.

The only device I use wirelessly is my Sony xperia Z3 phone.

I access my computer from phone wirelessly to transfer data to free up phones memory.

---Now the real problem begins here....
I dont get transfer speeds more than 4.25mbps on my phone while I transfer data from phone to my pc.
Doesnt matter even if my pc is idle i.e. no internet activity etc.

---Steps I tried:
In router settings, tried Channel 13 but no use.
Computers lan card (Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC) is manually set to 100mbps lan speed.
My isp speed is 50mbps.

There arent more than 2 wireless routers of other people in my neighborhood and both of them use channel 1 and 4.
Also when I do such data transfer I sit in the same room as my computer and router. So no question of any interference.

I know 4mbps is just too slow and I should get more than that.

So please help me get more speed wirelessly for my phone data transfer.

• Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channels) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
• Ensure any devices with WiFi adapter drivers are updated.
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
• If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.

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.

Refer to the devices Mfr support site and information on connection rates and speeds the devise supports. Not all devices support fast xfer speeds which differ from connection rates.

Try Mixed G and B.
Disable 20/40Mhz Coexistance and Short GI
Disable WPS
