wireless speed slow, wired speed fast
« on: December 23, 2013, 12:31:05 AM »

Hi, I've got a 845L and the wired internet speed is around 95mbps according to speedtest.net. That's quite good for a 100mbps internet connection.
However, my wireless doesn't go higher than 34 mbps. When I'm connected windows shows a connection speed of 65mbps. I know I can't reach the 95 over wireless. But why I can't reach the 65? Even when I'm standing with my laptop next to the router, the speed doesn't go up...

Is this normal behavior or is there a way to make it work faster?

The settings of the router are the out-of-the-box-settings.

i've tried 2 laptops, 1 tablet and 1 phone.

Results:
1 laptop 34mbps
1 laptop 42mbps
tablet: 24mbps
phone (galaxy s2) 18mbps

I've put the router in the livingroom in the middle of the room on the table to test for better results, but no difference.

it also depend on the wireless of the Laptop. Older laptop only have slow WiFi.
If you have new chipset which support faster connection it will be faster.
I try 2 different N device and the result also different.
G is lower

I know, but why i only get 34 when i'm connected at 65? My internet speed wired is 100, so it should be around 60 mbps imo. So why that drop of 31 mbps?

Link>Welcome!

  • What Hardware version is your router? Look at sticker under router.
  • Link>What Firmware version is currently loaded? Found on the routers web page under status.
  • What region are you located?

Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?
  • What ISP Modem service link speeds UP and Down do you have?
  • Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
  • For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy
  • Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
  • What wireless modes are you using?
  • 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N on 5Ghz?
  • Channel Width set for Auto 20/40Mhz or try 20Mhz only.
  • Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
  • What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
  • What wireless devices do you have connected?
  • Any cordless house phones?
  • Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
  • If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.

It's not recommended to speedtest over wireless connections. There are many variables that can impact and cause inaccurate wireless speed test results. I recommend alway speed testing wired LAN connections first to ensure you are getting your ISP paid UP and Down speeds.

Connections on WiFi should be to what the Mfr if the device supports. Various devices have different connection speeds. This is different from actual data xfer speeds. You'll need to refer to the devices Mfr support site to find out what devices support for wireless connection speed between the device and the router.

I've tried everything, all the different combinations of security and bands, N mode only, G mode only and so on. Still max 65mbits connection speed (34mbit internet speed).

As I said before, my ISP up and down speed is 100mbit (fiber).

I think I bring it back to the store. At least I should get 50mbit. Because that is what I get from a 50mbit connection at my parents home (with a different cheap old wifi router...)

Some devices depending on how they are designed, may not be able to support those kinds of speeds over Wifi. Only wired LAN devices can support those speeds. As long as your wired PCs are seeing those speeds, the Wireless will be working as designed on these routers. If your getting 65Mbit speeds on your wireless devices, your probably hitting a limit on the wireless devices, which this is not a router issue.

Suggested performance wireless settings would be Single mode N, WPA2/AES only, Auto 20/40Mhz, HT20/40Mhz Co-existence OFF on 2.4Ghz. Mixed AC and N mode, WPA2/AES only, Auto 20/40/80Mhz on 5Ghz.
