Why does NVG510 give better speed wired than wireless in the same room?

If I connect my laptop to the nvg510 with CAT5, I get speedtest result of 7Mbps. If I connect wireless right next to the unit, speed drops to about 4Mbps.  Can you explain? Can I improve the wireless speed in some way?

Hi @wndavis !

 

Ensure that you're using channels 1,6, or 11 only on your gateway.

 

By the way, what device are you using to determine the speeds? Do you know what model wireless adapter is in the device? You might want to consider upgrading your wireless adapter.

 

Also, just for reference, the NVG510 is a wireless N 2 antenna device.

The short answer should be, yes.

your information was a little light, but here are some ideas off the top of my head.. If you are using a type g wi-fi router, upgrading to a type n increses both security and speed. (Idealy, a type ac, but not sure it's available from at&t routers yet.)

if there are any other devices, etc. that might be interfiering with the signal, moving or stopping them will help. moving the laptop closer to the router or moving the router closer to your laptop could help. a signal booster could help.

Not a clue how to do it, but using a differant broadcast channel for the wi-fi signal could help.

Just a few ideas to start.

One can also look up other threads using the search the community field above. for posts from folks way smarter than me, and can go into way deeper technical detail.

Hope this helps.

Sorry, that isn't any help.  If I'm stting right next to the WAP with my laptop, I don't think a signal booster is going to help.

I saw another post that suggested resetting the unit and I poked a paperclip in the hole with the red circle around it and no help, in fact, the wireless connection became slower yet.

Also, G modems are fast enough to support 7 Mbps. I doubt an N modem would help either.

During the course of the day, I was finally able to achieve the speed I was expecting throughout the house with my livewire devices and wifi connections.

By the time I was done, I had reset the NVG510 with a paperclip to the red circled hole in the back of the unit, and reset/synched all the livewire boxes (within two minutes) and rebooted my laptop a few times.  This is the first time I can remember using that reset button in the modem.

My Toshiba Satellite laptop is what I've been using to run speedtest.net on.  I finally have a speed of about 7Mbps on the laptop, wired or wireless and on my iPad Air as well as on my wifi connected Samsung Galaxy s3.  I'll have to remember this reset routine.

Thank you all for your posts that led me successful resolution.

Wired is always faster than wireless. Besides the slower medium (air versus a cable), I believe WiFi requires more encoding/decoding than wired does.

While it is true that the through put of the connection is limeted by the top speed of the modems connection to the internet, at only 6 mbps with the modem.. (i think that was what he said his connection spped was) the connection speed between the wireless device and the router should be faster..  not saying it will work any faster than the capacity of the modem, just, the radio signal between the router and the wifeles device is capable of faster connection speeds. Less lag, anyways.

 

But yeah, a hard wire connect does transfer data faster than wi-fi. Heck, the conector btween the device and the modem is WAY faster than the modems connection to the internet.

 

No real point other than trivia.
