Hello!

I have a Toshiba Satellite C655D laptop connected to my home wireless network (802.11n). I can get downloads speeds of only about 1.5 Mbps, with upload speeds of about 3.5Mbps. Here is a recent speed test through Xifinity (Comcast), my internet provider: http://stage.results.speedtest.comcast.net/result/121092262.png

I have another laptop connected to this same wireless network that gets about 17 Mbps download and 3.5 Mbps upload. Therefore, I think I am being limited by the wireless adapter inside this Toshiba laptop. Device Manager identifies this adapater as a Realtec RTL8188CE Wireless LAN 802.11n PCI-E NIC. Device Manager says I have the current driver installed for the adapter.

Do you have any ideas that could speed up my connection? Thanks for your help!!

I would go here to the download link and see if they show any issues with the wireless and also look for a updated driver for it. Only use the Toshiba supplied drivers for best results.

I didn't find any update info about the wireless card on the Toshiba site. It had the same version of the driver - I installed it, just in case there was a problem with my copy of the driver. No change in download speeds. I then joined the Toshiba website to view their forums on the issue. One posting suggested contacting the Realtek website for the latest version of the driver - which I did and installed. Even with the new version of the driver, the download speeds are the same.

I called customer supprt for Toshiba and they were not able to help me. They are suggesting a full back up and then doing a system recovery. AFter that, they suggest sending in the machine for warranty service. Do you have any suggestions before I send it to them?

Thanks for the help!!

Is it still under warranty? If so see if a local Toshiba service center can do the warranty on it.
This web site should let you look up warranty status.

Either way I would backup the hard drive.
Make the recovery DVD set if not done already, just in case.

I would also do a test of speeds with a wired connection to be sure it is a hardware rather than a software issue.

It is still in warranty, so I think that is the route I am going to have to go. I was hoping for a simple fix that wouldn't take the laptop out of use for a while - but oh well. I did try the speed test with a wired connection - it was about 25 Mbps - so it is the hardware. Now I just need to back up my machine and get it repaired.

Thanks for the suggestions - I appreciate that you took the time to answer me!!

THANKS!!

I had the same problem with my new Toshiba Satellite. I did EVERYTHING I could think of or read in forums to try to fix it, and nothing worked. Like you, I assumed it wasn't the adapter, because wired or wireless made no difference, however, in my case it WAS the adapter. I already had an inexpensive little USB adapter, (part of a workaround on that old dog VISTA) so in a last ditch effort, I went in and disabled the network adapter and popped in the usb adapter. My download speed prior to doing this was around 3mbps. As soon as I went to the USB adapter, my download speed jumped to 45mbps, which for a wireless connection through a concrete wall is respectable. I suspect that some of the Satellite models have a defective built-in wifi chip and sometimes ethernet chip too. Crappy quality control, but the problem was fixed for ten bucks which was cheaper than shipping it back and less hassle than doing a factory reset (which wouldn't have fixed the problem anyway)  The little Edimax USB wireless adapter runs about $10 on Amazon and it fixed my problem.

Hi Rosemary

 

have You checked to see if there are any Toshiba Authorized Service Providers near You? If they determine that the Wireless is bad they can change the the motherboard at their location. Toshiba Overnights warranty parts.

 

Not to mention that Toshiba will send a prepaid return carton for warranty work. IMO having to have a USB adapter sticking out that can easily be damaged or cause damage to the USB port is not a good thing.

 

Good Luck

Roger
