Satellite L755D-120: slow down the speed of 20mbps WLan

Hello

I have an internet connection of 70mbps/10Mbps and when my laptop is connected to the router with a wire, I have this internet speed.

But when I use the WIFI connection on my Toshiba Satellite L755D-120, I get only a speed of approximately 20 MB/s down. My router is a DLink DIR-615 router and my laptop is compatible with the 11n networks.

However, I have a USB adapter, which is not supported by 11n, but when I use that even to get a speed greater than without it--about 27 Mbit/s. How can it be possible?

I was wondering about the possibility that the laptop isn't suppert 11n, even if the specifications of the product tell you?

Thank you.

The laptop seems to bear the 802.11(b/g/n) Atheros AR9285 WiFi card.
So, you can use the standard 802.11 b, G or N.

Are you sure that the Wlan card is set to N?
You can check in the Device Manager-> card WLan-> properties-> Advanced tab

By the way: the 802.11 standard would operate the frequency of 2,4 Ghz because that 5 GHz is not allowed for an 802.11 wireless network cards support and therefore slower.

  • Satellite L850 - error of cooling and slow down the speed of the CPU even when fan to 80 c

    So, I have this problem that my fan stops turning when the system is under load and then turns on, starts running at the speed of 100%, an error which says error with cooling system, laptop computer back to the service.

    The fan slows even when the laptop cools completely, it only returns to normal speeds once I closed the laptop.

    In the last few days, which has stopped completely. Now the fan won't even middle speeds even though the CPU temperature is 80 C. Due to the bad news of cooling time score about 70 ° C, even at idle.

    The laptop is almost a year. I already had this problem after a week of buying it, and they replaced my processor. I have windows 7 x 64, amd 7670 m and 2350 m i3.

    I wonder if this may be a BIOS problem or I have to take for the service? How can I stop this from happening? And Yes, my power plan is on high performance.

    AFAIK the cooling fan is controlled automatically if you don t have a any influence on it. Temperature sensors are placed on the motherboard and they control the cooling fan activity. That one possibility to change fan cooling activity is to change the option in the option of cooling method (advanced power settings > Toshiba saving settings).

    In my opinion the best solution for you is to contact the nearest Toshiba service provider and ask for help.
    They have diagnostic tools that you can check all this.

  • WRT320N slows down the speed of connection - terms of support of Linksys problem

    My internet connection speed slows down to about half of it is normal speed (or worse) until I have restart my router WRT320N. I see on the net that MANY other people have the same problem and can't seem to find a solution to this problem.

    I have the latest version of the firmware installed and I have the upnp is off

    I was told recently by a representative of Linksys Chat to perform this procedure, and I was wondering if anyone has tried and there set the coupling apparently daily slowdown that set in a reboot of the router for another day or two

    Here is the procedure that I was instructed to do...
    I was told disconnest the modem to the router-connect "than a PC ONLY" via a wired port #4 - reset the router by holding the button of reset in 30 seconds - switch off the router Linksys for 20 seconds and then turn it back on - check the LEDs of the Linksys router to make sure that the power, WLAN and port #4 are lit on the Linksys router. -clone the MAC - change "Mixed" wireless settings - name - change to 20 Mhz channel bandwidth and network use standard channel 11 - and in - use the Mode personal WPA - security settings and set my WPA pre-shared key password
    Before shutting down the PC and router - reconnect the modem to the router and the PC to the router - then make sure that the modem, the router and the PC are disabled for cycle a minute and the power of their back on with the modem being first - then turn on the router and last the PC

    Has anyone tried this, and he had to fix this downturn?

    Thanks in advance

    Well it's been 6 days that I woke up this morning and turned on the router and the modem from power overnight or lower I did after question troubleshooting the slow speed in the night before, does not

    I consistantly get in the 2 to 3% of the broadband speed I pay for - but I have no idea what fixed the issue

    So I'll mark it as "Resolved" and just hope that it comes not back again

    Thanks for the recommendations Klatch

  • Slow down the speed of the Internet with TC Gen 5 and Time Warner Modem

    I use the 3 TB Gen 5 Time Capsule and Time Warner Cable Modem. Recently, TWC has increased the speed of internet download at 300 Mbps. using TWC speed Test I get about 95 not only when you're using TWC Wi - Fi, but also when my iMac is directly connected to the TC by ethernet. I get almost 300 Mbps when TWC Modem is connected directly to the iMac by ethernet. I'm surprised that the speed of WI - Fi is nearly one-third, but more surprised than speed is also a third when connected by ethernet. I don't understand how the TC and TWC modem work together. My use of TWC rather that TC Wi - Fi Modem Wi - Fi has been recommended by Apple Support when they helped put in place the TC about six months ago. I don't know what I should be waiting. TWC has replaced the cable Modem so that is not the culprit. TWC also said speed of 300 the Modem must be connected directly to ethernet to the computer. There may be a configuration problem or a lack of understanding on my part. To unravel it any help would be appreciated.

    Fixed: using the TWC speed Test I get about 95 not only during use of the TC Wi - Fi, but when my iMac is directly connected to the TC by ethernet.

    You can install CPUID HWMonitor (there is a free version). Then monitor your time in various conditions.

    Lasvegaswireman said, quote "you can't change the speed of the processor and chassis/case on your computer fans.  I would at least look at your BIOS version 7, that you have installed. There may be the thermal fan settings. See here under the Power Tab, thermal Menu menu

    The thermal menu displays the following items:

  • Satellite A665-14N - slow down the download and upload

    Hello, I have a Satellite A665-14N only 1 month. The problem is my upload and download speed, only 0.5 mp/s, upload on 0.08 lower load. Have the last driver for broadcom 802.11n wifi Date 21.01.2010. NSV. 5.60.48.35 but nothing done.
    I use a D - link WIFI WRT150n router

    Y at - there someone who can help me?

    Hey,.

    Have you already checked the download speed and upload using another computer or laptop?

    I'm not sure, but I could imagine the problem is caused by the functionality of your energy saving wireless network card. You can change this in Windows power management. I recommend you to disable the saving of the WLAN card to improve performance.
    Here is a guide that is interesting how to manage power management features:
