Satellite T110-10R with Realtek 8187se - connection drops on battery

Hi my friends,
There is a big problem with my laptop.
WLAN signal strength: very good
other laptops have these questions in this network.
Yes, here's my problem:
ca mode, there is no problem with the wireless connection, but on battery mode, my wlan keeps disconnecting connection, disconnection, connection... sometimes, this occurs several times in a single minute! It is quite painful and embarrassing.
This happens with different network wireless, tried different ones - not only my home network
my system:
Toshiba Satellite T110-10R with Realtek 8187se
Windows7 64 bit.
here a brief overview on the things I've tried
-Update BIOS!
-Update driver!
-Reinstalled operating system!
-power options: max performance
-even in all power options, I put a maximum performance for the settings of the wireless adapter, on batteries, too
-Properties of the wlan in Device Manager card, I disabled the option: allow the computer to turn off this device to save power
-in the same window, advanced, active 802.11 d

Well, despite the fact that I have this problem on my home network AND other networks, I tried following things on my router at home:
-updated firmware update
-reset the device
-no automatic IP (don't know the correct English term) - that I put on my laptop, too
-wlan changed to 802.11 b, g, b, and g, also tried wep
WLAN - channel set to auto and not auto, try different channels
-turned off all power saving features

... as you can see, I tried everything I KNOW...
Maybe, you guys have something for me that I didn't...

Well, hopefully, someone can help me with this problem...

> ca mode, there is no problem with the wireless connection, but on battery mode, my wlan keeps disconnecting connection, disconnection, linking

According to my experience, this has something to do with the old driver and power saving.
Depending on your message, this happens only in battery mode. So in my eyes, he pilots s/issue of energy saving

I found some interesting documents:
+ Wireless network card not working anymore after the change from AC to battery mode power +.
http://APS2.toshiba-tro.de/KB0/TSB12033K0001R01.htm

+ Wireless network connection disconnects when the AC adapter is removed. +
http://APS2.toshiba-tro.de/KB0/TSB12033H0001R01.htm

The second doc recommends updating the driver Realtek WLan may be, you can also try a page from Realtek.

  • Satellite M30 does not show the connection of the battery after 5 min of use

    Hello

    My Satellite M30 recognize the battery when placed first in and for 5-10 minutes.
    After that the power meter shows I'm on sector without battery. Any advice?

    Anyone know if it is an issue that could be fixed with a new battery, or if it might have something to do with the connection between the battery and the laptop?

    Thank you very much

    Hello

    If the AC adapter is plugged into the laptop that Toshiba Power saver should show a connected adapter. In this case the laptop must not run on battery!
    If you you unplug the adapter icon which appears in the taskbar should move from adapter to battery.

    One question; How old is your battery?
    Usually after several times the battery loses performance and it possible s you will be able to use the battery only for a few minutes. After this period, the battery is empty and needs to be recharged.

    Maybe your battery performance isn't the best right now and it should be replaced. ?:|
    This should be checked permanently.

  • Satellite U500 freezes with USB internet connection

    I have a portable Satellite U500 bought in Australia and I have a problem that when I connect to my mobile internet it freezes.

    I tried two different mobile internet providers thinking that maybe it's a problem with them, but both are the issue. I tried to put in different UBS ports (as there are three of them) and it freezes again any port. Via USB thumb drives in one of them or connection USB keyboard/mouse does not cause a problem, so I don't think that it can be USB ports.

    When I connect to internet via LAN to work I have no problem. I scanned my computer from viruses and its own. Frost occurs with mobile internet USB only and has only started in the last two or three months, I've had the laptop since December, running Vista.

    Help? Does anyone else have this problem?

    Which vendors you've tried?

  • Re: Satellite C650 - problem with the devices connected to USB ports

    Hello

    Can help someone, I have a C650 and everytime I try to connect to something to him via the USB ports, it is not "found" by the computer?

    The other night, I tried to get pictures on my phone but it wasn'; work and I put it down to a problem with the phone, but today I tried to install something digital crafts for my daughter and during installation it tells you to insert the thing into the USB port and click Next, when I do that he's going through a lot of "research" and said then it can not be found.

    The laptop makes a beep sound as it would on an extraction device when you plug... I hope that makes sense. So I am now assuming that the problem is with my computer, is there something I can do to fix this?
    Thanks in advance

    Sorry should add - it's like nothing is plugged at all when it is, and it happens on two USB ports, not just one...

    Hello

    What happens with plug n play like USB mouse device?
    You are able to use an external USB mouse correctly?

    > but today I tried to install something digital crafts for my daughter and during installation it tells you to insert the thing into the USB port and click Next, when I do that he's going through a lot of "research" and said then it can not be found.
    I guess this could be a problem with the software or drivers installed.

    I searched a bit and his city that he has a software is compatible with windows vista/2000/xp. Win 7 is not mentioned do not know if this could be a problem, but in your case, I recommend asking the support of this software product for some advice.

    In addition, you can try to install this software once more, check whether this USB problem appears again.

  • Satellite Pro L40 with realtek card: cannot see wlan Vista networks

    Hey

    You just bought the L40 (Realtek card) and it cannot see wireless networks. The diagnosis of Vista, is that the wireless adapter must be turned on. Then, it will fail to start. Function key and F8 (wireless on/off switch) does nothing.

    The wireless router is well - connected to an XP machine. I can connect to the router without a problem by using an ethernet cable.

    Running on the latest Microsoft drivers.

    Pointers much appreciated.

    Thank you
    Frank

    Hello

    you turned on the wireless the case switch on "ON"? Maybe you forgot this one, and this is perhaps the reason why it won´t work.

    Please check and make sure that you then use the FN + F8 switch.

    Would appreciate your comments on this...

  • Problem with my internet connection drop.

    I keep losing internet connection on my laptop Toshiba, he usually drops about 14:00 every day and I reconnect and on 5 minutes later, I lose again, I have two other laptops that do not have this, it's only this one and this one is new, I throw the bad shoots and he tells me that the default gateway is not available fixed. But then 5 minutes later it happens again. Can someone help me? I had this problem for months, I could use the help. Thank you.

    Hi Mike,.
    Thanks for the reply.

    Sorry I know this previous method suggested did not help.
    I suggest you to reset TCP/IP and check.
     
    Manually assign the IP address and the default gateway and check if it works very well. Before assigning the IP address and the default gateway manually, make a note of the IP address on the computer. To do this open command prompt, type ipconfig and press to enter. This displays the IP address, make a note of it.

    To manually assign the IP address and default gateway, follow these steps:

    a. in the system, right click on network icon tray. Choose the open network and sharing.
    b. right-click on the connection to the Local network and click Properties.
    c. double-click Protocol Internet Version 4 (TCP/IPv4) and assign the IP address manually.
    Example: Old Ip address is 192.168.0.1
    Replace the IP 192.168.0.50
    d. let the subnet mask and default gateway are the same.
    Subnet mask = 255.255.255.0
    Gateway by default, would usually 192.168.0.1 or 192.168.1.1
    e. click apply then click Ok and restart the computer and check if it helps to solve the problem.
     
    I hope this helps.
  • On Satellite L555-10R with Tempro and disc problems

    Hello

    Have what ASP you contacted in France?

    With regard to the Tempro.
    I recommend that you set the notebook back to factory settings by using the HARD drive recovery options (press F8-> fix my computer-> HDD recovery).

    End of the process after the retrieve, update Windows 7 to the last State.
    Download the most recent 3.33 Tempro, then try to install this new

    When I move away from it drops wireless.

    After having initially was very satisfied with its use, it now becomes more and more frustrating to use with wifi, with connections dropped and very slow performance.

    I have updated the BIOS and think I have updated all drivers wirelss, but could be the problem. It seems that wireless, software of management is at fault because the networks are detected, but not clinging.

    John

    > have updated the BIOS and think I have updated all drivers wirelss, but could be the problem.
    If you need to make sure that you use the latest WLan driver.
    The driver can be downloaded here:

    The laptop uses the Realtek RTL8191SE of WLan card.
    Please also reset the settings of the Wlan router. I had a lot of problems with my WLan and after the reset of the router, performance problems disappeared.

  • L755 satellite internet connection drops but stilll connected to the network

    Hello

    I hope one of you can help me. I have a laptop 13 q Satellite L755 nice for a year and a half.

    My problem is that I surf the net and suddenly my internet connection drops down. On Firefox or IE, I have a message with a triangular signal yellow saying: "your connection has be revived."
    I'm still waiting on my network but I can't access the internet.

    The strangness, is that my family other PC or laptop have no problem on the connection.
    This happens on the wifi and cable. At home or other places of connection.
    In France and the United States. So my conclusion is that there is a problem with my laptop.

    I looked around some forums. It seems that some have a problem with IPv6.
    I have disabled the option to use IPv6 on my laptop, but I still have the problem.

    Another comment: I play the Kingdom of the fortress online.
    Sometimes I disconnect from this game but I can still surf the internet for a few minutes before undergoing a total disconnection.

    Looking forward for your help.

    As this happens using WLan and LAN its really hard to say why your connection is interrupted.
    Have you tested the internet connection with fresh preinstalled system?
    I mean it is possible that some software / updates received or installed in the past it would affect.

  • Satellite L650/1MC - WiFi and LAN connection keep dropping out

    In the last two weeks, that my wifi connection dropped regularly - only a reboot solves the problem. Because it became so frequent (and boring) I returned with an ethernet cable, which worked OK for a few days, but tthat hen started making the same thing: no internet connection.

    I must emphasize that my other active wifi (android and android phone Tablet) kit continue to connect to internet via wifi etc, even when the connection of the laptop has fallen. This leads me to suspect that the problem is mobile partner no router etc. relates. The laptop is rarely used on battery, so I do not have the power as a problem management.

    I have a Satellite L650/1MC running W7 64-bit. I made no changes to my system recently which may give rise to this problem - everything works perfectly until a few weeks before.

    I checked for updated firmware updated on my router in the case where it is the question - it's not.

    Any suggestions to fix this annoying would be welcome!

    > I checked for updated firmware updated on my router in the case where it is the question - it's not.

    Have you tried to reboot the router?
    Since the two connections (LAN and WLan) stops falling, I think that the router is the problem.
    OK, two other android devices seems to work properly but the fact is that router shares automatically and possibly IP addresses, the IP address cannot be assigned correctly.

    However, you can check the WLan and LAN TCP/IP protocol settings.
    Uninstall the TCP/IP v6 and use only the v4 TCP/IP for LAN and WLan.

    Also ensure that your security programs (firewall & anti-virus software) don't affect the internet connection.

  • Satellite T110 - WLan connection has recently stopped working

    I have a Toshiba Satellite T110 with Windows 7 Home Premium.

    Wireless has recently stopped working with the yellow exclamation mark showing above the symbol of the unit.

    Looking at the pilot management screen, the following message appears.

    "This device does not work properly because Windows cannot load the drivers required for this device. (Code 31) »

    Nothing I have tried seems to shake this error.
    I tried the Toshiba assist diagnostic tool. It simply says that the wireless connection failed his test.

    I don't know how problem was that the system worked for about three weeks, without a hitch, but I would like to know if anyone has any experience with this problem.

    I could try a rebuild, but I prefer not to lose my OS.

    > "This device does not work properly because Windows cannot load the drivers required for this device. (Code 31) »

    I think that there is a simple solution; error message is clear enough; It is said that the driver cannot be loaded this means something has happened to the Wlan driver
    In my opinion you should visit the European driver of Toshiba page and should download and reinstall Wlan driver again!
