NETWORK DISCONNECTS RANDOMLY, I READ EVERYTHING HERE AND NOTHING WORKS, PLEASE HELP ME! :(
Lenovo G510
Intel core i5 - 4210M
Windows 7 ultimate
Broadcom 802.11n network adapter
For almost a month I had problems with my laptop because it disconnects randomly the system for some reason, I can't identify.
It can operate correctly for one hour, then disconnects the wireless network card. Every now and then, or every 10 minutes, depends on the day I guess.
I had a lot of reading the forums on this topic and found nothing to work up to now
That's what I tried:
-everything is on maximum performance
decliques-i 'allow the computer to turn off this device to save power ".
-disabled some 'ip helper' in services
-check all that relates to the router (change channels, interference with other routers or wifi), the hardware part SEEMS very well (the laptop is fairly new, it's like a year and never had any problems with it)
-verification of updates of drivers, it says I have the latest version
-fully scanned the laptop for viruses and none has been detected
n ' install any programs lately that could cause this
-network, signall is excellent
And still nothing worked. NOTHING. I'm really desperate now. The only thing that makes the network working again almost instantly (like5-10 sec then that if I let him restart itself it takes 2 minutes for even 30-40 minutes), turn and turn again on the wireless network card (I have it by pressing the airplane mode)
If no help pleaseeee? I noticed that it happens to many other users also.
If the steps we have provided above has not resolved the problem with intermittent wireless connectivity, then what Canadian technology said, it is likely that the problem lies in the material.
Intermittent wireless connectivity are often caused by loose or defective air intakes to the wireless card, or a faulty card as well. This is the reason why Canadian Tech informed on the use of an external USB wireless device.
Another option is to contact the manufacturer of your device, which is Lenovo, for repair options based on security they provide. You can contact them via this link.

How to change the size of taskbar buttons? I did everything that I've seen proposed in these pages, and nothing works.
The buttons of programs open in the taskbar are tiny and square. I want them to be of normal size (by default). I have locked and unlocked the task bar. I moved the "three vertical lines composed small points." Nothing works.
If you want to enlarge all the icons in the taskbar, and then increase the point size of buttons of legend to a larger number of advanced appearance settings.
Follow these steps:1. click on start, Control Panel, personalization, window color and appearance.
2. on the window color and appearance, click "Classic appearance open for more color options" (link below).
3. in the box "Appearance settings", click on the button "Advanced".
4. in the box "Advanced appearance" under "Item:" dropdown, choose "buttons".
5 set your size
6. click on the OK button.
7 on the "Appearance settings" box, click on the button 'Aplly', wait.
8. click the OK button if you are uncomfortable with the size to change, or just click on the "Advanced" button to set the size.I hope I could help

If safe mode does not work, you can try to disable hardware acceleration in firefox > options > advanced > general and or disable addons that could cause the problem. It would also be interesting what graphics hardware (description of the adapter, driver date and version of the driver) you use - you can access this information in firefox > help > correct information to the bottom of this page...

It's an old printer and there was only the 32-bit drivers for Windows 98 to Vista. Canon are unlikely to write 64-bit drivers now.

My Instagram app will not open it keeps saying: "pending". I have tried to delete the app, off my phone and still nothing! Please help thanks
You said that you tried to delete the app
If you have not been able to
Settings - general - storage - Storage - find the app - delete
Do a forced reboot - after all open applications using the app Chooser - invoked by fast double pressing the home button and drag upwards on each app until it disappears from the screen.
Meet the sleep/wake and home buttons down until you see the logo - then release and allow normal start upward
Then re download the app

original title: run a legacy cpl high?
Hi all. on my control panel I double clicked on update of programs and I wonder now run a legacy cpl high. When I click ok it says script errors and nothing works. If I click on details until I click on continue it says; "C:\Windows\System32\RunLegacyCPLElevated.exe" Shell32.dll, Control_RunDLL "C:\Windows\system32\ISUSPM.cpl",Program updates I'm not very technical and well I tried to look on the search engines, I can't find anything to help me.
Hope someone can advise me please
Thank you aypee74
I figured how to stop my warning high. I just got an answer and it reminded me that I now know why my computer was giving this prompt. This may help a bit there. So I decided to write.
In my case it was my 'Sigmatel Audio Control Panel.I had disabled "allow reconfiguration pop ups".This will make the warning "Run a legacy CPL high" lights up to chance that your system can access this audio program. Once I've rechecked. The warnings went away unless I open the control panel. But it's a normal warning according to the manufacturer of my computer.Some of you may have something much more serious, but for the few who becomes confused by the latter and have this audio driver, this may help. -
As indicated in the subject line, all of the lights on the front panel are flashing and nothing works. Will not communicate via cable or wireless. Green light is visible on the power supply. Suggestions?
It seems that the printer needs to be reset.
Cut the power to the printer for a minute. Reconnect the power to the printer and turn it on.
Does have an effect?
