Acer TravelMate P645m :: Internet Connection Not Stable - Yellow Triangle Exclamation Mark Shown
Nov 15, 2014
My acer travelmate P645m internet connection is quite bad. It happens quite frequent as well.
When I connect my laptop to wi-fi (my own router and in the library), it always has a yellow triangle exclamation mark all of a sudden. As my phone connects to those wi-fi too, I have checked the internet is still working fine when it happens on my laptop, so I am sure it is my laptop that doesn't connect to the wi-fi stably. I will have to turn off the wi-fi and turn it on again to make sure it has access to the internet.
I know it is not a complicated process of turning off and on the wi-fi on my laptop but because I just bought the laptop two months ago, if there is any hardware problem, I would like to fix it within my warranty. Why the internet connection on my laptop is so poor?

I received my G570, and have had internet issues since. It can connect to my WiFi network, however after using the internet for a few minutes, it consistently gets the yellow "!" over the wifi icon in the task bar and says no internet connection and I loose my connection. I know it is an issue with THIS laptop since my old and decrepit HP laptop which sits next to it works perfectly fine using the same network, as well as my smartphone and room mate's devices.
I have downloaded the Lenovo update software and attempted to use it. I get a message saying something along the lines of no available packages, assuming that means everything is up to date in terms of drivers.
I have done some research with the terms "lenovo, g570, wifi, internet, problems, connection" and yield many pages, however none have seem to provide a solution that works for me.

I've just had a look at device manager and noticed there's an exclamation mark next to the dvd drive, I havn't used the drive for about a week so I'm unsure when the problem occurred.
I uninstalled it from device manger after downloading the driver from dells website but when the app runs it says 'drive not found' so I'm unable to reinstall the driver.
I've ran a live linux cd which worked fine so it must be a windows thing?
I've also refitted the drive to make sure it hadn't come loose.

I have successfully completed a fresh install of Win XP Pro on by laptop and the final driver that just will not install is the Intel Chipset driver. I have downloaded the latest driver from Dells website using my laptop tag to get the correct drivers.
In device manager I have a yellow exclamation mark against SM Bus controller. However, when I install the chipset driver at the very end, the install says 'error, install will now end', then you click close and then it wants to reboot. SM Bus controller remains with an exclamation mark in the device manager.

Recently I got my new inspiron n5110. after i had installed OS, i installed drivers, with bluetooth driver amongst them. I managed to make everything work just fine, except bluetooth radio. I downloaded original driver from Dell support page and installed it, but device manager shows "Generic bluetooth device" with a little yellow exclamation mark. when i go to the properties of the device, it says "Windows has stopped this device because it has reported problems. (Code 43)". i tried a lots of things but none worked. then finally i tried to uninstall driver, and found out that uninstaller throws error: "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." i'm running win7 enterprise x64 ....

I have an ideapad z500 which I'm happy for, but it annoys me that when 'm at my college I can't properly connect to the wi-fi the school has. When I connect, I'm on for usually about half an hour, but then I get the "limited connection" yellow triangle and I have to deactivate the networkcard before I can get a normal connection.
Other times I simply just can't connect, it tries but it fails. When it does, I have to reboot the computer before it succeeds, and that's no good when you are working on a project. At home i have no problems, it works nicely.
Also, how to enable the WiDi on the z500.
My PC is running Win 8 with the Intel Centrino n2230, Intel 3rd. gen i7 (3632qm)

I'm new to Dell and all of a sudden a great many files have a blue clock face and red exclamation point on top of file thumbnail. What does it mean and how do I remove them. Can I remove them in bulk. I backed up my whole computer yesterday, but the blue clock and exclamation point still remains on many many files and folders.

I had my pavilion zv5000 upgraded from windows xp to windows 7 but the thing that is wrong about it is that it says no driver flies are required or had been loaded to this device. And their is a yellow exclamation point on the base system

My XPS just arrived yesterday, and i am having lots of trouble with the wireless connection. I have tried being close and far from my wireless box and it doesnt fix the problem. My connection is great when its working, but it disconnects for about 20 seconds very often. Its extremely anoying, and I dont want to have to return this laptop as I really like it. Is there a location where I can update my notebook to hopefully resolve the problem?

I just received three new T440p laptops using Win7 Pro. Unfortunately, the wireless link to keeps disconnecting ever so frequently on all the machines. I have updated the Wireless drivers, reinstalled the BIOS and even optimised power options to enhance the wireless perfomance but none have worked.

The laptop is a Acer 5520-5912 running Vista Home Edition.
I am trying to figure out some issues with my father's new laptop when connecting to the internet. There was a problem with finding wireless networks which was attributed to a problem with the wireless network card driver. I deleted the driver, figuring I would just connect to the wired network only to find that the laptop will not see my lan connection.
I tested the lan connection in my laptop and it worked great.
When I go into the network connections it shows 1 broadband connection that is disconnected through something called a WAN Miniport (PPPOE). I have no idea what this Miniport is, and when I try to connect, it does not connect.
The second connection shown is the Local Area Connection (LAN), and it says the network cable is unplugged.

I have just purchased an Acer Aspire E5-511, it repeatedly loses internet connection (wifi) despite still showing as being connected. I have read that numerous other people have experienced this problem but I have not found a solution that works. I have tried updating the driver and changing the battery power settings etc. I have spent ages transferring all my files accross so am reluctant to have to send it back now.

I have a travel mate loaded with erecovery management. I keep getting a message "internet control panel has stopped working". This appears to be an appcrash; the guilty party being rundll32.exe. In addition "computer" has gone from my start menu and from windows explorer. Start menu.
I have carried out a sfc/scannow which says there are corrupted files that cant be repaired. System restore has not worked either. There appears to be 3 different options open to me to "restore" my system.

I bought my HP HDX 16 about a month ago.
And, I am very satisfied with all features in this laptop.
I have one question, is about how to connect Internet using my Sierra 885 modem.
When I run Ping, there is connection.
The weird one is, I browse via Firefox, IE, even Opera it says there is no connection.
I checked on Control Panel, and yes there are connection, Local Area Network 2,
Connected, but again why my browser cant connect Internet?
I try to fill the IP ADDRESS and DNS, accroding to my communication operator's websites, but still no change.
When I try this modem to another computer it can connect perfectly,without fill in IP ADDRESS and DNS.
Is it different if I want to connect using Windows XP or Vista 64 bit?
And this modem is support for XP and Vista.

Up until this past Saturday (6/14/14) everything was working fine with my HP Envy dv4. Now I cannot connect to the internet anywhere. Having read the posts I have already looked up what seems to be some the necessary information to solve the problem: Product #C3Q25UA#ABA; Bios F.24, Ralink Tecnology w/driver version 5.0.37.0.

I have been having this problem for a long time now and a friend pointed me here to beg for some advice. My internet connection works fine for general browsing purposes and i have a good quality of signal strength where i usually use it.
The problem is, every time i run a game such as Football Manager or World of Warcraft my internet connection will be lost. This can happen as soon as 5 minuites after starting the game or can take up to an hour, but without fail it will happen. After this disconnection my wireless adaptor is still shown as being turned on however i am unable to detect any networks in range. The problem is not solved by turning the adaptor on and off and i am forced to restart the system.
I'm not sure what the cause of the problem might be, CPU and memory usage looks normal. I was wondering if perhaps overheating could cause issues like this? My laptop is generally quite warm but with the graphics card coming into play as well... I tested the internet connection whilst connected to world of warcraft but keeping the game minimised and i was not disconnected. I also installed Speedfan to monitor my core temperature and it measures at 55C idle, but after one minuite of switching to and playing the game this rose to around 75C. Not sure if i should include anything else sorry if i overloaded this a little but not very good with computers so wasn't sure what info i should include.
its a Broadcom device. The driver version 5.10.38.26

I cant get a connection on my laptop. It says that the connection is turned off, but I have no way of turning it back on! I have tried installing the drivers on the Dell website by entering my specific security tag, but they say they aren't compatible. I have even gone as far as to restore it to factory settings and nothing still.

I have a new HP Pavilion 23 Desktop, running windows 8.1. I want to make a recovery set of DVD's, and the instructions tell me to "TURN OFF THE WIRELESS CONNECTION TO THE INTERNET". How do I do this without turning off the wireless router used by other PC's in my house ?

As above I keep losing internet connection on HP Pavilion g6 Notebook PC and often have to turn off to get it back. I have had the laptop for over a year now and have had this problem from day one. Often there are no connections to be seen at all. I can be on a site fine one minuete then the next it just freezes. Sometimes clicking dissconnect then reconnect will resolve the issue. But most of the time I have to switch off, leave it off for a few mins then reboot. This does not always work so I have to do it again.
As above, I have had this issue from day one. When I got it home there were no connections to be seen. I took it streight back to PC World they switched it on and connections were there. When I got home, switched on others were there but not my own. After switching off and on again mine was there. After that it was okay for a week or so then I started getting the problems I have now. My son sitting about three feet away from me on his lap top has no problems at all so I know it is the laptop and not my router. Also my wifes, my son's and my phone are on the internet through the router when this goes off. Now and then it will be okay for a couple of days but most of the time it goes off several times a day.

Since changing my password on my router, I can no longer get online with my Dell Inspiron 1520. All other computers and phones work on the wireless. Also, my internet provider saw that I no longer have the Microsoft TCP/IP Version 4 which I need to work with their internet.

I have an HP G71-449WM HP notebook. It was all messed up and wouldn't let me restore to an earlier point at all so I reset it to the factory settings. I didn't make a back up because there was nothing I wanted to save. I am unable to connect to the internet now, wirelessly or by hooking up to an ethernet cable. It gets an error while going through the initial set up where you set your password for the pc, the time, etc. when it gets to the spot for connecting to the internet it gets an error, freezes up. I turn it off and turn it back on and it just loads like a normal computer, but can't connect to the internet no matter what. I've reset it to the factory settings about 5 times in the last 3 days and am getting the same problem each time. I have no recovery disks or anything.

HP probook 4330s
Windows 7 Ultimate + service pack 1 64bit
Driver: RALINK microsoft driver 3.0.0.41 (up to date when i do a search)
When I remove the ac power external internet is lost. The wireless connection still appears to be up but there is no traffic. I cannot ping anything when this occurs.
The only way to get this up and running again is to
1. insert ac power
2. restart the dhcp client service (sometimes have to do this more than once). The service hasn't stopped, but for some reason this gets it up and running.
I have also tried disabling the "allow computer to turn off this device to save power". But this did not work....

I got my hard drive replaced yeterday but now I have no internet connection, it is a dell inspiron n411z. I have the drivers and utilities cd and have tried installing all of the drivers on it, some have checkmarks and some dont so i am confused. What do I do if i installed them in the wrong order? My internet is still not working and there is a yellow box with an exclamation point by the following items: ethernet controller, network controller, pci simple communications controller, sm bus controller, universal serial bus controller, and unknown device. I had this problem last time the hard drive was replaced and somehow fixed it using this CD but I cant remember how.
