Ethernet And Wireless LAN Only Work When Laptop Is On AC Power?
Sep 10, 2012
As I started working on it, I seemed to experience very erratic, random issues with the network connectivity. After several reinstallations of Windows 7 and Sony drivers, however, I have identified the pattern. When the laptop is on AC power, connectivity is not a problem. When I'm on battery power, however, the network adapters cease to work and actually completely disappear from Device Manager. The is true even when the battery is fully charged and everything else works normally.I have already tried going into all the power management settings for the laptop itself and for the network adapters and made sure that they are not being shut down when the laptop is running on battery power, and yet the problem persists.
i have this problem where the wireless wont work after the power has been turned off and then back on. they use a power box for the main pc, modem and router and turn it off before they go to sleep to save on electricity costs. usually, my fix is to unplug the router, turn the modem off.. turn it back on and the router back on. from time to time the wireless will work after the power has been turned back on, but its either very slow or the connection goes in and out. i'm sick of having to reset everything before i want to use my laptop.
My laptop won't work with the Ethernet cable and say it has an IP conflict. All my computers have an IP address starting with 192 and the laptop has an IP address starting with 169. I did an ipconfig and on ipv4 is where I got the IP addresses. I tried to do an ipconfig / release but it won't release the IP address because of the wireless media.
I have an HP laptop and out of the blue, it will just not connect to the internet wirelessly. It will say connected but no internet access. This happens and random times, at least once a week, and for exactly 24 hours between 1 a.m. one day to 1 a.m. the next day. I can connect via ethernet cable just fine. My phone and TV can connect wirelessly, but not my internet.I have tried resetting my router/modem multiple times when this has happened to no avail. I have factory restored my computer. I have deleted my driver and reinstalled it. Literally the only thing that has worked thus far is connecting to an ethernet cable. I called my ISP and they said my router is fine and nothing is wrong with it.Before you ask, NO, I don't have any monitoring software or any software that prevents the use of internet after a certain time. Keep in mind that my computer is totally factory resetored, totally clean, nothing on it but what it came with.
I have a HP G62-371DX Notebook that I have been using to access the internet. Lately I have been experiencing random disconnects that will last from maybe 30 seconds to 2 minutes. They will happen maybe every hour or two and are becoming really annoying. At first I was using the laptops wifi abilities to connect to my router. So when these disconnects began to happen I tried plugging in an Ethernet cable into the router and still experience the same disconnects. The only other devices in the house that experience this is the xbox 360 which is connected with an ethernet cable aswell. The router that I had was an old netgear router, but in the past week we got a new router which is a SMCD3GNV. I have only had it working today and I had the problem maybe 3-4 times within the first 12 hours (with both the wifi and ethernet connection). I have tried updating the firmware and resetting the router and modem.
So, we have multiple computers that the wireless capability stops working randomly and can be fixed by going in to the BIOS and resetting it to the defaults.
i recently reset my acer aspire 5750 to factory settings and im having a real problem connecting back to the internet.The laptop wont evan give me an option for connecting with wireless for some reason?? I need to get back on the web asap for work.
Can we connect Power over Ethernet (PoE) Adapter just like this one D-Link Power over Ethernet (PoE) Adapter Kit with any Ethernet switch ? I have a Belkin 5-port 10/100 switch can it be powered by PoE?
how to keep my Ethernet card powered after shutting down my Computer. I would like to use wol(wake on lan) to turn my computer on while I'm away from home so I can use remote access to edit some files. I have configured the wol and am receiving the packets, but every time I turn off my PC the LAN card turns off as well,thus not letting me wake up my PC.
I have had this problem not being able to turn on the wireless radio for months. I have to get it turned on now. When I press <fn> F5 I can see the wireless radio is off. I see the power on button. When I select the power on button nothing happens. I expect the wireless radio to power on.I have tried fixing the winsock. I have run this MS fix at: How to determine and to recover from Winsock2 corruption in Windows Server 2003, in Windows XP, and in Windows Vista And I have run this bat file
** Start of bat file called renew-ip-reset-winsock.bat ipconfig /release pause ipconfig /renew
From many days the battery icon is missing from the taskbar, the notification icon is greyed out even if the laptop is not on AC. i followed the the tutorial System Icons - Enable or Disable but nothing happened.
I have a Acer Aspire 5920G with a spoilt ethernet port. I find wireless too unstable ... so I want to use ethernet. I cant find a USB Ethernet Adapter in most hardwarestores in my country but I found Apple USB Ethernet Adapter but will it work on a Non Mac?
when im connected through an ethernet cable i get what im paying for 40mb, but then i use a wireless pc, ipod or ipad i can barely get 20mb...so im loosing half of my speed, i've been told that is normal is that true?
My daughter has a Hp laptop and it was working fine, but the screen was coming apart. so my husband put it back together, Now it will not come on. It's getting some power but not coming on at the power button. The lights flashes when you push the button then nothing.
In our office we have our PC's connected to our inter-office network server via the Ethernet ports (Local Area Connection) with a hard wire to a hub, that in turn runs to our server. We also each have a wireless internet connection on our PC's via a USB wireless adapter. When we were using XP this was not a problem to have access to the server AND the internet at the same time.
When my PC died last year I bought a Dell Inspiron 560 slim tower with Windows 7 to replace my XP machine. The first problem I ran into was that I could no longer use the wireless internet connection AND the hard wired connection to our server operating at the same time. If I stayed connected to our server, I will not have a wireless connection. If I go into the "Local Area Connection" properties and "disable" the connection, I almost instantly get my wireless connection back. The big issue when doing this is if I leave our database program (ACT!) open while the server connection is disabled, I have to shut down ACT!, then restart it before I can connect it to the server. If I try to without closing and reopening it I get all kinds of errors.
So, in the mean time, I have just put a shortcut on my desktop that allows me to enable and disable the Local Area Connection when I need internet access.
A couple days ago, my boss's PC grabbed a virus that slipped past McAfee (that program is now gone!!) and really hosed up his PC. He bought the Windows 7 upgrade software and wiped the hard drive and installed Windows 7. He is now having the same issue as I am.
For what it's worth, he is using a Belkin Wireless-G USB wireless adapter, and mine is a Netgear Wireless-N USB adapter.
Is there any way we can have the two connections operate at the same time like they did in XP? It really becomes a pain sometimes when we are on the phone with a client and we need to jump back and forth between info that is online, and info that is on our server that we access through ACT!.
My system specs are updated. My power setting quit working a few days ago. No matter were I set sleep mode or power monitor down, it never does. Not sure why? I've performed an sfc/scannow with no errors. Nothing has really changed in my system recently except my vid card driver. I can't say that caused it, but I rolled it back just in case with no change.
Brand new PC. Windows 7, 64 bit. Power options worked till I downloaded "Web Shots", then they stopped working. (I've used this program for years with no problems and would really like to contiune using it.) After about 45 seconds of downtime, PC goes to sleep and requires a password when you wake it up. No matter what power options I change or put in, the PC continues to have this problem.
I have Brother MFC7340 printer connected to my HP home premium Windows 7 64 via a USB port. There is no ethernet connection. I want my Windows XP computer, connected to the local home network via ethernet hard connection through my wireless router to be able to print either with a hard connect or wirelessly to this printer. I am having trouble figuring out what to do and have tried various strategies to no avail.
I have a Dell V313w printer and using PowerPoint (office 2010), when I select "Print on both sides" it prints out on one side. I am unable to figure out why it does this. Any advice would help so that I don't have to print out 20 pages a week for lecture notes for a class.
my new laptop will not recognise telstra broadband usb wireless! i have gone into device manager and then network adaptorsand it has an explanation mark on sierra wireless!!
I am currently trying to use my laptop wireless to provide Internett access to my Desktop computer (wireless). I remember doing this on my XBOX 360, all though I am not quite sure how to do this on Windows 7 64 Bit ultimate.
I have connected a ethernet cable from my laptop to my Desktop Computer, and they are both lightning green.
If anyone could be kind enough to provide me with information on how to do this step by step, I would really appreciate it!
I have a Toshiba Satellite a135-s4527. It has a Realtek 10/100 ethernet card in it, and an Atheros wireless card.
My ethernet card doesn't show up in device manager, but the wireless card does.
I went to Toshiba.com and downloaded the appropriate drivers for Windows 7 and my model of computer and installed them, but the ethernet card still doesn't show up in device manager and I'm limited to wireless connections.
I am using a Dell Studio 1557 model. I downloaded the Windows Live Essentials update yesterday and it prompted me to restart my laptop. I meant to click "Postpone" but I clicked "Restart" accidentally. This was in the middle of while I was running Firefox and running Winamp (as far as I can remember).So when the computer was back on I noticed I totally lost the internet connection. Even though the CAT5 cable is connected, the laptop does not recognize it at all. It simply says "Not Connected". And just today I realized that whenever the Ethernet cable is connected to the computer the computer periodically(every other second or so)makes a faint buzzing noise. This is something I had not noticed before. I replaced the cable with a new one and the same thing still happens.I think the modem is working fine since my roommate can access the internet. On the modem where the lights should be on for my connection, it is periodically blinking.
