Dell :: Dimension E510XP - After Power Failure No Wired Connectivity
Dec 17, 2011
After a recent power outage while my PC was in sleep mode, I don't have wired (Ethernet) connectivity.
I have new Dimension E510XP Media Center Edition, Version 2002, SP3 ver had an issue with wired connectivity on this PC after coming out of sleep mode. Of course, the power failure was unusual.
Observations:
- ipconfig /all shows that I have an IP address
- I can ping the DHCP server listed in ipconfig /all and I also can ping google.com.
- I was going to go a restore point set before the power outage. But, somehow system restore had gotten turned off. Oh, well. I did go ahead and turn system restore back on.
Things I've already tried that did not solve the issue:
- Reboot
- Uninstall/reinstall the network adapter driver. Device Manager says the network adapter card is working properly.
- Looked for an updated network adapter driver on Dell's website. Turns out that I have the latest driver already.
- Followed many of the steps from Microsoft at [URL]
- Checked McAfee Security Center firewall permissions list to see if something got changed. Everything looked okay. Also disabled the firewall just to be sure,
- Disabled SafeEyes internet filter.
- Reset the router. Also swapped router ports with a known good PC. The known good PC still had connectivity, the affected PC (the E510) did not.
I am not very computer literate, so this will seem like a stupid question. How do I determine whether a computer has wireless connectivity?
I have a Dell Dimension 9200 running Windows Vista that I bought in 2007. Previously, I have connected it to the internet using an ethernet cable to my router, but this is no longer possible now that my new computer is using the ethernet connection. I want to establish a wireless connection between my older Dell Dimension 9200 and my router, but I don't know how to find out whether the computer is capable of wireless connectivity.
I've got the power cut while PC was running (w7). After rebooting I'm not able to connect to the internet anymore.
In Device Manager, under Network Adapters there is a "Realtek PCIe GBE..." device properly installed. But under Other Devices there are now more entries with exclamation mark:
I tried updating the drivers, then deleting and reinstalling but no success so far. Still can't connect to the internet. The browser can see the router, at 192.168.1.1 I don't know where the problem is.
We have several SF-300-48P switches, eveytime there is a power failure the switches need to reboot 2 or 3 times before they are able to route packets again.
We have cisco wlc 2125 with 13 AP 1131g. All works good. But after power failure one AP can not join to controller, only reset work to recover connection AP to WLC. Additionally, we don't have access to rs-232 port on AP. In this moment on WLC we can see DISCOVERY request from AP and response from WLC to AP, but AP don't send JOIN to controller.
I bougth a used ASA 5505 on ebay which is experiencing this problem [url]... LEVELS or at least the described problem, if i touch the appliance while it is running it will somtimes go to this non working state as well
I have a WS-C6509-E (R7000) and am trying to implement some proactive monitoring for environmental alerts. What is the output from a Power Supply failure for the following “sh log” “sh environment alarm”.
I'm having the following issue with a couple of 1231's.
Some overall config info first:
This is a small office with 2x Catalyst 2950 (24-port, no PoE) switches and 4 AP1231G (autonomous). The APs get PoE from a PWRINJ3 each. The injectors are powered by the AP power supplies. Injectors and power supplies are mounted in the patch closet.
The 2 switches are connected together over 4 ports (20-23 on each switch), these ports are set to 1Q Trunk mode.
The APs are connected to the switches, 2 to each switch, on port 1-2. These ports again are configured as 1Q Trunk.
All this has been working without problems for a number of years.
A few weeks back, AP2 did not restart after a power cut (everything else did). All LEDs are off, port on switch has no LEDs lit. I did not get around to investigating this furtehr until last week. I unmounted (failed) AP2, took it to the spot where (working) AP3 hangs, and plugged it to the cable of AP3. AP2 came to life immediately. I unplugged it and plugged AP3 back in, which restarted immediately.
So I suspect a power supply issue on AP2. I took the injector and power supply that fed AP2 out of the patch closet. When connecting AP2 directly to the power supply, it came to life immediately. So I figure the injector is defective.
On the same day, I notice AP4 is also dead (again all LEDs off, no idea how long, could have been that day or could have been a few days - it has definitely been working after the power cut that appeared to have killed AP2).
So I order 2 new PWRINJ3s and for good measure 2 new power supplies. Later that day, I took the injector and power supply that fed AP4 out of the patch closet. When I try this combination (AP4, injector4 and P/S4), and connect it to a different wall outlet (and therefore a different port -16 - on the switch) IT WORKS! Should have triggered questions, but did not immediately.
Last Thursday I got the new injectors and power supplies. So I take one of each, hook them upto AP2 at my desk, and AP2 starts up. So I mount new injector2 and new P/S2 in the patch closet, put AP2 back in its place, connect all the cables - NOTHING. AP2 does not start. The "power" LED on the injecvtor lights up green, the "device status" LED remains off. I take AP2, new injector2 and new P/S2 to my desk, hook them upto a wall outlet (connected to switch port 17). AP2 starts immediately.
Meanwhile AP3 has (also) stopped working (no LEDs on at all). As far as I can tell, it stopped working after I briefly disconnected (and reconnected) the patch cable between injector3 and the patch panel in the patch closet. The LEDs on switch port 1 are off.
I have since tried to power cycle both switches (took power off both, waited a while, poewerd both back on). No change.
PS: the APs ran firmware 12.3(8)-JA until recently. AP1, AP3 and AP4 were upgraded to 12.3(8)-JEE after the the power cut that took AP2 out. THis is when I found out AP2 was dead. AP2 was still on 12.3(8)-JA. It was upgraded to 12.3(8)-JEE last week when it was on direct power on my desk.
Firmware asa805-k8 was installed and saved on an ASA5505. Upon power failure the ASA5505 reverts to an older firmware, asa724-k8. 1) Is it normal for ASA5505's to revert to older version upon power failure. 2) ASDM/web browser doesn't work using IE--username and password brings to empty screen. how to revert back to later image.

Thinking back, about a month ago I updated the firmware (I can't check version at the moment). The switch has been working fine since then. Today I needed to move some power cables and the switch lost power. Now ALL of the LED lights are flashing green and I can't access the switch. I've tried setting a static IP on my laptop to 192.168.1.20, mask 255.255.255.0, and accessing the switch on 192.168.1.254, but there's no response. I've tried holding in the reset button for at least 30 seconds while the switch is powered on, AND while powering it on. None of that has worked. Also when I first power it on, the system LED flashes orange very quickly for a second or so, then all of the LEDS start flashing green.
I've got a Dimension C521 used as an HTPC with XBMC (Unix Version).The Remote Software of XBMC supports Wake on LAN.Is there a Way to enable WOL in the C521? Perhaps with a BIOS update ?
By the Way is there a way to update the BIOS in Unix because I don't have a Windows Version on this HTPC?
where (in germany) can I buy a CMOS Battery because the alert that the Battery is on low Voltage annoys me
I have a Dimension 4600i that doesn't want to Wake on LAN. I am running the latest BIOS (A10), Intel Chipset Drivers, and latest Intel Pro/100 VE Drivers. I set the Network Settings to Network w. PXE and the startup sequence is CD-ROM, PXE, Hard disk. I am actually using the PXE, that is exactly what I want. My only problem is I need to do Wake on Lan for the system to wake up and PXE against my backup server. So far, no luck. I have tried numerous utilities and when I send magic packet the thing just sits there, everything else works great, the darn thing just won't come alive unless I hit the power button.
I am trying to get an old computer in my church's computer lab connected to the internet. We have an ethernet cable that works (other computers can connect using it), but I cannot get the Dimension connected. It says that the Local Area Connection is enabled, but I cannot connect to the internet. I tried installing all of the ethernet drivers on the DELL website, but nothing has fixed the problem
I have dell dimension 3000 computer running windows 7 ultimate,behind dir 855 dlink router.I am thinking of upgrading my machine to wireless n but my system only supports pci only cards.Is there anywhere i can collection of pci cards.I googled but it seems pci only are in scarce supply.
Having just solved the missing network controller on my Dell Inspiron laptop I thought I would try the old Dell dimension 455-0 desktop I have. It too is missing the network controller, I can access web through wireless usb but not though cable or wireless. I have the disc but I can't install from it as I get message saying it is outdated. Tried Intel but the download ends prematurely and so doesnt work.
I have a Dell Desktop Dimension E520 with a Windows 7 operating system. Up until a couple of days ago I was able to connect to the internet. I have the router connected to the computer via an ethernet cable. Now if does not detect any wireless routers in my vicinity and there were 7 others. I have a belkin G router.
-Netgear router 1 -Dell Dimension 9150 - Windows XP pro SP3 (this machine, connected to router 1 using a pair of netgear powerline adapters -2 x Dell Inspiron laptops - Windows 7 Home 64bit (wireless) -iMac - OSX Snow Leopard (wireless) -Apple Time Capsule (network drive) -Several misc items (phones, iPod/iPad, Vodaphone sure signal, PS3) -Network printer -Netgear router 2 (used as wireless access point the otherside of the house, connected using a pair of netgear powerline adapters) CURRENTLY DISABLED
None of the 4 computers can see each other, but they can all print and access the Time Capsule. Now I've made sure they're all on the same workgroup and that relevant services for sharing files are running. When I try to "View workgroup computers" on the XP machine I get the error attached.
I just set up a wireless router in my home to my Dimension 510 computer. I know the wirelss is working because our Ps#, Iphones and ITouches can receive the signals.
However, our other desktop Dimension 510 does not appear to be receiving the wireless signal.
does it just not have the capability to receive a wireless signal and I have to use an ethernet cable connection?
Is there something I need to add in order for it to receive the sireless signal (some one mentioned an adapter but I thought an adapter just boosts the signal, and the desktop is the closest device to the network router so it should be receiveing the signal okay).
I reinstalled windows xp (reformatted c). Installed the drivers in this order: Controller, Video, Audio, Network, modem. I selected the drivers that had the check beside them on the driver disk. Now, in the device manager, there is a yellow question mark beside the ethernet card and I can't connect to my broadband connection. Wire is attached... checked that twice. I have connectivity through other computers, so internet is working in the house.
I did a fresh install of Windows XP recently on my Dell Dimension 4550 and I'm having trouble getting on the internet. In the Device manager it has the '?' next to Ethernet Controller. I've read the other articles on this site but nothing has worked as of yet.I did another fresh install of XP (2nd time) and then started with the Chipset for Intel, still nothing.
The order for drivers installation says to install the DSS utility first, but I can't seem to find it in the Drivers & Downloads section for my Dimension 4550.
My ethernet was working fine when I shut down my computer then all of a sudden it rebooted and gave me a blue screen. I rebooted it and it started but then it was not able to connect to the internet. The pci adapter driver was not there. I reinstalled it and it still would not connect. I uninstalled it and reinstalled it, changed the ethernet cord for a new one and tested the new cord on a different device with no problem but stil cannot connect. It says network cable is unplugged. This happened before and the dsl technician was able to get it to work again unfortunately I have no idea how but it had something to do with the configuration.
My (home desktop Dell Dimension E310) other computer had a virus that flatlined the machine. I reinstalled the operating system from the discs provided by DELL. Now, I can't connect to my DSL. The browser wont see the http:/192.168.0.1 ActionTec router. It's plugged directly into the computer via ethernet cable. this laptop is receiving signal from the wireless portion of that router, so there has to be a signal to the computer (it was working earlier this morning prior to DELL disc reinstall).
I use a Dimension 3000 desktop. I cannot dial in to my ISP (Juno). Each time I try, it responds "can't dial in". I checked the connection, that's ok. I checked the phone line and that's ok. A box pops up that says "system service not working go to Help & Support" When I try to go to Help & Support, a box pops up "system service not working".
This all began after I used an AVG PC Tuneup. Since then the bottom line colors changed. For example, where START was green with white letters and the windows colors symbol; it is now WHITE with Black letters only. Where bottom line across was blue, now it too is WHITE.
I can pull up WORD, Games,etc. but am unable to dial in to get to internet.
My hard drive crashed. I have finished installing everything on a new drive that I have from my Dell installation CDs. However, in the Device manager, the Ethernet Contoller shows the the drivers are not installed. I can't seem to find them anywhere on the Dell web site.
when I pull the cover off of the computer - the outside of the Ethernet connection says "418D-J51 10/100 BT"
1、the router power led's emitting light very weak ,
2、client pc cannot get ip from connected router
these error perhaps happened after a plug power jack action. Dc-dc chip is ME5513,the voltage on its pin4 is about 11.94V,and the voltage on following electrolytic capacitor is 3.3V,its seem normal.
I have a ~3 month old e1000 v2. In the last 24 hours it appears to have died, all 4 ethernet lights plus the power light and the one to it's left are on continuously. Before I dispose of it, does anyone know if this really is a hardware fail or is there some way to recover it? I've tried a few resets, power cycles and leaving it off for a few hours in the hopes that would bring it back to life but to no avail.
I have a switch 3560v2 with an IOS 12.2(50) SE1.All the lights ON and console error message below:POST: inline power post failed for port 0 up to port 15.Then, the system hanged and all lights (indicator) ON.
