Dell Pc Studio 450s Will Not Recognize Network Connection After Power Outage?
Sep 21, 2011
Dell pc studio 450s will not recognize network connection after power outage. Have run diagnostic fix multiple times but to avail. I have roadrunner cable broadband connected to voyage router and then to wireless router. Wireless router and vonage works (as evidenced by this email using iPad)
Have already reset everything multiple times including unplugging modem and pc.
From what I understand the pc is getting gatewayaddress or does not recognize.

The power went out in the room where my desktop and router and modem and everything is located. The electrical outlet that all of those things were connected to suddenly stopped working so I had to relocate everything to the other electrical outlet in the room. Everything is working fine again, including the internet connection on my desktop, but now my laptop in the other room will not recognize my wireless connection. It gives me a list of available networks, but none of which are my own. Which makes no sense, as everything is working as normal on my desktop. I tried to "manually connect to a wireless network" by typing in the name and proper security type/encryption type and password, however it tells me a network called (my network name) already exists, and it says "use the existing network. Open the 'connect to a network' dialog so I can connect." or "choose a different name." When I choose the former option, the list of available networks pops up again but mine is not on there. And it should be, as I'm definitely in close range of my router.

I have a Studio 1555 64bit running on Windows 7, within the past few weeks, my wireless connection sporadically turns off, the wireless router is ok, I can connect wifi to my phone. My computer does not recognize any wireless networks, although there are several in the neighborhood. Sometimes it randomly comes on.

I had to re-install Vista on my Dell Studio 1535, and site the re-install i've not been able to connect to wi-fi because Vista apparently doesnt seem to recognise the wireless adapter. In Device Manager it lists the generic "Network Controller" and has a question mark next to it.
I've installed Dell System software, Dell Notebook System software, Quickset, chipset drivers and the R206848 file that includes the 1397 drivers, yet its still not recognised.

I have a Cisco EA4500 wireless router. The only issue I have had with this router is when power gets disconnected or if I have a power outage, I have to go through some loops to get it to work again usually taking upwards of 45 minutes to fix.

I am using Scientific Linux 6.2 (Variant of RHEL / CentOS) . Every day at a particular time there is a power outage at my place, and after 1 hour power is restored. My laptop is connected to a network switch, that has no Backup power, and connection is disconnected when power is gone. Laptop keeps running in battery power.
Now when power is restored, the ethernet connection (eth0) is not automatically restored in linux. It only says connection available under wired connection. The same thing happens to the Wireless Network Connections. What can I do to automatically connect to these networks, whenever they are available?

Immediately after a power outage, my internet connection predictably drops after a set period of time or usage. It is either after about 30 min or 5-15 mins of watching Netflix. I have a modem hooked up to a wireless router and use the network on my iPhone, laptop and Roku. Since the problem, I have dropped to just having my laptop connected but this has not worked. The wireless network will disappear after the 5 - 20 mins, the light on the modem and router will show no internet (all other lights are normal). Internet connection will be reestablished if I either unplug both the modem and the router (not just one or the other) OR if I unplug the ethernet line from the modem to the router and plug it directly into my laptop (the internet light on the modem will go from "off" to "on"). Despite internet connection working from transferring from the router to the laptop if I connect it back to the router, the internet lights goes off again (resolves upon unplugging and plugging modem and router back in). The internet has not yet dropped when it is physically plugged into my laptop.
I have tried the following:
-Powercycling (temp fix until it crashes again)
-Plugging into a different outlet (I cannot connect it to a different phone line, only have 1 with DSL. Also, I do not have phone service or cable, just internet via DSL)
-Resetting modem
-Resetting 2 different routers
-Calling ISP, their test of the modem was inconclusive
Again, my wifi does not see my network whenever the internet is dropped or the ethernet cord is unplugged from the modem. The outlets I have it plugged into has some type of electrical issue, two electrical devices have shorted out in the room they are in. I do not think this issue is electrical, everything seems to have constant power (unless the power outage shorted out something in the modem). Below are some details of my modem and router. I will provide any additional info requested. I will gladly buy a new modem but I want to see if it can be fixed first.
My modem: Westell
WireSpeed Dual Connect
Model: A90-210030-04
DSL Statistics
Line State: Up
Modulation: G.DMT-Mode
Data Path: Interleaved
[code].....
Router: Linksys E2000 Internet Connection Type: Automatic Config - DHCP (I tried PPPoE and it never got a valid IP address from my ISP)

I'm running Windows Vista desktop on a wireless network. It's been working fine for months. Just lost power for a minute today and ever since I can't connect to the internet, only locally. My desktop can't even identify the network. My laptop (I'm using it to send this message) is also wirelessly connected and works fine, as do other wifi enabled devices in the house. I've done the power off and on for the modem and the router but it's made no difference. I've rebooted the desktop system too. I've run the ipconfig /all and am concerned I have no Default Gateway listed.

Sometimes the connection will be lost altogether and when I try to reconnect it says "unable to connect" and I have to wait 5/10 mins until the laptop connects it's self again automatically.Other times, the signal strength shows as full (in the bottom right) but a yellow triangle appears with an exclamation mark in it and the status reads "Currently connected to Talk Talk 388380 No internet access". It stays like this for several minutes, then goes back to normal!?I've recently had fiber optic broadband installed, but I don't think this is the issue as it was happening before.Even when the internet is working, the connection speed is really poor; YouTube videos constantly buffer, even on low quality.I've plugged in the ethernet cable today and it appears to work fine, so I think it must be an issue with the laptop[CODE]

I have a Studio Xps435MT connected to the internet through a 2Wire DSL modum using an ethernet cable. Installed a new hard drive last week after drive failure, Reinstalled Dell drivers and utilities using disc, then operating system, software, updated drivers, installed SP2.
Internet connection worked fine since then. Yesterday and from then on, Windows and modum will not recognize network adapters so not internet availability although device manager shows them working. Modum does work with my laptop so I can access internet through that.
Network and sharing shows unidentified network and limited connectivity IPv4 and 6, on IPv4 no default gateway or DNS server identified, no IPv6 gateway. Tried reinstalling modum but shows no network adapters identified.
Windows system info shows that intel 82567LF 2GB connection installed and reset today, default IP gateway not available.

I have a Dell Studio 1555 and normally my wireless connection works perfectly. It runs on Vista and I bought it in August 2009. Just recently I went to a friends house, and my wireless detected their router, but where normally it shows connection signal bars, it showed a red 'X' and wouldn't allow me to connect. It wasn't their router because their wireless on their computers were connecting to it fine. Then I went back to my house, my wireless was working fine, and connected automatically right away. The next weekend I went to my parents' house, where I have brought my computer and was able to connect to their wireless countless times in the past, did the same exact thing as when I was at my friends' house. Normally it will detect their router by their name because that is what they have it set at, but now it can only detect it as linksys. And it will not connect. I have no idea what to do because as soon as I go back to my house, my computer is able to connect to my wireless

I live on a college campus and we had a brief power outage today. The power is back, and we (there's 4 of us in the apartment), can only connect to the internet via ethernet cable. All of our computers show wifi as connected but no internet access, the same goes for our cell phones. We've tried resetting the modem, reconfiguring and everything.Still nothing works. The router is a JCG 108 M.

I have a dell studio 1557 running windows 7. I live in my own apartment with roommates in college, and i've been having some very bad issues with slow internet or constant down time. Here are some key points:
- I have Charter internet.
- My 2 other roommates have NO ISSUES.
- My laptop works in my family's house. They have Comcast. I went on vacation a week ago and there were no issues on the hotel internet. No issues from the school's internet.
- I have been using my android phone as a tether because the internet is more stable. It's slow, but consistent for the most part. This is extra frustrating because I shouldnt have slow internet. And I sure as hell shouldnt be paying for internet I can't even enjoy.
- Charter has replaced 2 routers. Both are brand new. They are net gear. Charter is clueless to my problem.
- I have reinstalled windows. Dell told me to try safe mode. I noticed NO ISSUES WITH STANDARD BROWSING IN SAFE MODE. This leads me to believe it is a software issue.
- The connection is non-existent when coming out of hibernation or rebooting. In the morning, i have to boot up, make my coffee, and only then will it give me access to the internet. Otherwise, page timeouts. It can take up to 10 minutes for the internet to work.
- Youtube and general multitasking is very bad. Slower connection than ever, page timeouts, and I often need to wait for a video/music to buffer before I begin enjoying it.
My laptop has been this way for upwards of 6 months.

Computer: Laptop Dell Studio 1555 Dual Core: W 7 64 bit, router Sitecom WL-351. Max. connection 120 Mbit. Speed normally approx 100 Mbiton the Dell desktops. Connection speed on the Laptop Studio used to be 60 Mbit wireless . Haven’t checked speed for many week but yesterday foundout that the speed dropped to 12 MB. Wired the laptop to the router, connection wend up to 98 Mbit.
Wireless again the speed dropped to 12 MBit. Checked the wireless connection with another laptop and it went up again to 70 Mbit. What could be wrong on the Studio 1555?
Cleaned the computer, no malware, Mode AP, Channel 11, WPA2
The card Broadcom driver 10-01-2008, version 5.30.21.0
The card works but the 12 Mbit should be at least 60 Mbit.

I have a 500 GB HD connected to the router to the usb port and It bothers me that whenever electricity fails in our city and it comes back I can still navigate and access my files on the LAN from the hard drive, but I lose the connection to the router management either by my smart phone application or by accesing trought my laptop. The only way I have figured out to solve this is connecting the drive directly to my laptop and erasing the configuration files created by the router when you set the shared folders, etc. then plugging again and setting all shared folders etc.

I have two RV180W's which are excellent units in almost all respects. The one really noticeable problem is that when I have a power outage (which I have quite a lot in rural France) my RV180W does not automatically restart when the power is restored. Is it not possible to fix this in the next firmware upgrade, or have I missed something in the router menu/setup which I should have set.....?

Two days ago there was a quick power outage here, just one of those flicks off flicks back on deals, but when it came back on I noticed my internet wasn't working. Couldn't figure out what the deal was so after trying a few other things I ended up eliminating my Linksys WRT54G router and just using my DSL modem. Internet works fine.
Now, I've always been kind of sketchy on networking stuff, but I don't think there router is broken I just think it's been reset or something and now I don't know what setting I need to change to get it back to working order.
Here's the kicker though. I had the DSL modem in bridge mode and the router handling traffic before but I had a huge issue with that where my Steam would only download at 10-15 KB/s. Not only that but it would take forever to login and crash constantly. This would happen on my brother's computer too, which is on the same network. I could never figure out how to fix it as forwarding ports had no effect and every other fix I could think of amounted to nothing as well. Hell, I even did a fresh install to no avail.
Now going straight into the modem my Steam is downloading at full speed and there's no slow login or crashing issues. The thing that boggles my mind though is that more than once before I tried doing this very same thing, going straight into the modem, and it didn't fix the problem.
Ideally I want to get the router back up and running and keep my Steam in full working order, essentially to have my cake and eat it too, but the priority is to get the router back up in running as I have another PC on this network, plus a 360, a PC, a wireless printer, and two Wii's.

I recently replaced my hard driveon my Dell Studio 1749 and have installed all of the disks that came with my laptop, but for some reason I don't have a wireless network adapter to connect to available wif (I had wireless prior to the hard drive replacement). The only network adapter I have in device manager is Realtek RTL816D/8111D Family PCI-E Gigabit Ethernet NIC (NDIS 6.20) I'm fairly new to this so not sure if there is an easy fix to this.

I am on a surge protector and we lost power last night. This morning we were stilling experiencing a brown out but now the power is back 100%. I've walked through the E1000 router reset and not matter what I do, all the lights except the power light blink rapidly and dimly. Could the router be fried even though it's on a surge protector???? It's less than 6 months old so hopefully still covered by warranty.

We had a power outage the other day, and now the wireless router cannot connect to the internet. Network Magic shows there is no connection from the device to the internet. I tried repairing it through Network Magic but it wasn't able to fix it.
My PC is directly connected to the wireless device by LAN cable. If I connect the PC directly to my DSL router I can connect to the internet, but not if I connect to the wireless router and from there to my DSL router. I tried resetting the wireless router to factory defaults and then going to [URL] and resetting up the router security settings. But Network Magic still shows the bad internet connection.
I then tried resetting the router to factory defaults again and installing it from scratch using the setup CD but that failed as well. I'm not at home right now so can't remember exactly at which point it was but I think it was either when the setup wizard tried to detect the device or install the device.This is the second time I've had to reset up my router due to power outage. Last time I was able to get it working by doing the first steps above.

Latest firmware with CCC corrupted after power outage. I reseet the e4500 several times and tried to reload the firmware and still no good. Only way I got it back up is to install the older non-CCC version 2.37. Strange all was fine until the power outage. Not sure if I should even bother to upgrade to 2.38 again.

We had some problems with 3560G-48PS-S switches and PoE for our phones. IOS is 12.2(50)SE3. There were some problems after power outage. The switches didn't reboot because we have two eletric circuits. But after the problems we had no PoE on all ports.
The switches logged to following syslog message:
%ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Gi0/17: Power Controller reports power supply VDD under voltage
I can't find any informations in the error message decoder for that. But there was another thread here with quiet the same message, but another problem regarding RPS2300.
After reloading the device all works fine again. The workaround with the commands "power inline never" and "power inline auto" I didn't know till today.
Some information about that syslog message?
My guess is that there was a voltage swing and the switch powered down its supply? Is that possible?

I recently copied a configuration from a router 2800 to a 2900. After a power outage no one can connect outside of the network through the new router. Before the outage all was fine. I put back the old router and all is fine which eliminates any cable or switch error. I have the router totally disconnect. I notice the configuration is in place. My question is there any diagnostics that I can run to see if there is any hardware failure. It seems to boot up fine.
