Dell Pe2950 - Losing Partial Network Connection?
Jun 28, 2012
We are running Sharepoint 2007(sp3 and wss sp3) on a dell pe2950 running Server 2003 std x64 sp2, 4 146gb 15k sas raid 10, 16gb ram, dual xeon 516 3ghz. the network card is a quad port intel 1gb pci-x server nic. Was running broadcom net xtreme dual port onboard, and had the same issue.
We are losing partial network connection, after about 14-15 hours of the machine working correctly. What happens is that it cannot ping, or access, any machines not on the same network segment(this machine is on 192.168.3.* and cannot access machines, or be accessed from 192.168.2.*, 192.168.4.*, etc, etc). what i have found is that when i try to ping 192.168.2.210(our dns, dhcp server). its times out about 20 times and replies 2-3 times, and then repeats the cycle all over again. i have done a winsock reset on the machine, and sometimes it starts back up and works again, sometimes it doesn't.

I am having a very frustrating problem with my new Dell XPS 8500's wireless connection - Dell Wireless 1703 802.11b/g/n (2.4GHz). Basically, I am losing my network connection every couple of minutes. The process goes something like this:
1) Not connected - Connections are available
2) My network disappears completely (yet all other local networks are still visible) for a matter of seconds then reappears
3) I try to connect and receive "Windows was unable to connect"
4) I press "Troubleshoot problems"
5) "Resolving problems", "Resetting network adapter", "Troubleshooting has completed"
6) Problem with wireless adapter or access point - Fixed
7) I am reconnected to the network/internet with a full 5 bars
8) Process repeats itself five minutes later
I have been able to come to a conclusion that is not the adapter, or the router, but some sort of compatibility issue as:
a) I have tried connecting to a different wireless network and it has worked fine
b) There are other systems in the household that connect to the network and are not experiencing the same issue
It is not a distance issue as router is 2 meters away from the adapter with nothing in between, the other systems that use the network are much further away.
What I have tried so far: - Changing the channel from "Auto" to a set number
The router is a Belkin N300 Wireless N.

I have an Inspiron 1520 which, approximately once per day, is losing the network connection. Basically I can be right in the middle of something then all of a sudden anything internet related (eg browser, email, skype, other software) stops working, and then a few seconds later the little globe disappears from my network icon at the bottom of my screen.
The only way to get my connection back is to reboot my computer. I've tried the "repair connection" tool, but that doesn't work. I've tried waiting, but that is futile (and impractical)
This happens whether I am directly attached to the router via cable, or I am going through wireless.
Other devices are unaffected at the time. It is only my computer that loses the connection. The two phones, two other laptops, desktop and tablet all remain connected. (Hmmm - I seem to have far too many devices!)
Do I have a failing part? Or is this maybe a software issue? I'm thinking perhaps it is software because after a reboot everything returns to normal and the problem tends to go away for 24 hours or so.

i have had my inspiron 17r since this christmas. however, after about a month of having my computer i noticed something that it did that was very annoying. the wifi connection is randomly lost for about 2 minutes and then re connects. during that time i cannot load any pages or anything. when it first started doing this, it would only happen about once every 2 hours, but it progressively got worse and worse to the point that i cannot even access the internet with it anymore. i boot it up and it has no connection then connects to wifi for 5 seconds and then loses it again. heres the deal though, this only happens with my computer out of all of my family's computers. i have a very good wifi connection because the connection says "good" whenever it does connect, and this problem never happened with my last computer which was a toshiba. i know for a fact it isn't a problem with my home wifi because i have brought my computer on a trip across the country before and it still happened. Dell worker before gave me a link to update some drivers of which i cant remember. this rectify the problem a little for maybe a week or two and then it started doing it again.

dell 1520w-win7 64 bit pro version - installed new hd. Internet connection via wireless losing signal regularly since new hard drive install.."DELL 1520 oem Broadcom Wireless not working. Tested using Win7 onboard system. Says everything was ok. Yet the wireless is not "on" on the 1520 laptop. Purchased a new one; had no OEM software. Purchased Win764 bit Pro version. Installed it; finally found the original OEM resource disk from Dell and installed it. I downloaded a later version of the driver and yet it is not working.Is there a problem created by Win7 installation? How can I wake up the wireless so it can wirelessly receive and send items to my Smart Phone."

I reformatted my HDD (needed to do that anyway) and re-installed Windows 7 and all drivers (Chipset 1st) from my Dell CD after messing up a recovery test.
Everything seemed fine. But now, when I am surfing the Internet, I sometimes lose the connection. The icon in the Taskbar has a yellow exclamation point. (This does not happen in Slackware on the same machine, just in Windows 7.)
The first time this happened, I couldn't ping my router, so I checked all cables, cable modem, and router. But they were all fine and my other (really old desktop running Puppy Linux) was still connected fine and could surf to new web pages.
I did "ipconfig /release" and "ipconfig /renew" on the Dell in Windows 7 and the NIC got the correct IP address and gateway. Now I could ping the router, but I could not ping the Internet, which didn't make any sense, since the other computer was accessing the Internet just fine on the same router! (No IP address confilict exists, and gateway was correct on both machines.) I tried updating the driver, but no new drivers were found. This first time, the issue was resolved by rebooting Windows 7. I also unchecked the setting to turn off the NIC to save power. (I just checked the USB hubs per another post, and it's also unchecked.)
The second time this happened, "ipconfig /renew" failed! I set everything manually (including DNS servers), and on reboot, it still wasn't working. I did a complete shutdown of the computer and startup, now it works again.
So here I am looking for a new driver (64-bit, signed). Not only is there not a new driver...they don't even list the current driver! The only one listed is from March 2010, my driver is June 2011. Current driver is version 7.46.610.2011. Where is there a newer Realtek driver? And why are this things so buggy more than a year after 7 came out, especially if these are supposedly signed by Microsoft?

I have an Acer 7750G, running Windows 7,connected to our home network using a Dynex router. At the moment this is the only laptop in the house that is having problems with connectivity. Starting yesterday, it only connects intermittently. When I run diagnostics, it says the following problems have been fixed but it either solves the problem for a few minutes only or not at all: "Problem with wireless adapter or access point" or "Default gateway is not available".
IPV6 connectivity also shows 'no internet access' and sometimes IPV4 reports no internet. I've unplugged and rebooted the modem and router a few times but that hasn't solved the problem.
Edit: I ran troubleshoot again, and it says the following issue is not fixed: "Wireless Network Connection 2 does not have a valid IP configuration".

I have a problem with my home network (diagram attached below). I sporadically lose connection between my Router and the devices behind the switch. I have replaced the Ethernet cable between the 2 so I don't think the problem's there. It will work for a week or so, then just lose the connection. I then try a combination of rebooting all of the devices on the network and/or unplugging and re-plugging the cable connections and sometimes that works. It's a relatively new router, but can a router be "underpowered" for pushing a signa

I have 2 older xp pro tough books that connect to my domain via a pair of versa vx 400 access points. automobile technicians use these computers to communicate with cars via a separate wireless card and WiFi device (SPX MVXI) that broadcasts a wireless signal.they always connect just fine to the network but sometimes they drop there connection and don't rejoin which screws up my scheduled tasks (nightly upload). They will reacquire the connection every time if i select it again manually in the windows wireless config.here is what I have done so far
1. set up exclusion range in DHCP distribution on my DC
2. set the laptops up with static IP's within the exclusion range.
3. configured the laptops to auto connect to the network even when its not broadcasting
4. set the access points on channel 7, and the devices on 1 and 11.
I have done a lot of research on this issue, a rep from versa told me that Intel proset wireless isn't very compatible with there product which i this is BS since it does the same with with the netgear WiFi PC cards.

I have three computers on my network. Two are wired and one is wireless. I continually run into the probably of getting a limited connection after the computer goes to sleep and I wake it up. I attempt to automatically correct it, but this doesn't work. I try to use the command prompt with ipconfig/release ipconfig/renew and it doesn't work. Then I try to disconnect the adapter and it doesn't work. I also reset the modem and the router with no resolve. Most of the time the only thing that works is restarting the computer. In addition I do use DHCP static addresses for the computers on the network. What is causing this and how do I fixt it without restarting the computer?

Currently using a netgear WG602 wireless router which i use to connect to my 2nd PC and Iphone, with the Netgear router running from my main PC.I have recently been having trouble with my 2nd PC ad Iphone randomly losing connection and the only way for the connection to be reastablished is to reboot the wireless router. Once rebooted i am able to connect again to the internet with no problems, interestingly enough my main PC never loses connection. Also sometimes when i lose my connection and reboot the wireless router i will have a IP conflict pop up on my 2nd PC however i would i say i get this once in every 10 dissconects and not all the time. Sometimes i won't dissconect at all in a day but sometimes i may dissconect 5-6 times.

My company just assumed management of a remote entity. The network has several misconfigurations and I need to make some network modifications from my office w/o losing access or incurring lengthy outage to the clients. The network consists of 1721 router and three 2960 switches.
- I only have access to the router from the Internet. I telnet off the router to the 3 switches.
The site uses a single class C 192.168.1.0 / 24. The router is running RIPv2 even though this is the only network. The prior network person (contractor) set up separate native vlans on each switch and all the ports are defined as Native trunk and access are defined to the VLAN interface assigned to the switch. So of course the logs are flooded with Native VLAN mismatch, Each 2960 switch is a VTP server but has no VTP domain.
basic network layout:
Internet => Eth [Cisco 1721] => Fa 0 192.168.1.254 ==> [SW1]
[SW1]
interface Vlan1
no ip address
no ip route-cache!interface Vlan220ip address 192.168.1.219 255.255.255.0no ip route-cache
[code]....
!interface GigabitEthernet0/1description SW2 Gi0/1switchport access vlan 204switchport trunk native vlan 204!interface GigabitEthernet0/2switchport access vlan 204switchport trunk native vlan 204!interface Vlan1no ip addressno ip route-cache!interface Vlan204ip address 192.168.1.224 255.255.255.0no ip route-cache Normally, I would assign the current 192.168.1.254 to a subinterface to Router Fe 0/0 but with each switch having its own native VLAN I am afraid I will lose connectivity to the downstream switches -- my only access is telnet off the Cisco1721 Router.

We are in the process of upgrading the bandwidth at a few offices. Each currently have a 2xT-1 connection but have high utilization on the circuit which is why they are being upgraded. We are trying to decide b/t either a partial DS3 or metro ethernet connection. Are there pros/cons b/t the two in order to decide which to go with? Cost is not an issue. Some say going with a partial DS3 circuit offers benefits over metro ethernet such as network-based failover, end-to-end availability is better with DS-3 and QoS.

a customer of us asked if C2911 (to be bought) is ok for partial BGP routes.This is the situation: 2 cisco 2911, each peering with 3 other AS (AS1, AS2, AS3), and maybe, in the future, at a small IXP (AS4, AS5, AS6, AS7).They will accept defaults plus partial routes from upstream AS1, AS2, AS3.When deployed at the IXP they also will accept partial routes from AS4-7.So, is 2911 ok for that configuration?the default route is included in the first row of as-path, isn't it?I have no experience with partial routes, only with full (for our datacenter) and default only (for other customers).

We had an interesting situation after an electrical storm moved through where a few of our dual WAN clients didn't have any Internet connectivity. Generally speaking, they are on a wireless broadband and something like DSL/cable/T1. One customer in particular has a cisco 1941 router setup for dual WAN which tested fine during install (pull either connection, external IP changes dynamically and no difference is noticed by user). Well, this storm knocked the wireless broadband out enough that it wasn't usable, but would respond to pings randomly. Because the wireless is the fastest of the two connections it has a higher priority but because it was down but still responded to some pings, the traffic didn't go through the DSL that didn't go down. how to make the dual WAN more reliable in these partial-down situations? I thought about playing with the network service detection (we have a customer on an RV042 who experienced the same problem) but am not real sure what I could change that would make the connection more reliable, especially on the 1941 router.

I have an HP OfficeJet J4500 that works fine with shareport on my Win7 x64 computer. the XP and Win2000 ones both have the same "partial page then lockup" problem. when this happens, the only way to disconnect shareport is to reboot the router. It shows connected to the same computer even if I reboot that computer. I started with V1?? from the install disk then tried 3 and finally 4 with no improvement. I have read several posts about this or similar problems. This is the primary reason I switched routers and bought the D-Link DIR-655, for the print server feature...

The Vista laptop seems to be dropping the connection,when I look at 'Network & Sharing Centre on the Vista laptop, it's telling me signal strength excellent but with a red cross indicating there is a break between me and the internet. HOWEVER, the windows 7 laptop (on it now) is working perfectly OK!!

I recently moved to a new location and my wireless internet disconnects, literally every minute. My roommate never has any issues with his wireless connection, and this is the first time I've had connection issues with this laptop.The provider is Comcast and it runs through a hard wired/wireless modem (no antennas). Our connection is encrypted. My signal strength is always excellent, but still briefly disconnects with a continuous cycle, as it automatically reconnects.

I have att dsl and im using a linksys wireless router and lately my interenet keeps disconnecting. Specifically the little wireless icon in the bottom right of my windows 7 display gets a yellow exclamation mark for about 10-30 seconds then recconects. Its quite annoying and seems to be happening more often now. I have a strange setup on the router, i think its running in bridge mode or something and the modem is doing the actual routing.

My IP lapse time is set for 1 hour and every hour I am losing full connection due to having to sign back into Entrust. I need to be able to lenghten my lapse time on my work computer. My other two personal computers are fine with 1 hour as there is no Entrust on either of those laptops.....is it possible for me to change the lapse time to say 12 hours, 1 weeks, whatever??
