Dell :: 1521 Laptop Has Lost Wi-Fi Range

Nov 12, 2011

The inbuilt wifi card on my 1521 laptop has lost it's range, I now have to be within a few feet of my BT hub or else the wifi signal keeps dropping out, have checked it not the hub by connecting another PC through wifi. I've taken various numbers from the original card but none of them matches up with the part No's on the Dell website, of the three numbers on the card I think the Dell P/No is DP-N OPC559.

Dell Inspiron 1521 Network Adapter Not Starting

Oct 26, 2011

Dell Inspiron 1521 w/Vista Home Premium, wlan dell 1390. Adapter does not start at any time if I don't remove battery for a long period, or a shorter period if I depress the on/off button for 15-20 seconds. Works fine if it starts, but when it does not start it does not appear in Device Manager. If I close the lid (sleep) for even a split second the wifi will not come back on because the adapter is not active. The computer does not wake from sleep normally either, but that's been going on from the beginning and the wlan adapter is a new issue (in a long line of issues with this laptop.)

Dell :: Inspiron 1521 - DW WLAN Network Controller Using More CPU

Jun 13, 2013

I have got this new Dell inspiron 1521 with windows 8 and I am facing some weird problem with its DW WLAN NETWORK CONTROLLER.

it uses more of cpu resources (as seen from task manager) and causes the active window to become non active.

this makes it frustrating to work, means I am typing some username or anything in IE or Chrome or anywhere else and it suddenly becomes non active window (non selected as if some thing else is selected) and again becomes active in few seconds or I have to click anywhere in the window to make it active.

some times a pop up opens that "DW WLAN NETWORK CONTROLLER HAS STOPPED WORKING" send this information to microsoft.

This happens randomly and I'm not able to figure out when this thing occur, means I'm running on battery or power supply.

I have not used wifi on this laptop and I don't have wifi modem. I always use internet through ethernet cable.

One more thing whenever this problem occurs, I stop all the process related to WLAN in task manager and the problem of active-non active window and popup message disappears.

I have tried to uninstall and install the network adapter. also tried latest drivers from dell website.

Dell :: Wireless Connection Could Not Reestablish With 1390 Mini-Card On Inspiron 1521

Apr 21, 2013

For the past few weeks, I have been having trouble maintaining a steady wireless internet connection.  I intermittently lose the connection or the strength of the connection fluctuates.  I have an Inspiron 1521, with a Dell Wireless 1390 Wlan Mini-Card.  Also, I am running Windows 7.

A couple of hours ago, I suddenly lost my wireless connection and could not reestablish it.  I ran the diagnostic tool, which reported that there was a hardware or driver-related problem with my 1390 mini-card.  Now, when I go into Device Manager, it has an exclamation point next to it and it says "This device cannot start (Code 10)".

I have restarted my system and downloaded and installed this driver URL .  Device Manager now says, "Windows has determined the driver software for your device is up to date," but there is still a Code 10 error.

Does this just mean that the card needs to be replaced?  I am not sure what to do now -

Cisco Firewall :: 1521 - ASA Drops Database Connection

Nov 20, 2011

We had Oracle DB servers connected to ip core network clearly, but now we have connected them through ASA (8.4). From that time all users complains about frequent TCP (oracle tcp port 1521) connections drops: they connect to DB, had some time to work and after that expered sessions are stucked. Issue is solved by reconnection, but for some time. I know that the problem is around TCP connection timeouts/ dead connection detection or kind of this. We dan't have MARS system to troubleshoot it by logs. Also, the only inspection policy is applied is default:
policy-map global_policy class inspection_default  inspect dns migrated_dns_map_1   inspect h323 h225   inspect h323 ras   inspect rsh   inspect rtsp   inspect esmtp   inspect skinny    inspect sunrpc   inspect xdmcp   inspect sip    inspect netbios   inspect tftp   inspect ip-options   inspect snmp   inspect icmp   inspect icmp error   inspect ftp !service-policy global_policy global

Use Laptop To Extend Wireless Range?

Oct 27, 2011

I have a couple of computers that are out of range of my router so I came up with a unique solution. I have an old laptop with 2 wireless cards that I put halfway between. It is working but I have a few oddities. First of all, the out of range computer is connected to another wireless router that several laptops and another (wired) PC connect to. It has ICS (Windows XP internet connect sharing) enabled. This rules out using ICS on the laptop as 2 pc's would have the address of

Cisco AAA/Identity/Nac :: 1521 ISE 1.1.1 Firewall Rules Distributed Deployment

Dec 1, 2012

I am struggling in some areas to work out my firewall rules for a distributed deployment. The referenced documentation is not entirely clear in my opinion. In some instances it is easy to work out what ports need to be opened eg Admin node TCP 22,80,443 for management from administrator hosts/ranges. In other instances it difficult to work out eg TCP 1521 Database listener and AQ is this for ISE nodes only or for access devices aswell
My question is whether there is a better document that details these requirements. What rules are meant to be ISE node - ISE node communications and which rules are for access device - ISE, or ISE - access device. One of the rules I am pretty confused about is the PSN CoA ports. SHould the rule be WLC - PSN on 1700 and 3799 or is it the otherway round or unidirectional?
I am pretty sure that the ports are meant to be ISE-ISE in most instances barring the PSN for Radius and CoA.

Using Alfa AWUS036NHR As A Range Extender For Laptop?

Feb 15, 2013

I am a university student and my building is made of concrete so I get pretty spotty wireless (lag at 9000+ ping on games?!). To improve my connection quality I was recommended the Alfa AWUS036NHR USB network adapter [URL]. The adapter itself works marvelously but here's the problem: when I install the adapter, the existing wireless drivers on my laptop fail and I cannot use the internal laptop NIC even when the adapter is unplugged. It says the device is ready but does not detect any networks. When I reinstall the NIC drivers, the adapter doesn't work anymore.Device manager still shows both drivers installed and running but the corresponding NIC/adapter won't detect any networks.

What I have tried:

-Disabling the other driver, reinstalling other driver
-Disabling a functioning driver to attempt to get the other device to work
-Trying different versions of the drivers--a longshot I know

My hardware:

Internal NIC:: Realtek RTL8723A Wireless Lan 802.11n USB 2.0
External adapter: Alfa AWUS036NHR using Realtek RTL8192C USB 802.11B/G/N 300M Wireless NIC drivers for Windows 8
Laptop: Lenovo Yoga 13 (i7 version), no ethernet port available, Windows 8 Pro

can I use both of them (not at the same time) without having to reinstall drivers each and every time I switch?

Lost Wifi Connection On Oem Cheap Mini Laptop

Jun 3, 2011

I am actually able to have fun surfing on the Net with this toy computer, provided I don't expect to watch videos or listen to music or download anything. I bought it for a few Euros in France where it is known as the "SurfOne mini PC Ref. INOS1CE"; I think it is the same as the Chinese "OEM mini laptop netbook". It has a 7" screen, a 2 MB memory and claims to run on Windows CE 6.0.My problem is that after successfully connecting via WiFi to my "Orange Livebox" modem and router for a few days, I then lost that connection and can connect now only by cable.When I turn on WiFi power, it recognizes the "Livebox", but then states that it is not receiving any signal and the connection fails. How to restore WiFi.

Dell 2724 Switches - Low End Vs Mid-range Switch

Apr 27, 2013

whether or nor we would see a performance boost by upgrading our current switches.

Our Setup:
Comcast internet
2 x Dell 2724 switches connected together with a patch cord
Dell server with 6 core CPU

We have about 25 workstations that access the server, which is running a SQL database. The usage is pretty light, so probably only 2 or 3 users would even be active at one time.

We added several networked printers and we ran out of ports on the current 2 switches. So now we need to add in a third Dell 2724, or we were thinking about upgrading to something like a Dell 5548 plus a Dell 5524 or a few Cisco SG300.

I don't think we need any of the advanced features of these switches, but in simple terms, will we recognize a real world performance boost from upgrading?

Dell XPS 420 Lost Wireless After Installed Video Card?

Oct 25, 2011

I am using a Dell XPS 420 computer running Vista. My wireless network has worked fine until now. I had my video/graphics card go bad and installed a new one (ATI Radeon 4350). That fixed the video problem but since then I have not been able to connect to my home wireless network. Windows suggested that I may have a hardware problem with my network adapter so I replaced it with a new Linksys AE 1200 USB adapter. The device manager says it is working properly but it does not pick up the wireless network�says no networks available. The old computer sitting next to it picks up the network fine. I have reinstalled the adapter several times with no effect. When I click on the wireless network icon and ask it to diagnose the problem it says that 1) the network adapter has a driver or hardware problem (device manager says its working properly) and 2) to make sure that the Internet Protocol Bindings are proper and to make sure that Internet Protocol Version 4 and Internet Protocol Version 6 are selected (those two protocols are selected).
