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:
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.
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 -
I am having a problem with a ASA 5505. The users on the inside cannot access internet for the most of the time. When i looked over the configuration and tried a few changes i got out to internet about 5 seconds every 30 minute or so. Very strange. When i try to access internet i just get the windows post that DNS is not working properly. As you can see in my config i get all addresses dynamic from ISP.
I am not sure what to do next, i tried to set static routes, make Nat changes, static dns addresses, searching this forum but nothing works. It seems like there is a ISP problem but i have talked to the support twice today and they say that all is fine from their side. Does ASA behave like this?
I just recently purchased a Cisco ASA 5505 ASA ver 8.2. I run a teamspeak server/ssh/dns and domain on the same server on the network. Before I switched to the asa, I have a regular DGL-4100 that ran with no issues. I have noticed that the connections are very unstable and disconnect frequently and when they do they take 1 to 5 minutes to be able to reconnect. I have done some cisco IOS but am fairly new to this. [code]
We're currently PATing everything from a particular subnet to the IP of an outside interface using our ASA5585 (dynamic PAT). We're experiencing pool exhaustion and therefore need to expand the global IP range. Any way of cutting over to the new range without dropping existing connections? For clarity, the current interface address is x.x.x.37/22 and the new PAT pool is x.x.x.114-6/22.
Work connection will load database about a third of the way then crash laptop. I can change out the router from the new Cisco e3000 to an old wireless router and it works fine.
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 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.)
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.
I have an Inspiron 1521 and while I can find and connect to a network easily and quickly; it takes 5 minutes or so for it to really work. My icon says it's "identifying the network". Is there anything I can do to speed up this process?
just found your site poking around for some information. I'm pretty green with routing and firewalling so I'm hoping someone can point me in the right direction.I'm trying to setup a remote access VPN for the off site employees we have. I would eventually like to have this setup to use either the cisco VPN client or the webVPN option, but this question is about my VPN client setup.I'm using a Cisco ASA 5505 at the head end and the Cisco VPN client 5.0.06.0160 on the client side.In the logs the client authenticates, grabs an IP, DNS and domain info and then drops the connection.
I've been having this problem on and off for a few years but never this frequent as of now.My connection randomly drops out and I have to disconnect cable from my modem and reconnect it and reboot and stuff like that to get it back up. Sometime even connection just drops and connects right back.Now I'm almost confident its the modem's fault, I have recently replaced the modem and the router
My DIR-655 randomly drops its connection. All devices on the network behave as though the network is not available, then again sees the network, and reconnects (all devices being two laptops, three smartphones, and a PS3...same symptoms). My modem does not have any problems, and I have tried resetting the router, but it has not worked.
My connection drops whenever it is under load. Anything can make it drop, from 2 youtube videos playing the same time to downloading something from steam. Im using wifi and I have tried a lot of things in case something interferes like changing channels. My signal strength is great and my isp and speed is fine and my connection is 54mbps. What is kind of weird is that my wifi doesnt disconnect it just stops transmitting data and the only way to fix it is to reset the router or unplug and replug my usb wifi adapter. I downloaded the wireless tool from this website, since my windows language(Windows XP) is in greek so is the reg file and some characters are just weird symbols. To Kedar:Unfortunately, no its impossible to change the language of your OS ive tried it before, the only way is to buy the English version and reinstall windows.
We have 7 computers, only 2 are hardwired, and a wireless modem (gateway) with a 6 port hub attached for the wired pc's. My son's pc is wireless, and every day when he goes to get on it for school (he's homeschooled through a virtual academy), the LAN icon, instead of bars, has the yellow dot on it indicating connection. He has to reconnect every day, and sometimes even throughout the day if he leaves the computer long enough (such as when the monitor goes off, there is no screensaver). How do I fix it (Windows 7) to where his pc will stay connected and not disconnect when the pc hibernates?
We have a 4410N that all the time drops the connetion. We have approx 25-30 users using wireless. But when they try to connect or are connected, the router drops the connection like a yo-yo. The firmware is updated with no difference.
The wireless connection is very unstable. It's configured with WPA2 Personal and is connected through a POE-switch with IPv4. The logs don't answer the questions why it drops the connection.
I am using a desktop computer and have the router downstairs so I am using a wireless usb to connect to the internet. My router is a Linksys E1000 and the wireless adapter is a Netgear WG111v2. The problem is Every few mins I drop connection for may 5-30 secs and then the internet is fine. During that time it does not say I only have local connection or anything like that it constantly says I have internet connection even when I dont. It is very noticable when i am playing an online game on my computer. I will get a few mins in and then it will drop kicking me out of the game and by the time I get kicked out my Internet is reconnected and I can join again.
My router drops my internet connection at least once a day. When the router does this, my wireless network connection disappears from the network list. I have to disconnect router from plug and plug it back in to work again. If I hard-wire laptop to router or modem, I still do not get internet unless I unplug and re-plug router.
I have a dual boot pc. plus wireless adaptor wpn111 (v3 drivers)either XP pro or windows 7 platforms.when usiing any app to download any torrent file, pc drops internet connection on windows 7 but does not if i download via XP pro?initally download goes very fast then drops connection and i have to disconnect the wireless adaptor?
This issue has been going on for a few weeks now, i will be using the internet and it will suddenly drop out. My computer is connected to my router, this connection is fine it is just the INTERNET connection that drops out. When this happens all of the computers on the network are affected.
I recently bought a new HP Pavilion dv6 Notebook PC and have been experiencing problems when connecting to my personal wireless network. It seems that whenever I'm downloading anything or using the connection extensively I'll lose internet connection and the wireless icon in the bottom right hand corner of the screen will show an orange star to indicate that connections are available. However if I go to available networks I can immediately reconnect to the network I was on.
I have other notebooks that run on XP that do not have this issue and use the connection without a problem. Also when I connect my notebook directly to my belkin router via Ethernet cable the connection has issues. I'm running my computer on Windows 7 Home Premium 64-bit and my Wireless adapter is an Atheros AR9285 802.11b/g/n Wifi adapter which appears to have up to date drivers.
I already have an existing wireless network set up. Since buying a laptop the internet wireless connection drops out from the laptop after 'sleeping'. I then have to troubleshoot to get the connection back again.
Just starting a couple of days ago my internet started dropping about every 10-20 minutes. The problem is only with this computer. I have a laptop right next to me and it works fine no problem and two other PCs that don't have any issues so I don't think it is the router. I have scanned my computer with different antivirus software and it's clean. The computer is always connected with a full 5 bars and says it has internet access but sometimes it drops and in order to get it up and running again I unplug the wireless adapter and plug it in again. At first I thought it might have been the adapter so I swapped it out for a new one and I'm still having the same problems. My wireless is unencrypted. This keeps happening over and over again and I am stumped on what to do.

My second computer on my network randomly drops out all the time. I have a WRT54G router that is working fine with my first computer (Windows 7) but the second computer (Windows XP) is having issues. It'll be running completely fine and you can even get on the internet after it's been on for a few hours but after a few minutes on the internet (10min about) it drops out completely and can't reconnect.
My wired/wireless internet connection drops every 15-20 minutes for a few seconds at a time. I have a Cisco Linksys E2500 which is bridged to a actiontec mi424wr router (Verizon Fios router). My fiance's computer is wired while my laptop is wireless.When I originally set up the network I had 2 mi424wr bridged together but it dropped very frequently. Switching the router and upgrading the firmware has made in happen less but it is still frequent enough to warrant trouble.
Network connection speeds drops from 1 Gb/s down to 10 Mb/s..Tried forcing the PC to communicate at 1 Gb/S "Link Speed & Duplex".Tried reinstalling drivers
I have a DIR-615, hardware version: C1, firmware version 3.12NA and my issue is that it keeps dropping my VPN connection after 12 minutes. Sometimes it'll go longer than 12 minutes but on average right at 12 minutes of my connection, it drops. This happens whether I'm using the wireless or hard wired to the router. As a test, I ran a continuous ping on a computer on my internal network and also to a computer on my corporate network. When I'm VPN'd in, both pings are successful. Once the router kills my VPN session, the pings to my internal network are successful. So the router isn't rebooting or anything like that. My VPN session will automatically reconnect, but I'm stumped.
So I've bought a D-Link 815 on 21st June(day before yesterday) and my connection drops every 10-12 hours and i have to close and open the router(the 192.168.0.1 site won't even work)...i'm using PPPOE connection..
I've bought a D-Link because i heard it's the best on the market and i play online poker so i need a stable connection all day long and more important i need my IP to remain at one value for a long time and not change every 12 hours(i have dynamic IP)
