I have Inspiron 1525 with Marvell Yukon 88E8040 PCI-E Fast Ethernet Controller. After reformat, the network will not detect wireless modem after I think I have downloaded all pertinent drivers. In Device Manager, under Other Devices, The Network Controller shows an exclamation mark that under Device Status says, "The drivers for this device are not installed. (Code 28) To reinstall the drivers for this device, click Reinstall Driver." I have turned on the button on the left of the laptop and still missing something.Prior to the reformat everything was working well. I had the Blue Screen of death andthat's the reason for the reformat.

Now, with this ftp there is SSL/TLS encryption added and users behind this ASA can't connect to this FTPS.
It this possible for users behind ASA to connect to FTPSs?

View 1 Replies View RelatedMy Internet will disconnect & then reconnect constantly. I have 2 laptops & they are both on my home network & I have no trouble with the other one so I assume there is nothing wrong with both the Internet service & router. The laptop with the problem is an acer/aspire 5720z. The Wireless Network Adapter is a Atheros AR5007EG. When I go to the Adapter Properties the status reads "The device is working properly". When I go to Control Panel>Network & Sharing Center my Wireless Network Connection Signal Strength reads Excellent. The operating system is Windows Vista Home Premium.

I don't get the "your network cable has been unplugged" message, it just stops working for a second or two and starts working again. This has been happening for a few months after a fresh install of windows xp and I haven't really tried to fix it.Every other computer in the house is fine except this one, it can't be the modem because a new one was installed a few days ago and its the same problem. The router was reset within the last week as well. I think the problem is with this computer alone but I don't know where to look. The problem didn't happen for a few days after I put a new network card in, but soon after it continued happening. I also have tried a few different CAT5 cables, even the XBOX one but nothing resolved the issue.

View 1 Replies View RelatedEvery two or three days I'm unable to reconnect to my wifi network when I turn on my Windows 7 laptop or Android tablet. I have to power cycle the wifi router to get the connection again. This usually happens after I haven't used either device for a day or two. The connection usually does not drop when I'm using them. Restarting the computer or the tablet does not work and using the Windows troubleshooter (or the android app for wifi issues on the tablet) also doesn't work. Both computer and tablet recognize the network and say the signal is strong but won’t connect to it. There are no physical obstructions. I have no problem with my internet connection (cable modem). The problem really seems to be with the wifi router.

-1x Cisco ASA5540
-1x Catalyst 3750x-48T (L3 Core Switch)
Id like to seek expertise on validating a simple firewall setup.
Do i trunk core switch traffic to the cisco ASA OR assign L3 link instead? It is basic understanding that the Cisco ASA is usually use for protection from our internet zone.A typical Cisco ASA setup would consist of outside, inside, dmz zone.
L3 core switch consist of 20 VLANS20 vlan needs to be blocked from each other. Eg Wireless Vlan does not have access to Server Vlan etc etc.
what is the best practise to filter ip address within vlan from reaching each other.Should i trunk all my vlan to the Cisco firewall? (For easy vlan restrictions: but is that best practise?)Or do ACL on the core switch itself? but what if i have tons of servers ip that needs specific ports blocking or etc.How would i be able to manage all my ACL on the core switch.
We have ASA 5540. We setup Site-to-Site VPN and Remote Access VPN (Cisco VPN client). If are running full tunnel on the Cisco VPN client, the internet access is slow. For example, when we are running full-tunnel, the internet speed is 16 Mbps based on Speedtest.net. When we go to Speedtest.net, some of the graphics do not load. If we are running Split-tunnel, the internet access speed is 78 Mbps based on Speedtest.net and the Speedtest.net web site loads all the graphics.
View 6 Replies View RelatedI have a 5540, and i am trying to allow access to internet for an specific network object group, who has inside a bunch of users, who needs direct internet access without any restrictions, i have tried with dynamic NAT, but that configuration ask for a specific IP o a Network range, and is not permitted to configure an object group as a source
The group is located in LAN zone, so a permission from one zone to another zone is needed i think, but i can allow the internet acess to that group Is there another way to get that , different from NAT ?
I have a remote ASA 5505 running 8.3(2) that establishes a site to site VPN to a central ASA 5520 running 8.4(2) immediately upon startup. Then within a random interval ranging from 5 seconds to an hour, the VPN loses the connection, and is not reconnected. Only a reload of the remote ASA will reestablish the VPN tunnel. Then everything is fine until the next disconnection. Both sides have matching lifetimes, and keep alives are enabled on both sides. The debug from the remote ASA is attached, showing what happens through several disconnect/reload sessions.

When I connect to the exchange server by using Cisco VPN, microsoft outlook display warning "microsoft try to reconnect ... " many times, at that time I cannot send or receive email, it failed. The VPN still connected so I don't know why? At first I think the problem from MTU so I decrease the MTU but the problem still happens.

1. Update router firmware
2. Network initially had split up so each floor router was a DHCP server now only 1 DHCP server.
3. Test with different security WPA/WPA2 and No security.
4. Connect to different wireless router.
5. Try Apple's Airport but doesnt work in corporate enviornment(couldnt even get it working at home)
6. Try adjusting screen brightness (not in a million years is this a fix!!).
7. Static Addressing not an option as too many devices and it is not a fix.
I am in a third world country (Thailand) with ADSL service and getting customer support is difficult to say the least.The connection is constantly dropping but the real problem lies in that i can not reconnect unless i restart my computer.

View 1 Replies View RelatedI have a WLC 5508 in my datacenter, and 1142s configured with FlexConnect at a remote site.Two issues:Some APs 'die' from time to time where I cannot ping them anymore and they do not service any clients. I can reset them from the WLC after which they work again. I have some clients in the building (same area) who lose connectivity from time to time and are unable to reconnect to the wireless. I am seeing errors that the gateway cannot be found or there is not a valid IP. restarting the AP closest to the clients fixes the issue. I have replaced the AP and connected to a different port on the switch.
View 6 Replies View RelatedI am working with a small off that has a 5505 acting as a basic firewall. Behind it are off-the-shelf unmanaged switches. Two users have to work with an outside vendor and are having issues. They have a Sonicwall remote VPN client on each of their desktops and use this to connect to the vendor. They then RDP into VMWare-based Windows 7 desktops at the vendor's site to do their work. Randomly throughout the day (6-10 times per day) while they are actively working the RDP session will disconnect. It will auto-reconnect after a few seconds. The VPN log on the clients never show any issues. I believe this is an RDP problem because while the RDP session is disconnecting, their VPN client is not (it is set to NOT auto-reconnect if it gets disconnected so that I will know for sure if it gets disconnected). I don't see anything in the ASA's logs about denying connections involving their PCs and the remote VPN peer IP.
View 7 Replies View RelatedI have a new 881 router and am simply trying to change the ip address from the default 10.10.10.1 to 192.168.15.1
I tried doing this both in the CCP Express app loaded on the router, and also using the desktop CCP client. I can change other parameters without any problems, but when I change the ip address of the vlan the program hangs (as expected since the ip address should be changing). I then try to open it back up and reconnect but get no response from the router.
I can ping it no problem, and the http server is running according to the serial terminal.
I used to have ATT DSL but we recently switched to U-Verse. I have a Trendnet TEW-452BRP 54g wireless router than was handling the PPPoE function. It was set to work flawlessly with my wireless cards. No dropped connections, speed or security issues. It always connected quickly from wake up and on start up. Now we have a 2Wire i38HG wireless router/gateway and it's been difficult to properly set my network up as before. I use the Trendnet behind the 2Wire as my wireless router. Took me a while to figure out what to do, but DHCP is disabled on Trendnet so 2Wire does what it needs to. This option works fine for me. The only problem is that at first my wireless card would not automatically connect to the network through the Trendnet when it is in range like I had it set to do previously. When I would force it to, after 3 times it would magically connect on it's own. I made some changes in the Trendnet (Mainly disabling dynamic DNS and NAT) and that seems to have made a difference. To be honest, I don't know if that is significant or not or if it actually made a longterm difference but it seems like it has. So my problem is now that when I put my laptop to sleep and have it wake up, it does not automatically reconnect. It takes about 2 minutes then it does on its own. I read the event viewer and this is the info it gave me - Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 0x0018DE0682D8. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
Level - Warning
OpCode - IpLeaseRenewalFailed
Source - Dhcp-Client
Then after 2 minutes -
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x0018DE0682D8. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
Level - Error
OpCode - IpAddressNotAssigned
Source - Dhcp-Client
After this, it connects by itself. I don't believe I have configured the 2Wire or Trendnet properly, so I need some guidance and suggestions on this matter.

I work for a small company and we just brought in a Juniper EX4200 switch so that we are able to test our SFP's and XFP's. I went through the EZSetup process however when I try to re-connect afterwards it just tells me that my subnet for the switch is different then the PC. I have tried assigning a static IP but that is not working for me either

View 3 Replies View RelatedI'm using two WRV210 Linksys Cisco Routers to create a tunnel between two places with a pppoe adsl internet connection.I made several tests with new 2.xxx and old 1.7xx firmware, and nothing changes.Try to reset to factory defaults, and nothing changes.I have two problems:
1) The router crashes after a time working, usualy around 24 hours, sometimes more, sometimes less. The lights still flashing, but nothing happens, no VPN traffic and no ping response from the router, and of course, no internet access. I could see just that the router works a bit hot, but, I think that is normal.
2) The VPN IPSEC was configured, and both configurations are identical. All value are the same, I am using the dyndns service. So, the VPN quickly connects and I can ping and access remote computers. Windows Folders, VNC, IT'S REALLY WORKS FULL. WORKS REALLY FINE. PERFECT.
BUT, when the router crashes, as I've told on problem 01, after remove the power cord and insert ir again, the VPN don't reconnect.On log's, I could see that it's say that has no preshared key. [code] But, it worked before. Nothing changes, nothing, the router just restarts. No configuration was lost, (I checked the VPN IPSEC TAB), but says that have no preshared key,The unique way to restablish the connection is go on the VPN IPSEC TAB, and change symetrical any configuration, as change MAIN MODE to AGGRESSIVE on both routers.So, now are as MAIN. Tomorow probably it will crash, so, I will have to restart both routers, and change to AGGRESSIVE. So, when it happens again, i will have to back to MAIN.
We have a WAP4410N wireless ap configured for WPA2-Enterprise. Initially everything works. Issue the user the proper certificate and they sign on correctly but once they disconnect and try to reconnect later it get stuck on "Validating Identity". The request never get to RADIUS server (no success/failure log entry, no radius traffic). Once I reboot the access point everyone can connect again but as soon as they disconnect the problem happen again.We testing other security settings (WPA-ENT, RADIUS(!), WPA2-Personal etc) and no problems. With older firmware have the same issue.Operating system: XP SP3, RADIUS server: IAS. Firmware: 2.0.1.0
