Apr 7, 2011
They are all on the same domain but some of these users are getting dropped from the Internet, and email. Once they restart there PC it works for a couple of hours than it drops again. We also tried updating the network driver after doing that it works ok for a couple of hours after that they start lossing connection to the Internet and email again. We have tried several different things but have not being succesful in finding the issue.

We just upgraded from 8.2.4 to 8.2.5.20 on each firewall. The Primary and Secondary work when they are standalone but, when we connect the fail over link from the Primary to the Secondary, invariably, one of them will go into a constant boot cycle and one will be active but, external users will be intermittently dropped. As soon as we unplug the fail over, the firewall that stays up behaves normally. This is with 8.2.5.20 code or any other code for that matter?

I have a issue that i am at a loss as how to solve it. I have an ASA 5505 as my firewall. I have users from other companies who visit from time to time and are unable to use their outlook email to send messages. They can however receive messages without a problem. I also have a situation where users who use windows live to access gmail are unable to send messages.
I have narrowed it down to the fact that these uses are using ssl/tls to send the mails. I did some research and found out about the inspect esmtp setting in the ASA. I have disabled it and i still have to problem. I have also removed all outbound deny statements and still no luck.
Of note is that i can send emails without attachments. They take a long time to go out ( from minutes to hours) but eventually they do. Emails with attachments of even 10k do not go at all.
I was running image 8.2.3 and i downgraded to 8.0.5...still did not work...i upgraded to 8.4.3...still did not work. I am now back at 8.2.3.
My Firewall config is attached. I am at my wits end as to what else to try. The company has not renewed support for the device so i am on my own here!

I have a question about NAT behavior on FWSM 4.0. The problem is email server (Company A) cannot connect to email gateway (Company B) on the outside network and it randomly happen. I got this error from server guy "Detail: xlate has blocked the connection between A’s mail gateway and B’s mail gateway". It work fine again after clear xlate on firewall. [code]
1. How FWSM create xlate table like that? I mean it look like NAT0 for 158.137.21.26 but it doesn't has any nat rule for 158.137.21.26 on firewall.
2. What does it mean "connections 24" at the first of line? In the normal time, I only see the connections is 0 like the second line of xlate
3. After clear xlate global 158.137.21.26, the first line of xlate table is gone then email server can connect each other. Does is a bug on FWSM? or This is a normal NAT behavior of FWSM.

A few days ago I sent my ISP an email and a few days later they called my house and talked to my mom about the support issues I had addressed with slow speeds. They directed her to www.att.com/speedtest and our internet speed was reading 6MB/s down and 512kb/upload as it should be.The problem is, outside that test I am not seeing the performance. Let me put it to you like this, right now the internet is so slow that Speedtest.net consistently gets errors when trying to connect for a test. Any website that isnt text based like say Reddit, takes ages to load. Youtube videos? Streams? Forget about those, 240p buffers as slow as 720p.When I finally manage to get Speedtest.net to do a test after numerous internet resets I barely crack 1MB/s down IF AT ALL, and .12kb/s upload IF AT ALL.
Its maddening. Its actually affecting my siblings college work as their online tests have been failed due to disconnecting.Something I should have mentioned earlier is that I do have a router. Its a Linksys WRT54GS with the latest firmware. Something that is also annoying is that when I plug my internet directly into my computer, it wont work, but if its plugged through the router it works just fine. This has never happened and its making me draw a blank.AT&T support suggested the we upgrade our Modem to one of the newer ones that are a modem/wireless router combo which we plan on doing. Right now we have a Speed stream 4100 that weve had since we got the internet in 2006 and I guess they don't even make them anymore.

2 days ago I turned on my pc, went off to the internet and boom. It's slow. I thought that maybe its about my provider. No it's still slow. Weirdest thing is that my torrent dl speed is still about 100kbps. But when i want to download something with my browser(s), speed is just about 20kbps. And surfing on the internet is slow too. I'm using windows 7 32-bit. And i use wired connection. And since I have XP installed aswell, I tried the internet there. I was having no problems with it there. But I use win 7 and I need this problem fixed. I have even scanned my pc for viruses. Nothing.

I have a Dell Latitude d810 laptop that has XP Professional and an Intel PRO/Wireless 2200BG driver. It has been working fine for nearly 3 years. Recently I changed it from a domain to a workgroup and now the internet connection drops after about 5 - 10 minutes.When I say "drops", I am referring to the browser can no longer display the webpage. The internet connection still shows to be "Excellent". I even tried pinging www.google.com and it can still ping the website but the browser just stops working. I have tried Firefox and IE.I updated the DNS to use the default primary DNS suffix. The only way to get the browser to re-establish a connection is by rebooting the laptop.[CODE]

where my internet dropped alot while playing ps3.i switched from my horrible d-link router to a DIR-655 Since i bought it, i've never dropped but my connection speed is an issue when playing my ps3.I use a wired connection through my router.some periods during the day it's 2 mbps download.. that's really slow considering my computer has 20 mbps download through wired connection.some periods during the day it runs fine @ 4 mbps - 5 mbps download (this is fine for gameplay but it lags a bit)if i directly connect my modem to my ps3 - it goes 20 mbps download (amazing fast speed)I called d-link technical support and did everything from port forwarding to turning on DMZ and putting my ps3 IP in there. I have a 2 part question: is there anything i can do to boost my ps3 connection download speed as high as it would be if it was connected straight to my modem while using a wired connection to my router? if that's not possible, is there anyway i can keep a stable download speed @ 5mbps?

Despite all the drama regarding the DIR-615, I've had the B2 revision since around late 2008 or early 2009 (can't remember exactly, most likely late 2008) and it had been working flawlessly. And I do mean that. I never once had a problem with this router and highly recommended it. Back then I was on a 24/1 connection, and had been up until recently.
Now I'm on a 100/10 line, and things haven't been looking too great. The internet is stable for the most part, and I am getting full speed, but the router has been starting to drop its connection a lot. I've had to release -> renew (or simply restart the router) quite often now and it seems to be happening at complete random.
weaking with settings, updating firmware, etc but no luck. All connections in question are of course wired, not wireless.

yesterday at 6:30 am my internet was working fine.yesterday at 7am it quits working.the computers through the house are 2 desktop PC's, one netbook, and one laptop.the 2 pc's connect to the router via a switch.the netbook and laptop use the wireless router.the wireless router is not specifically just a wireless router, it goes both ways (hardline and wireless)after 7am, the netbook still had connectivity to the internet via wireless even though my laptop did not.the internet is still connected to all of them, browsers like google chrome, firefox, and IE7 do not work. but just like a browser, steam's store will not load.here's the funny part, the netbook still had browsing ability until 7pm last night.we checked all the ip's and MAC addresses on the computers to make sure nothing was conflicting.nothing was.packets were coming in and out at normal rate but none of our browsers worked.we do have comcast, and my father told me that comcast gives you norton for free for using them.i have read on here that removing norton magically solves the problem but 3 of the 4 computers does not run norton. and i also do not see the logic behind this.we have also recieved emails from comcast exclaiming that they have reports of "bot emails" coming from our I.P.'s could this have been an attack on our network or some network virus?

I've been having a number of issues with performance on my DIR-655 with streaming media, internet connection being dropped and random reboots. Over the last couple of weeks it has been getting worse, to the point where I'm about to act out the printer scene from Office Space but with my DIR-655! It has been rebooting, completely killing WiFi networks and Internet Connection, almost every 20 minutes when I'm watching DivX over the network. The relevent information about my network is as follows:
-Hardware:
-D-Link DIR-655
-Hardware Version: A3 (US) , Firmware Version: 1.34NA
As an experiment I reconfigured the DSL-380T into PPPOE mode and set the DIR-655 into DHCP Client. This was over 2 hrs ago. So far - no random reboots, no jittering on the Media Center Extender playing videos, no internet drop outs..It seems to me that the DIR-655 doesn't cope well when it has to do the PPPOE network protocol as well as the routing, WiFi and other basic functionality that it should be able to cope with.I'll leave it running as it now is and report back later, but from the dramatic change in behavior I'm hoping that I've finally cracked my perf issues with the DIR-655.

I recently purchased an Aztech wireless-n repeater #WL556E to increase my signal strength on my patio. I followed the instructions step by step and it works for about an hour and then stops. This is on my Apple iPad first generation. If I restart my iPad it works for an hour or so and quits. I have the repeater about 7 feet up on a shelf.my wife has the identical iPad as mine and hers works fine on the repeater.

I've had this router for about 3 weeks. It's only 20 feet from the computer, but my computer on 2 or 3 separate days had trouble staying connected. The signal dropped to 5 Mbps and had a little yellow symbol that said no internet access and when I looked at the properties it said, "limited or no connectivity." I got impatient and purchased a 75 ft Ethernet cable online with plans to possibly return the router as I don't really need wireless anyways and since I spent $100 on this router I expect it to work at 20 ft distance.
For the last few days it has remained at 54 Mbps or more sometimes all the way up to 108 mbps. But now since it got pretty low a few times I don't trust it enough so I might return it anyways.IPv6 connectivity says no network access. This might be because when it asked for administrator password to recognize it as a trusted home network I closed it instead of putting in the password.

I use campground WIFI systems to get internet/email but some wifi systems have limited range.I solved this problem with a booster antenna but that means I am hard wired to it. I want to (if possible) to get the wifi signal to a bridge then send it to a router so that I can use my lap top, printer and other devices in my 5th wheel wirelessly. I looked at a suggested system that uses a point-to-point antenna that feeds a bridge, that feeds a router. I don't want to use the point-to-point antenna.My booster antenna is a USB feed.

my neighbor is having a problem with her computer, its an HP touch smart [not sure of model] every other computer in her household works [1x wired 1x wireless].
the computer in question has had repeated problems and various hardware issues and has been sent out for repair on more than one occasion all for non software related issues, i take care of software issues and diagnose hardware problems and i have done so without a hitch until now.
when the problem first started happening i would do a system restore to a point were it was working, but that does not seem to be working anymore
i have tried disabling firewalls [she uses AVG internet security edition which is on all of her computers], windows firewall, disabling and re-enabling network drivers, updating drivers, installing different and previous versions of browsers

I have 5508 controller in my lab. I am working on a project to set up a public internet but with some condition.
- User should able to connect to the SSID without any authentication.
- Once user will connec to the SSID it should redirect to an external URL which indicates terms and condition and email address field.
- User should enter his/her email address in email addrss filed and click I accept button.
- Once that is done then he/she is allowed to access internet.
We are not sure how can we achive this as I do not know what should be the return value for WLC to allow that user to go through or what should be the settings on the WLC to redirect to the page.
I have seen a settings on web authentication for external URL but I guess it is only for username passwor or Radius authentication. While in this case I do not want to use any authentication just an accept buttor or Decline button and all good to go.

I want to be able to use a cable to connect to net on my desktop while allowing my bro to connect to net on his laptop through the wi-fi. Right now, we have to disconnect from the net on one to be able to connect on the other. Is there a way to do so without disconnecting?

got myself the Netgear internal PCI wifi adapter today & it works just fine on my Windows XP SP3 desktop.
The only problem I have is the question of restricting access to kids @ home. If it was an external USB adapter, I could have just taken it away but the concern is the device being an internal & always available one. The user configuration on the PC is such that there is 1 main administrator (The actual windows "administrator" account) that no one uses. Apart from that,
- 1 user with admin privileges (me)
- 1 limited account for the kid
- 1 admin privilege account for the kid again (for purposes like installation of games which require an admin account as mandatory)
I would like for the wifi PCI card to work only when I login to my account. There must be someway by which I could disable the device or make the internet inaccesible in the other accounts,, (but pls bear that 1 of the account that the kid uses also has admin privilege)
I tried disabling the device from control panel but in vain.. (tried something like the sys admins do in corporates ..) disabling the usb ports on the PC's in my office..!

I live in a house with 5 other students. To be fair, it is in the middle of nowhere so the internet is probably very slow anyway, but here is my problem: Skype is so slow I can only just make a voice call, webcam chat is off the cards. YouTube and other videos are so slow to load I cannot watch them. My Xbox 360 constantly disconnects from the wireless, so I cannot play online.

restricting access to internet for roughly 20 users. Right now we are connected using broadbandand using dhcp as assigned by common switch. All pc's are in a common workgroup. recommend me the hardware / software required to restrict this access.
1. Will I require a router as well as a switch ? or should I simply get a new switch ( for more then 20 users ) This would mean static ip for all users.
2. My idea is to create a AD server and use websense on it so that users who require internet access can still open internet sites but will be restricted through websense proxy.

Bought a Dir-600 from challenger, used it for 3 months and started expericing the common problems of loosing internet connection highlighted by many users here and in other forums. Would always have to do a modem / router power cycle to get it going again.Slightly after 3 months... the thing went dead. Can power up but no response. Cannot detect the modem.Got a one-for-one exchange at Funan. Used the 2nd one for less than 2 months. It just went dead on me! Same problem...

The goal is to add a 2801 router between a DSL modem and a switch and obviously still access the internet. I connected and configured as explained below and the results are:
- I am able to ping internet addresses from the 2801 router
- I am not able to ping internet addresses from userlaptop but I am able to ping LAN gateway (192.168.254.254)
I cannot understand why the internet requests from the user laptopuser are not routed to the internet but the router itself can access the internet.
INTERNET====DSLmodem=====CISCO2801=====unmanagedSwitch=====userlaptop
DSLmodem:
non-bridged mode and does the PPPOe authentication.
WAN interface: Dynamic IP address assigned by ISP

I have web server setting behind the Linksys ADSL modem, I set the DMZ IP to my web server IP so the external internet users can access my web pages.
This setup was working fine until I switched to “Linksys X3000” modem, external internet user can no more access my web pages.I had set the DMZ IP correctly in the new modem. The local LAN users can access the pages without any problem.

We've got Workgroup LAN at our office and the Server is configured by the OS “Windows Server 2008 R2”. Most of the users use OS Windows XP-Service Pack-2. Now, I want to see the Internet surfing status/activities done by any particular user/users at any time from the Server. You know that, some people enter into restricted sites which impose severe negative impact on the network. If I could trace from the Server any user of doing this, I shall block his Internet connection from the Server.

If there is something that cant control the bandwidth of our internet.
The problem is that one person is constantly hogging our internet by downloading and such and making it impossible to play games.

I have configured and tested an ASA-5505 that will be deployed at a customer's home. The ISP cable modem will connect to the E0 (outside) interface of the ASA. All other interfaces on the ASA are configured for the inside network 192.168.5.0/24. I have created a VPN site-to-site tunnel between this ASA and the UC540 to allow 192.168.5.0/24 subnet access to the internal networks on the UC540.
The user has requested that all the network devices used by the rest of the family will only need to connect to the Internet. They will not need access to the VPN tunnel and they will not need access to the computers on the 192.168.5.0/24 inside network. I was planning on performing the following tasks to get this to work.

I'm currently undergoing CCNa academy so I got a "job" from my boss to configure Cisco 871 router. Unfortunately we just finished first semester at academy so there are some things that I'm still having hard time to understand. I managed to configure router so it connect to internet or to be exact it has internet access through another adsl modem that is in bridge mode. url...The problem is that users are not able to use internet when connected to this router. I'm able to access router through telnet ( ip 192.168.13.10) but that's it.192.168.13.0 255.255.255.128 is network that we use at work. 192.168.13.5 is IP address that is assigned to zyxel adsl modem ( If I'm correct, we could have used any address here since we are connecting this directly to router ? ) Zyxel adsl modem is connected to FA4 port on Cisco router. LAN cable is connected to FA0 port and from there it goes to switch ( it's some asus switch with 50 ports). [code]
If I ping google dns from router e.g. ping 8.8.8.8 it works. If I ping url... it doesn't work. Also I'm able to access router via 192.168.13.10 but if I use router as default gateway then I'm not able to access the internet.
