PPTP connection dropped every 120 mins

Hi guys,
I am using a pptp server running on windows 2008 server and I have configured my ASA 5520 to let the PPTP traffic to pass throught.
The solution works quite well but exactly every 120 minutes the connection drops and people have to reconnect. Is there any setting to change? In the PPTP server I haven't found any setting to change.
Thanks,
Dario

Hi Jennifer,
I have the following timeouts on my config. None of them sounds to me like a pptp timeout... :-(
arp timeout 14400
timeout xlate 3:00:00

(INTERNAL-DC1 is the PPTP server).

Network connection drops every 15 mins

Hi all,
i'm loosing network access on my iMac. This has started tonight, I had never had any problem before. My iMac is connected through Ethernet interface to a switch, then access to a router and finally to the modem cable. I have several other computers on this home network, all of them working properly and accessing to Internet without any problem.
Only the iMac is behaving strangely, and only since a few hours.
When the problem occurs, everything seems normal : LEDs are on on the switch, ifconfig -a gives a normal report (interface up, IP address ok within network range (no APIPA), netstat -rn OK), and i have no entry in system. log or whatsoever. But I can't nervertheless access to any Internet site, nor can I even ping my defaut router.
I began to "solve" the problem by rebooting the mac, then found that, when the problem occurs, I can solve it by going to Network preferences, advanced options, TCP/IP tab and press the "renew DHCP lease". Then everything works fine for 15 minutes, and I have to renew this operation.
The strange thing is that I used the iMac this morning and it was working fine. When I switched it on again tonight, the problem appeared .... Nothing changed, execpt one thing (but I can't find any connection) : the World of Warcraft laucher has been updated this morning ! But I can not imagine that this might generate trouble on the TCP/IP stack of Mac OS X !!!!
When the network connection is lost, all traffic is stopped, not only HTTP. If I'm for example playing WoW, I loose the connection to the game servers. Renewing the DHCP lease fixes the problem if done quickly enough.
I know I never had this problem before, as I'm connected to WoW almost every day and could so far play without any problem for (sometimes) hours.
I've seen some posts describing more or less the same behavior, but no answers so far. Surprisingly, many of them reports problems occuring every 15 mins.
Any idea ?
Thanks.

Hello,
I've found a workaround : I've switched my TCP/IP config to static IP address and everything is working fine so far.
Hope this helps.

Did you try upgrading them to the latest (1 week ago released) firmware update 1.1.0.4?

FRUSTRATING!! 4 month 27" iMac. WIFI drops every few mins.

I have a 4 month 27" Intel iMac. The WiFi connection drop every few minutes.
I called up phone support and they told me to move the router away from magnetic fields so now I have 'stuck' it to the ceiling of my apartment away from the Cordless Phone, TV etc....
Power Cycled the Modem
Updated the Mac Software
Called up the cable company to check for Firmware updates
Updated firmware on the wifi router
I then too the iMac physically to GENIUS - they kept it for a day and ran checks but did not find any issue with the system
Renewed the DHCP Lease as advised by someone on this forum
All possible approaches
Point is - this does not solve my problem. I have to click disconnect and re-connect WiFi every few minutes. It 'drops' while drafting a mail and then you have to reconnect to SEND the mail OR when streaming a movie 'LOADING' every few minutes and you have to re-connect.
What is the point of a high end computer when it cannot hold on to a wifi which my $500 Dell holds seamlessly and so does my iPhone and Wii.
Anyone have a concrete solution?

Hi
I may have a fix for you. It requires you to change your WiFI security from WPA/WPA2 to the (lower) security but effectively still pretty secure WEP. You can use the 128bit security. Some routers seem to have a problem with the passwords of WPA - I don't know the technical stuff but its happened to me not just on a mac network but on a Windows XP network aswell. I offer this to you because it worked for me, and is still working.
The thing to do is to log onto your router and change its security from WPA to WEP. To do this open your browser of choice and type in the ip address of your router. eg. 192.168.1.2 The side of your router should have this address displayed. If you have changed your router's ip address for some reason you need to use that address, obviously.
Navigate to your security page on your router. You may have to type in an Administrator password for the router. (this prevents anyone with a bit of knowledge randomly, or maliciously changing your settings and locking you out).
Select WEP security, and select 128bit if you have the option. This will give you a passkey of 26" bits" long.
Type in your new security password. Write it down EXACTLY as you type it. Remember, for WEP you can only use Hexadecimal - so numbers 0 to 9 and letters a to f in any combination. JUST make a note of it exactly, as if you don't, getting back on your router via wifi will be impossible.
Next on your iMac, or whatever, delete your wifi network connections. You could also delete your wifi connection in Network Preferences, and start again. To make things absoutley sure you can edit your keychain and delete the keychainentry for your old WPA wifi network name aswell.
Now, in Network Preferences under Network Name type the SSID of your wifi network exactly as it is on the router. The iMac will find the network and offer you a box to enter your WEP password. Type it in exactly as you remebered/wrote it down. You should now be connected to your Network using WEP security.
You shouldn't have any more problems with dropping wifi connections after sleeping your iMac and in most real world situations you will still be spretty secure.
I offer this fix "as is" - if you don't feel competent to make the changes then don't - just ask someone who does know!

Infinity connection drops every time I use the lan...

So I've discussed this on here before with no joy (https://community.bt.com/t5/BT-Infinity-Speed-Connection/connection-drops-every-time-I-get-a-call-on... and I've tried swapping out all the equipment with no success. It is driving us mad now....we have to unplug the landline if we're going to use the Internet for a protracted period, just in case!
Advice please: where do I go from here? When I use the broadband section to report a fault I end up in a dead-end of self-help docs.
Do I report it as a phone line problem (and pay for an engineer to visiit) even though the phone line tests out OK?
Solved!
Go to Solution.

Well, that will teach me to be so optimistic..
So I'm now £129 lighter and using a new line...and the broadband doesn't drop out everytime the phone rings..
BUT it drops out periodically all the time now.. AND the speed is much less than before (I get 30 Mbps on a good day..15 Mbps is typical ,and it was less than 10 Mbps today before it dropped out completely). This may sound churlish to some but I work from home sometimes and the drop in speed, coupled with the frequent disconnections, is making it unworkable...
So I've reported the fault and despite the very nice Indian woman telling me that '15 Mbps is typical for wireless' after going through a very lengthy script, I am not happy. Wireless/Wired = makes no difference..I've tried...
Since its worse than before I've asked whether than can switch me back to my old line..the call raised on the 11th was marked as resolved today although I've still no resolution even though I was promised an answer within 24 hours..and have been promised that again today...and nobody rings me on my contact number that I give them (and is in my MyBT profile) but spurious 'we tried to contact you' messages are left on my home answerphone while I'm at work...
Resolved
Broadband fault VOL011-***********
*sigh* according to the official checker I should be getting better....
(edited to remove the actual fault code since it is deemed a security risk)

ADSL connection drops every 30 - 60 mins & strange...

I recently moved house and an engineer came to connect my phone line on Thursday morning. He had a few problems: after spending about half an hour up a telegraph mast he went to the local cab for 90 minutes to fix another problem. This all took 2 or 3 hours, but eventually I had a working phone line. The engineer explained it would take a few hours more for the broadband to start working.
Later that evening, my broadband kicked in. Blue light, all happy. Straight away, my connection speed was great. I was getting results of 15Mbps from speedtest.net and a 15ms ping. This came as a surprise, as I thought new lines normally started quite slowly and then built up speed over the first couple of days.
... then my connection dropped less than 60 minutes later. I logged onto my new Home Hub 4 to find that it said the internet was disconnected. I told it to reconnect, which it promptly did. Everything was fine.... for about 30 minutes, but then it disconnected again. This time, I left the Home Hub alone. After a few minutes it sorted itself out and I had working internet again.
This has been happening constantly on loop for the past 2 days. Any suggestions?
I've tried running a few tests that have been mentioned in this forum. They seem to have some strange results!
1. If I enter my phone number into http://diagnostics.bt.com/login/?workflow=Connectivity it states that "It doesn't look like you're using a BT Home Hub", even though I am.
2. The results from btwholesale.com/includes/adsl says that I have a 1Mbps line
3. My connection stats seem to look fairly healthy, other than my connection time (it just died again when I went to take a screenshot).
Any idea?
Cheers!

have you tried a factory reset of hub using the recessed button on back and holding for 20/30 secs until lights flash?
if you do a factory reset then turn off smart setup http://bt.custhelp.com/app/answers/detail/a_id/44328/~/switching-smart-setup-on-and-off-on-the-bt-ho...
then split the networks http://bt.custhelp.com/app/answers/detail/a_id/44798/related/1
try quiet line test dial 17070 option 2 should be quiet and best with corded phone

Wireless connection drops every day -- iTunes 8.02 the problem??

Hello! Our iMac is connected to the internet via Airport, and we have rarely had problems with the connection. For the last two weeks, when I get on the iMac for the first time that day, I have to reconnect to the wireless network through the Airport Setup Assistant every single time. I've tried resetting our cable modem and Airport -- no effect on the problem. I've tried going into sleep mode without logging off to see if that might help -- nope. I've tried repairing permissions in the off-chance that that might help -- no again.
In something that seems more than just a coincidence, we updated our iTunes to 8.02 about two weeks ago, and that's when this problem began happening. I am especially suspicious that there's a link because we did not update iTunes on our Macbook and it has no problem whatsoever staying connected to the exact same wireless network.
Two questions, then:
-- Is the iTunes 8.02 update the problem?
-- If so, how do I go back to iTunes 7.7?
Thanks!

Hi, I'm new to iTunes and apple, but this is happening to me too! I've got iTunes 8 and whenever I run it, my wireless connection drops (disables itself) and cannot be restarted without rebooting the machine. Did you manage to find an answer?

Internet connection down every 20 mins

Hello, everyone
Today I asked my ISP to configure my modem/router as a bridge, and then connected a TL-WR541G (TP-LINK) router to manage ports and such.
Since then, after every 20 minutes Internet access goes down, I'm still connected (apparently) to the network, but with the exclamation mark and the legend: "No internet access" or "No network access". The only solution to this is to unplug the power supply, wait 10 seconds and plug it again. After that, Internet access is back. This generally happens every 20 mins, but it has lasted up to 1 hour with good connectivity before it goes down again.
The router has DHCP enabled, but I have a surveillance ip camera with an IP fixed to its MAC address (in order to let the port open correctly every time I reset the camera). The DHCP range, of course, doesn't include the ip fixed to the camera. Even so, I got a "two devices with the same IP" error a couple of times, even when this wasn't happening according to the connected devices list in the router configuration.
Modem: Motorola SBG901
Router: TL-WR541G
Connected devices: notebook (DELL Inspiron N4110, Windows 7), surveillance camera (TL-SC3171G), desktop PC, Tablet, 2 smartphones, Smart TV.
If any log or other information is required, please let me know.
Any help will be much appreciated.
Thanks in advance.

Wireless network drops every 5 mins

hi there,
We have a cisco 2500 wlc and (software version 7.0.220.0) and 4 access points (AIR-LAP1131AG-E-K9).
The wireless network is virtually unusable as people keep getting kicked out every 5 mins.
I've attached the trap logs. Hopefully someone more knowledgable than I can take a look? One entry I've noticed is....
Warning: Our AP with Base Radio MAC 00:3a:XX:7c:22:f0 is under attack (contained) by another AP on radio type 802.11b/g
Can anyone offer some advise on this?
Thanks in advance.
-Al

means your user have to relogin or what after 5 minutes.
Check your user idle time out and make it to 86400.(controller > General)
also check your seassion timeout, make it to 65535 (wlan > edit then go to advanced)
Then try agagin.
Hope it helps.

Connect drops every time phone rings

I have BT BB1, but I use BT analogue for phone calls (I have pay for free 24 x 7).
However everytime the phone is used, by BB connect drops.
Any ideas?

No doubt a microfilter problem. Either one is faulty, you have them configured incorrectly or you have an unfiltered telephone somewhere; Skybox is usually favourite for not being filtered as people forget it is connected to the telephone system.
If you have a microfilter problem somewhere then you are also likely not getting the best speed out of your broadband either. Usually, I find that customers broadband speed improves, as well as stability, once the filter issues are resolved
I'm a noob here so can't point you in the direction of relevant help page (yet), although I think someone did it already in a previous post.

Guest-wired access connections drop every 1- 2 minutes

I have an interesting problem.
My connections to the guest wired access drop consistanly every 1 -2 minutes. There are no drops in the mobility between the WiSM and the 4402 anchor in the DMZ. DHCp is served from the 4402 DMZ controller as well as thier authentication.
When a user connects to the guest wired access vlan some times they obtain a 169.X.X.X address and after several tries they get the proper 192.168.x.x addres. The user get thier IP address and get the redirect login. They maintain thier internet connection for only 1 - 2 minutes.
DHCP on the 4402 is set for 4hours
Any thoughts ?
Mike

Ouch, the forums ate my formatting for that first post!
Thanks for the reply Ray. I should mention that this is a shared house, not a family home, so I cannot always access the devices. I'm the one on the ethernet connection and I've gone into my ethernet adaptor's settings to change my IP address to a static number just below that of the DHCP range whilst leaving DHCP enabled for everyone else. After restarting my computer the connection's still dropping.
Haven't had a chance to reset the hub yet, if that's necessary, as other people are using the connection at the moment.
I do have the admin password for the hub but I'm under the impression a static IP address would have to be set from the devices themselves which I can't access - or can I use Home Network > Devices, check "Always use this IP address" then disable DHCP?

Why does Home share Connection drop every night?

Hello all!
I have three Apple Tv 3's hooked up, 2 wired, the other one wireless. I can stay connected to home sharing all day on all three of them without issue. But for some reason, every morning they have all three lost connection to home sharing. Even restarting the device does not reconnect it. All I can do is exit out of itunes and restart it. Then the home sharing is connected again and I can access my files.
This wouldn't be such a big deal if it was just me, but my wife does not want to have to fool with this every morning to play videos for our daughter. I was using Boxee Boxes prior to this and they worked flawlessly.
The computer does not go to sleep or hibernate and neither do the apple tv's. I have tested with firewall and anti-virus disabled. Called Apple support and they are clueless. Any ideas?

Two things jump into my mind: poor WiFi signal strength on the desktop PC or a dirty OS installation on the desktop PC. I'm quite sure that this has nothing to do with the cisco VPN client itself.
Assuming that you reach your remote workspace through the cisco VPN client it might also be that the remote part (the VPN concentrator) gets congested and drops your connection but than other employees would complain as well (can be checked with your ICT guys).
The thing is: when you lose Internet connection on your laptop while surfing a web site and connection comes back again within no time you won't notice anything. If the same happens to a system constantly receiving encrypted packets and some are missing the VPN client will drop the connection. Completely different protocols (http/ipsec) that are differently prone to packet drops...

Bell TV receptor signal drop every 4 min caused by TimeCapsule

I just got my Fibe 50 installed here in Quebec, Canada, and every 4 minutes there is a signal drop. I had 2 technicians coming home and finally we discovered that there is a DHCP conflit between both of them. When I turn off the TimeCapsule and uses only bell router, the problem disappears. Does anybody had the same problem or know if there is any configuration to solve the problem? In the TimeCapsule settings I have already changed to allow 5Hz bandwidth but did not work. Thanks a lot.

If you are supplied a router then the TC has to be in bridge mode.. that is router bridge..
Open the airport utility and make sure in the dhcp and NAT section you have it set to bridge.
Then you can set fixed channels to the wireless that are different to the bell router.. or turn off wireless altogether.. you can still access the TC via the bell router.

Linksys connection dropped after 10 mins

Hello, everyone.
I'm having a problem with my wireless router. As stated in the title, when I turn it on in the morning (I turn it off every night), it works fine for about 10 minutes, then my wireless computer will get knocked offline (the one connected directly to the router is fine and stays connected). If I reset the connection, it takes a full 2 or 3 minutes to connect (with internet abilities).
Background information:
Router: Linksys WRT54G2 V1
Computer: Dell XPSM1530 Laptop; Vista Home Premium
Please advise on what the heck to do!
Thanks
S. Wynters

well the first thing you should do is perform a firmware upgrade on your linksys router. Below is a link for you to follow.
www.linksys.com/download
After the firmware upgrade you should perform a factory reset by holding in the reset button on back of the router for 30 seconds. This will erase all previous settings, so I suggest that you write down your settings so that you can manually enter them back into the router.
Also, I would see if there are updated drivers for the wireless card at the manufactures website. See if that helps
Good Luck

Why does the connection drop every other second when streaming from iplayer through safari to apple tv?

I am trying to listen to iplayer radio through apple TV from my macbook air. When I switch back to just using the macbook the stream is consistent and works well but when I switch to airplay mode the sound stream literally drops in and out every other second. Ha! I have just gone into iTunes and I have the same issue!?
I have checked for software updates on both apple devices and restarted my router but still I have the same issue.
This is really annoying as this is the main reason I got apple TV! Can anyone help??

This may sound stupid, but I'm gonna throw it out there anyway. Is it possible, that if I have enough junk on my desktop it might disrupt the signal? It seems odd, but it kind of looks like my signal is strong and relatively steady now that I've cleaned my desktop. I do tend to get very cluttered. I use a lot of reference images and save text clippings to use later... it just piles up very quickly.
So, I wonder if all that extra effort my system has to do keeping up with the junk might have something to do with the drop outs?
