SRP521 Lan connections drop once wan is connected

I have had this issue on the last 3 srp521's I deployed, all were pulled from service and replaced with a different model. Firmware is 1.1.24 and I also tried on with 1.1.27
With only power and 1 lan connection I start a ping to the router and a ping through it to the DG of the wan ip. When I plug in the wan cable I get a single reply from the wan ip DG and then my lan connection drops. I have to power cycle the router to get it to come back. I have a static set on the WAN and am using 10.10.10.x on the lan side. The link light on the router stays on for both lan and wan.
Any idea on what to look at?

Hi Sage,
I'm not sure that I follow what you mean when you say the WAN goes down as soon as it is connected. Could you provide more detail please? Can you specify what address you are using for the WAN and LAN (with masks).
Also, I'm not sure what you mean by:
I plugged it into the its own switch and it went down as soon as connected
Regards,
Andy

Frequent wireless connection drops: how to re-connect?

My wireless connection has become quite unreliable of late, and I'm not sure how to diagnose/fix the problem. Configuration:
MacBook Pro4,1
Intel Core2 Duo
Max OS X 10.6.6
When the connection drops, I first try to "Turn Airport On" with the menu bar, but this has no effect.
Using Network Preferences to "Turn Aiport On" also has no effect.
Turning to the command line, I try 'ifconfig -a', and get:
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
status: inactive
I tried bouncing the en1 interface using:
ifconfig en1 down
ifconfig en1 up
But the status stays inactive. Any thoughts on what I should try? A reboot always
resets things and gets them working again, but it's incredibly annoying to have to
reboot when in the middle of something.

It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease".
6) In the folder /Library/Preferences ( not <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
They may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

E4200 connection dropped once homeplug connected

HI,
I just installed a E4200, and found that once I connected my Homeplug Powerline to E4200, the connected (wired / wireless) computer (with E4200) connection will be dropped. The connection become normal again once I disconnected the Homeplug with E4200.
Here is the error description from Cisco Connect: An HNAP call to the device failed because the HTTP connection was broken.
Does someone know what is going on? I will appreciate any comments & replies.
Many thanks!

There might be some settings required in the router so that it gets the proper solution. If you are facing the concern of getting lag, dropped connections then you can try the following steps:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] On that same setup page reduce the MTU value to 1400 from Auto
4] Then go to the Wireless tab, keep network mode as mixed,
For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.

Connection drops or extremely slow connection

Hello,
I have an Early 2008 Macbook Pro with Mac OS X 10.5.5. By the time I was running on 10.5.2 my Wi-Fi connection used to work perfectly, but when I updated to 10.5.3 I started to have so many problems with it that I even went back to 10.5.2 for a while.
I remember posting a thread in a forum and people answered me that it was impossible for a software update to mess up my connection. I proved it by downgrading and gaining full connectivity back. I've also found hundreds of people who have been having the exact same problem, but it appears as if Apple just doesn't care enough to give a definitive solution. Instead, I've tried tons of other so-called solutions from other people, that have not done anything good for me.
The problem is as follows: I can perfectly connect to my home network, but after 30 seconds- 2 minutes, my signal drops to just 1 bar (from full 4 bars) and I can no longer use it. To fix it, I have to disable my Airport card and then enable it back, to get another 30 seconds - 2 minutes. If I ever get to be connected for more than 2 minutes, my connection gets reaaaally slow (as slow that it can take me more than 5 minutes to download a 100 KB file).
Anyway, I'm 100% sure this is a SOFTWARE issue since the same computer running on Windows and resting at the exact same place doesn't have a single problem connecting. Of course, it has nothing to do with my router configuration. It is completely, entirely, 100% a problem related to Mac OS X 10.5.3 and above.
I love my computer in many ways, but this issue has been killing me bit by bit. What does a computer without a proper Internet connection work for? Then you can remotely understand my frustration.
Please, if you have had the same problem post it here. Apple has to do something about this, because I can't believe I bought such a useless computer!
Thanks.

TMG Stops responding every 4 days / many connection drops with idle vpn connections

Hi everyone!
I am running a TMG Firewall with about 200 users connected on Server 2008 R2 - patch level 7.0.9193.601.
It is virtualized on a Hyper-V 2008 R2. Additionally we have 4 IPsec Site2Site VPNs configured in Windows Advanced Firewall - as TMG doesn't provide such a comfortable way to configure them directly in TMG.
About 3 Months ago that TMG started to lose connectivity from time to time. At first we were not monitoring that problem precisely as we thought it was an isp issue but some days before christmas that tmg server just dropepd every outgoing connection
and stopped listening!
I was able to control the server over hyper-v directly but no connection in or outbound could be established. (no VPN inc or surf outgoing)
I checked the event logs and there was NO other error than the errors from TMG connection verifiers...
As far as I was able to tell tmg still worked as far as logs and engine was conserned but no routing was done at all!
The last resort was to reboot the TMG then everything worked as before...
This behavior then appeard every 4 days... - simple workaround scheduled reboot every 3 days!
But that is no statisfying solution.... additionally some vpn users reported that their connections has quite annoying drops from time to time, unfortunately I was not able to trace the error.
Possible sources that I can exclude:
-Backup (online snapshot with ArcServe - the server was NOT saved)
-AV (Symantec Endpoint protection 12.1 - was uninstalled nothing changed)
Any ideas??
Best regards

Hi,
opening a MS case seems not to be so easy...
As long as I have no clue whats going on exactly there is no ms case.
Any other suggestions??
I started collecting Perfmon data: everything seems to be OK.
- hardly any backlogged packets
- during working hours about 10 pages / sec (memory)
Some Values:
Free System Page Table Entries: 33.555
Pool Nonpaged Bytes: 88.646.372 Bytes = 84,53 MB
Pool Paged Bytes: 266.842.112 Bytes = 254,48 MB
System Driver Total Bytes: 4.812.800 Bytes = 4,5MB
Handle Count (wspsrv): 11.338Private Bytes (wspsrv): 821.944.320 Bytes = 783,86 MB
Working Set (wspsrv): 609.697.792 Bytes = 581,4 MB
Virtual Bytes (wspsrv): 1.747.615.744 Bytes = 1,666 GBThread Count (wspsrv): 69
I'll keep collecting data for two days because my last reboot was 2 days ago - if my observations were correct TMG will stop responding monday morning or during lunchtime at latest.

Wrt54gs router to internet cable modem connection drop

With the wrt54gs router set at auto dhcp and mostly on default settings, after some time of inactivity the connection between the router and internet cable modem drops out. That is, when there is no activity (no transmission to/from internet) the connection drops and the wireless connections shows "local only." Any suggestions/comments on why this is so? Thanks!

Have you tried to connect the Modem to the computer and checked if you are facing the same problem or not?
On your Router setup page, change the MTU size from AUTO to Manual and change the Size from 1500 to 1350 and click on Save Settings..... Then click on the Wireless tab and below Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Click on the sub tab under Wireless "Advanced Wireless Settings"
Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings...
Now see if you can locate your Wireless Network and attempt to connect...

Streaming bbc radio, connection drops out, have to manually reload.

W7 pc, 4GB ram, virus/malware free. 10 mb/s cable access.
I stream BBC radio 4 in separate window. PROBLEM - connection drops out, never re-connects, have to manually reload. Changing BBC feed from nornal to low bandwidth makes no difference. No ISP bandwidth cap. No problems with other downloads (updates, jpegs etc).
Is there a download manager - don't think it can be the BBC site.

BBC at least in the past has often had problems with its Edge Servers and so listeners outside the UK would have problems that took a long while to be solved, the BBC's support system often failed to pass on info regarding problems. Specific countries/ISP s would have problems but as long as the UK service was unaffected the BBC tended not to notice.
I have not recently used BBC iPlayer online. The overseas low/high bandwidth on the iPlayer stream did not do anything other than restart the stream, overseas users only got the one low bandwidth, the option was an artefact.
AFAIK the BBC does still stream Flash and Windows
* http://faq.external.bbc.co.uk/questions/radio/online_radiohowto
As you are using a Widows computer try both streams one may work still.
The BBC no longer has a support forum, but you could look at

Net connection trouble: "No Ethernet cable connected or the device is not responding"

Hello
I have been plagued by a dropping Net connection for a couple of months, and as it has been getting worse lately I have tried to sort out the problem.
I have simplyfied my connection between the computers and the VSDL fiber modem by bypassing my AirPort Express and Ethernet hub and connecting the three computers directly to the built in ports on the modem.
Since I did that a new error message has started appearing on my Mac Mini, saying that I have no Ethernet cable connected to the modem, or the device is not responding. At the moment I have two of the machines connected, and the Mac Book Air seems to work without problems. There are lights on the Ethernet ports on the modem, and they are lighting up for the iBook even when the Mac Mini connection drops. When the Mac Mini connection drops the lights go off on its Ethernet port on the modem.
This seems to point to some sort of trouble with the Mac Mini. Is there a way to monitor what's going on? Can I use Terminal, for instace? It can't be the settings, and it cant' be the cable, so it must be related to the hardware I suppose. I am using DHCP to connect to the modem.
The connection drops arbitrarily, sometimes for long periods of time, and then comes back up again by itself.
Any ideas for trouble shooting etc?
Best

Thanks again. Unfortunately, the problems are back again. Had a stable connection and connected the AirPort again. Everything was working fine. Then all of a sudden the connection dropped again today.h
Connected a LAN cable directly to my MacBook Air and got the connection to work immediately.
Took that cable and connected to my MacMini, again, connection came back immediately.
The AirPort (in Brigde Mode) is also connected, but gives me a blinking orange light, and the same "no cable or (modem) is not responding" message again.
I guess this must rule out hardware problems in the computers.
Ligth for the LAN cable port on the modem connected to AirPort is dead. Moved the cable to another port, light still dead.
Shut down AirPort Express, still same orange blinking light when I switched it on.
I now suspect there is something going on with the AirPort Express. Just bought it, and I had the same problem with it's predecessor, but...
Is there any way to trouble shoot the AirPort Express?
I can connect to it Wirelessly, But AirPort Utility says it has been removed from the Network. In the Network Preferences it says it has a self-assigned IP. For Network Settings I get green lights for everything except Network Settings, which gives me a yellow light. It also says the Internet connetcion is working correctly.
Indeed, when I made the direct Ethernet connection inactive I still get a working connection over WiFi, in spite of the blinking orange light on the AirPort and a yellow light for Network settings in Prefereces....
In the console things look normal:

E3000RM - WAN connection dropped

Pros: Good Price. Worked very well when it did operate.
Cons: I purchased this approximately 5 weeks before I got around to using it. After installation, it worked for two days and failed. The WAN connection dropped, and numerous attemps to reconnect failed. Since I was approximately one week past the expiry date of the warrenty I guess I am out of luck and learned a lesson to test upon receipt.

In this case you can reset the router and try to run the cisco connect software that came along with the router to reconfigure it (Note: If you already have cisco connect on your computer then uninstall it first before reinstalling it.). After that you can get into the advance settings of the router through cisco connect and try to reduce the MTU size to 1400.
Click on the following link that shows how to reduce the MTU size http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=66270e5d0d4347d087102f2bfef7116d_3742.xml&pid=80&r...

My airport express frequently drops the internet connection. Once I unplug it and re-plug it in, everything is fine until it drops the signal again. This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

My airport express frequently drops the internet connection. Once I unplug it, and re-plug it in, my Macbook Pro17,IMac 24, iPad air and my wife's Acer 15 works fine until it drops the signal again. This happens on a regular basis. Is there anything I can do ensure it maintains the internet connection?

It is tricky..
But yes it can be done as long as you use a different IP subnet to what is being used for the internet..
So I need to know what modem router you have?? Does it have wireless as that would make it very easy?
What IP is the computer getting?
Then I can give you the details to setup wireless statically on a different subnet.

WRT160Nv2 - LAN connection drops

I have just purchased and installed a WRT160N. Wireless connection works fine.
Wired connection also OK but it drops with no errors in logs: Can't connect to URLs but connection status is "connected".
IP release /renew seems to fix issue but this is not workable long term as this happens several times a day.
Anyone have any ideas?
Solved!
Go to Solution.

There is a known issue with intermittent connectivity and the Build 11 firmware for the WRT160N V2. Build 11 is the current firmware on the Linksys site. Check to see if you have Build 11 if your router is a V2.
Downgrading to Build 8 is generally accepted to correct these issues, however Linksys have indicated to several people they do not have the build 8 firmware to give to end users.
This is ONLY for WRT160N V2 routers. This firware will not work on WRT160N V1.

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....

How to troubleshoot intermittent connection drops on Apple LAN (TimeCapsule AirPorts)

Hi all, I have built out a wireless network for an office space. The network consists of a TimeCapsule acting as a router w/ dhcp and 3 Apple AirPorts acting as access points to the TC. I have gotten reports from users that there has been random connection drops (symptom: wireless internet stops working breaking AirPlay, etc.). Is there a way to review router logs to see what happened? Are there any proactive tools I can install to monitor connection drops?
I have Logmein Central and can make one of the computers a Logmein Pro client but the alerting on that is very weak, looking for something more. Please help!

I want to connect an Airport Express via WiFi to my internet connection and then connect its LAN port to the WAN port of a Time Capsule. Will then any device connected to the time capsule wirelessly be also connected to the internet?

Background is I can't hook up my time capsule directly to my internet connection via network cable. I tried to extend the network via Wifi, but that did not work. At the moment I have two wireless networks, one with internet connection and another one with my time capsule. So to use time machine I have to change my network all the time.
Can I buy an Airport Express, use is as a client to my internet connection wifi and provide that connection via network cable to my time capsule and all it's wifi clients?

The AirPort Express will connect to your existing wireless network if the network is using WPA2 Personal or WPA/WPA2 Personal wireless security settings.
So, it can join the network as a client and then provide an Ethernet signal to your Time Capsule.
Be sure to configure the Time Capsule to operate in Bridge Mode so that it will be operating on the same network.

VPN connects when on LAN but not via WAN

Hi Guys,
I've recently configured a VPN on my SLS. I uses the following settings:
L2TP over IPsec
PPP Authentication: Directory Services: MS-CHAPv2
Shared Secret: xxxxxxxxx
Client Information:
DNS Servers: 10.0.1.250 (my server) 10.0.1.1 (my airport extreme) - This is where I think I'm going wrong
In my SLS firewall I've open every possible port for both L2TP, PPTP and all required directory authentication ports I believe. If there are any tricky ones please let me know
I am able to successfully connect to the VPN and route all traffic to the delegated IP when on my local network. However when ever I'm away from that network - friends, work, and various other tested internet connections - I am unable to connect to the VPN.
I've ruled out the SLS firewall by turning it of for several days and trying to connect at several locations. I've checked the log on the VPN and there is no record of even an attempt to connect.
In Security of Server Preferences i have exposed the VPN on the airport extreme. I've tried both with and without port forwarding. As far as i know (correct me if I'm wrong) because I have my domain name resolving to my server then I don't need port forwarding. My DNS works for all other services on the SLS.
Any ideas at to what I might be doing wrong? Things I could try to isolate the problem?
Any suggestions would be very handy!

Your Airport Extreme does not contain a DNS server.
Ensure MobileMe is disabled at your Airport. That messes up VPN pass-through.
From a remote network, confirm that all of the necessary ports are open via nmap or Applications > Utilities > Network Utility or other tools.
Quadruple-check the list of ports (and preferably with a second and third technical resource), as the Apple documentation around L2TP port pass-through with Airport and Time Capsule is murky.
Ensure that you don't have the same subnet on both ends of the VPN connection as that can interfere with IP routing.
Also try testing with PPTP, in place of L2TP.
I'm in the midst of tussling with a recalcitrant VPN router myself, but that's another topic.
