SRP541W drops idle connections fast

I have installed SRP541W and found a big anoying issue with this router - it drops idle TCP connections after a couple of minutes (more than 5 but less than 20) of inactivity. Namely, this "feature" becomes apparent when using ssh connections - if nothing happens in an ssh terminal for a given time, the connection is lost and the ssh client must be reconnected. As having a lot of ssh terminals open simultaneously (and, of course, leaving some them idle for a while) is a core of my work, this behavior annoys me a lot. Does anyone know how to solve this problem?
I understand that dropping idle connection is needed to keep the NAT tables reasonably small, but dropping connections after less than 20 minutes of inactivity is just way too fast and useless. Even cheap home routers usually do not drop idle connections after many hours or days of inactivity.

Also, if I switch the Airport Express to connect to the 2.4GHz network instead, the same thing happens on that network. After a few hours, the base station stops authenticating clients on the 2.4GHz network, and only the 5GHz network works.

Lenovo V560 drops wifi connection - cannot restore without reboot

Hello,
First off let me say that I'm earning a BS in Computer Science, so I know more than most when it comes to computers, yet this issue vexes me. I only say that so that any replies understand that my level of technical comprehension is far above average.
The title pretty much says it all, I have a 6month old Lenovo Ideapad V560 that cannot maintain an internet connection. Let me describe the problem in a little more detail:
PROBLEM:
This computer can connect to any wifi, and seems to drop the connection fairly randomly, however it will drop the connection FASTER when I'm more active, such as loading multiple web pages simultaneously. That said, it ALWAYS drops the connection during a session, and NOTHING I do can restore the connectivity apart from rebooting.
This issue has nothing to do with the router, as it happens on every wifi connection I've ever connected to, school, home, work, McDonalds, etc.
I've already extensively researched the issue, so please don't reply and just start linking me to related threads, I've read them, they weren't helpful.
I've done a few things already in an effort to resolve the issue, such as:
1) Re-installing Windows 7 Pro x64
2) Re-installing wifi driver
3) Disassembling the machine, removing and reinstalling the wifi Card
4) Disabling "Allow computer to turn device off" power management settings for wifi card and miniport (all network devices, actually)
5) Removing all Lenovo "bloatware"
Again, it is not a connection specific issue, it doens't matter how the connectio is configured, it seems indepedant of that.
Any help anyone can offer would be helpful!

On topic: I have the same issue with Lenovo B560 (factory installed WiFi adapter: GTC BCM4313 M).
In the same time and the same WiFi network my old Lenovo IdeaPad Y550 works perfectly.
Is there any way to make this Broadcom (or GTC?) adapter work uninterruptable?
Currently it requires to reboot or hibernate and power on again to revive adapter.
Off topic: yesterday instead of my message about the same issue posted I have seen the following error:
Please correct the highlighted errors and try again.

WRT55AGv2 dropping idle TCP connections

I have a WRT55AGv2 and it constantly is just dropping idle TCP connections. This has made it totally useless for me until I can find some fix for this. I usually have multiple SSH and FTP sessions that I just leave open all day.
This happens on both the wired and wireless interfaces.
Can anyone suggest something that could fix this?

I don't use any P2P applications and I do not use anything that generates a huge number of connections in short periods.
I've already changed the MTU setting to 1300.
I've tried disabling the wireless interfaces and just use a wired connection and it still happens. Idle TCP connections just get dropped.
What else could I try?

MacBook Air + Time Capsule frequently dropping internet connection

I too have been having frequently dropped wireless connections between my MacBook Air (MBA) and my Time Capsule(TC). My TC is connected to a cable modem and I also have an Airport Extreme Base Station (AEBS) at a different part of my house which is used to extend my network connecting via ethernet to a PC running VISTA, and wirelessly to a printer and an older MacBook. I also connect wirelessly to my home network with two iPhones, a Squeezebox 3 with a server running on the PC. I have an Apple TV and a Squeezebox 2 connected to my TC via ethernet.
When my connection drops I will either see a Time Capsule disconnect message or if I am surfing the web, the browser just hangs. The wireless ICON strength is still pegged a the max level. None of my other devices (wireless or ethernet) connected to the TC or the other AEBS seem to drop their internet connections. I can re-establish the connection on my MBA by either turning off my MBA's Airport wireless and then turning it back on or by running the network diagnostics. The latter method usually shows green lights for all but the "Internet" and the "Server" which will have yellow lights. Usually when I select my wireless network and press continue, it will prompt for my WPA2 password which I have to reenter even though I always check the box for it to remember the password in the keychain.
After reading the various discussions on disconnect problems and trying the various "solutions" I was still having the disconnect problem.
Last night, I decided to turn off my Time Capsule and was then able to maintain an internet connection for considerably longer than before. Perhaps it was one of the other "solutions" that caused that. After turning my TC back on, the disconnect problem reoccurred within about 5 minutes.
Next, I did my too frequent Time Capsule remedy which was to disconnect the power and then reconnect the power. (Seems like some of these devices (APPLE TV included) could use power switches.) I then deleted the .sparsebundle backup file on the Time Capsule. I was then able to restart Time Capsule backup and things have been running uninterrupted for over 12 hours...still backing up (20GB in 12 hours? Doesn't seem very fast!). I can report back later if this actually "fixes" my disconnect problems in the future. I am dubious that it will.
I have several questions about the MBA and the TC/Time Machine backup operation.
1.) I often forget about the TC when I close the lid on my MBA and haul it off to work. At work (connecting via ethernet), I will eventually get a TC disconnect error. But I am wondering if there are points in the backup process where a random disconnect will cause some sort of TC corruption. What is the recommended way of handling this? Should I always stop the Time Machine backup before turning off my MBA? (A nuisance if so!)
2.) What is happening when the TC backup operation stops functioning and hangs up the MBA's internet connection? (I see lots of messages logged in the system log when this happens; but, of course, I don't have much of a clue of which ones are normal and which are not normal. I could send a copy of the logs when it happens next (I am assuming it will).
Also one other anecdote. A few months back, I had taken another AEBS to my work to use during a training conference. My MBA kept dropping its connection while the other PC laptops in the room maintained their connections...(very embarrassing!). Maybe one of the other "solutions" would have fixed the problem or maybe if I had just turned off my Time Machine backup it would not have disconnected. I will repeat that exercise when I get a chance now that I have some things to try.
It seems pretty clear to me from my own experiences and the discussion reports of others that the disconnect problem lies in the MBA's wireless internet connection software or the configuration of it. It seems like it is having difficulty recovering from various wireless connection "mishaps".

Folks, I was having a very similar problem for the last 6 months. My connection was fine until June 2008, after which my Macbook and my Time Capsule would constantly conflict. If I rebooted or reset the TC, or the MB, things would be fine for a few minutes or sometimes a few hours and the problem would recur soon thereafter. About a month ago, I had to do a clean reinstall and the problem vanished for about 5 days, after which it reappeared. My MB never had a problem at work, or at someone else's home or with other routers, only with TC. Apple sent me a new TC, then they replaced my Airport card but the situation did not change ... UNTIL ABOUT AN HOUR AGO.
An hour ago, I called Apple for the nth time in the last 6 months, and the rep heard me out (just like the previous n-1 reps). He then asked me to to System Preferences --> Accounts --> Login Items and asked if Real Player Downloader showed up in my list. Indeed it did. He asked me to remove it, and told me that Apple had just figured out that the Real Player downloader was recently found to be causing a drop in the connection between Macbooks and the TC (as well Airport Express).
The problem I've been having baffled everyone. All the previous reps, the guys at the Genius Bars, nobody had a clue. Joe (the rep I spoke with this morning) seemed very confident that the removal of the Real Player Downloader from the list of login items would resolve the problem. So far, so good. My connection seems solid (its only been an hour, but earlier it would drop after 5 minutes of use).
I hope my problem that (literally!) used up hundreds of hours of my time has been finally resolved. I hope this solution will work for at least some of you as well. What gives me hope is that this solution is logically consistent with the history of my problems. I probably first downloaded Real Player in June 2008. And when I did a clean install, I remember downloading Real Player a few days after the reinstall. So I'm pretty hopeful that my issue has been finally resolved.
Shame on Real Player for putting out a defective piece of software. And thank you Joe!

Extreme Base Station suddenly dropping internet connection

I have an Extreme Base Station (802.11n Fast Ethernet) which has been providing wireless internet and printing to two imacs pretty flawlessly for several years. It seems to be a fairly simple network. DSL modem (to WAN port) and USB printer cable plugged into back of Base Station.
Several days ago, the Base Station began dropping connection to the internet every few minutes. If I connect the modem directly into the computer, I have no problems with losing connection. So, I began looking for solutions online and have been trying everything I could find to do. I've scoured the forums here, and everywhere and read a bazillion posts.
I've done a hard reset of the Base Station, I've tried different channels, I've unplugged, waited ten minutes, and replugged in a myriad of sequences, including unplugging both the modem (Zhone/Paradyne 6381-A3) and Base Station overnight. The only thing I haven't done is roll back the firmware (currently 7.4.2 I believe). I'm still experiencing the same problems and am at my wits end. I've spent hours now trying to fix it and need to do other things like shop for groceries and vacuum! So, I'm posting, in hopes someone might be able to point me in a more productive direction.
Is it possible the Base Station hardware is failing? What are the signs and symptoms? I hate to spend another $179 and still have the same problems.
Thank you.
Most kindly,
---Susan

Dear Bluenova - ( +or other interested readers+ )
I know that this reply is two months since this topic was initially posted.
This is a longstanding Airport Extreme ( AEBS ) problem that's been noted since 2006-2007.
It has been an ongoing issue for me -AND- I continue to experience it even after recently upgrading my AEBS.
I finally called AppleCare in mid-Sept. and opened a formal problem case report.
As of today (Oct 15, 2010) I still have an open & unresolved case with AppleCare.
The problem has been escalated twice -and- is now referred to Engineering Dept for research & resolution.
I was curious what steps or actions you have taken -and/or- if you still experience the problem.
_Readers Please Note_
Many users have posted messages regarding problems with Airport Extreme *+DROPPING CONNECTIONS+* .
However, with careful reading, it becomes obvious that many forum posters are not sufficiently clear
-and- often confuse or do NOT make the distinction between ..... DIFFERENT TYPES OF CONNECTION PROBLEMS.

I would like to be able to correspond directly with others via email to share info
(such as what modems, ISP's, time of day or conditions with which this problem has been found to occur)
I will then be glad to pass that info on to AppleCare in trying to find a cause (and solution) for this problem.
If this issue was treated collectively maybe AppleCare would address it with more resolve & urgency.
I'll check back with this thread for replies from other interested users.

Windows 8.1 Lock Screen drops network connectivity when screen locked using Win+L

Hi!
I was sent here from Microsoft Community forum. The question is:
Since Windows NT 4.0 I'm using Lock Screen to prevent people from accessing my computer when I'm leaving my room. First I was using CTRL+ALT+DEL / Lock Screen, then switched to Win+L keyboard shortcut when it was first introduced.
Everything was fine until I switched to Windows 8.1 computer (Sony Vaio Duo 13 with Broadcom wireless network controller). This machine is 8.1, not 8.0 upgraded to 8.1.
My problem is that when I hit Win+L combo the Lock Screen (with clock etc.) is displayed. Then, despite I have configured not to turn off display, the screen goes blank (after 30 seconds since lock) and network connectivity is cut off from desktop
apps (I suspect the system goes into Active Standby mode, because Modern UI apps like Tune-In radio keep working fine).
100% repeatable scenarios:
## Scenario 1 ##
1) Log in
2) Open desktop app that uses network connectivity. Outlook 2013 from Office365 subscription
3) Check that it has connected
4) Lock screen (Win+L)
5) Wait for 30 seconds (first incorrectly posted as few minutes) as screen goes black
6) Unlock screen (using password)
7) In right corner of Outlook app you will see "Unable to connect with Exchange server" and few seconds later it will reconnect sucessfuly
## Scenario 2 - the more annoying ##
1) Log in to Win 8.1 computer
2) Connect to it using SMB (in my case I wanted to transfer 30 GB of files from local hard drive C: to server) \\COMPUTER-NAME\c$ from Windows Server 2012 R2
3) Start copying files from computer to server
4) Lock the screen on computer
5) As soon as screen goes black server displays message "Lost connection to the resource. Try again?"
6) Unlock screen on the computer
7) Click "Try again" and it will continue copying files
My power settings are set to go into stand by after 5 hours and if I not lock the screen it doesn't go to sleep before 5 hours.
When I lock the screen using Win+L it goes into (probably Active) Standby mode.
Is there any way to prevent it from going to Active Standby when locking screen? I need the screen lock for security reasons but I don't want it to drop my network connectivity on remote desktops, file transfers and other desktop activities before 5 hour
timeout.
This issue is not related to more or less known wireless network connectivity problem that happens to many Intel Haswell computers. Mine doesn't exhibit those problems. I can easly push 100 - 200 GB of wireless data without network drops.

Same issue here using Surface 3 Pro with either internal WLAN or MS USB LAN Adapter. I'm frequently used to keep open connections over SSH to some servers. On switching to lock screen explicitly by pressing Win+L or implicitly due to idle timeout all
connections to servers are lost. In addition, I don't get any notifications on incoming Skype messages (using Skype for desktop) when lock screen is active.
Neither NIC is showing "Power Management Tab" according to step 5 of instructions above.
Additionally observing USB LAN NIC seems to be kept active after activating lock screen, but traffic stops (according to its flashing light) when lock screen is switching off display. Blanking display doesn't seem to be adjustable in System Settings (Energy
Options accessed through Win+X).
Find attached log file of powercfg -energy -duration 300 ...
Log file is in German. It basically claims unset timeouts for deactivating display while running attached to power supply though lock screen is turning off displays within 1-2 minutes.

Macbook Pro/Airport/Leopard drops Net connection after shutdown or sleep

I see all kinds of postings about problems with Airport and Leopard. I am pretty sure that the connectivity problem in my case stems from Leopard alone. I just bought a new Macbook Pro with Leopard installed. I have been using MacBooks running 10.4.x with Airport Extreme for several years with no problems. I still have no connectivity problems with 10.4, which is being used right now on the same Airport network. But, every time I shut down the Mac Pro or put it to sleep, it drops the connection. Here is a very weird thing: If I use network diagnostics, I can get back online right away after I put in my password (which is never saved). If I go through system preferences, it does not recognize my password at all (which is saved). I get this message: incompatible security. What does that mean?? There is something screwy in the Leopard software regarding security and passwords. Does anyone out there have a clue what is going on? I am not a computer expert and have no idea how to change security settings. I'm not even sure what they are. I do not want to do anything that will screw up the connectivity with the Macbooks running 10.4.11.

I had the same problem on my MacBook Pro for the last month or so after "updating" to 10.4.10. Yesterday I tried Loki's fix but couldn't connect at all after that. So I did an archive/install of 10.4.9 and it works better than ever before. I get full signal and it is a lot snappier and faster. The problem is likely in the 10.4.10 update, hopefully Apple will get that fixed in 10.4.11

Time Capsule keeps dropping network connection

I recently got a Time Capsule to replace a dead external drive and my AirPort Express. I was able to set up the Time Capsule as a router with little trouble but using it as a Time Machine backup drive is driving me crazy. Each time I start a backup the Time Capsule eventually drops my network connection before it can finish. I have about 200GB on my internal drive. Could this be too much to transfer over Wi-Fi?
I never experienced a dropped network connection when I was using the AirPort Express and my second Mac (a G4 iMac) never looses the connection. Any ideas what could be going on here?

Very interesting. Been working this problem from every angle. Noticed two kickers.
1) Transmission would refresh to fast when opening and closing menu bar airport icon.
2) Transmission never fades when running iStumbler which is continuously interrogating Time Capsule.
MacPro software seems to be forgetting that it is hooked up and drops out. It is a software thing.
I am starting iStumbler for each session automatically now and am having no drop outs. It is keeping Time Capsules attention. It is not required for all computers in the house but certainly is for the MacPro from which I control everything.
Amazing. Can one of the FanBoys bring this to the attention of the right person at Apple? Also, I need work and have many stories of trouble shooting successes. Tell them to hire me. It would save you guys a lot of time.

My i Phone drops WiFi connection after just a few minutes and wont reconnect unless I reset the network settings and reboot the phone?

My i Phone 4s has suddenly started to drop wifi connection after nealy months of near perfect connections?
To restore a wifi connection I have to reset the network settings and restart the phone, this only fixes the issues for around 2-3 mins?
Other quick fixes like switching wifi on and off/ switching to airoplane mode for a few secconds have no impact.
This is really annoying as I am using my data allowence very quickly, and as the phone is continually searching for a wifi connection the battery time has reduced dramatically.
I just wondered if any one else has the same issue, and any suggestions as to how I can fix this.
Thanks in Advance

Reboot.

Loop drops when connected wireless (NI 9191)

Hi,
I cannot figure out why a NI cDAQ 9191 chassis has connection drops when connected wireless and works
perfectly when connected thru LAN.
I wrote a little test VI to check the connection accuracy. The chassis has a NI 9375 I/O module plugged in.
A Moxa AWK3121 is used as wireles access point. What I do is check 5 digital inputs and control 3 digital outputs.
The outputs are continuously placed on/off at a different rate. I use an event loop and a main loopt that communicates
to the chassis at a loop rate of 10ms.
The chassis, laptop and Moxa A.P. are all close together on my desk. The Wifi signal is excellent.
Now, the code i written is probably not optimal.
But... If I start with connecting the chassis with a LAN cable to my laptop, Wifi Disabled, Linked Local. The communication is perfect.
No drops between the loops and the real time.
No communication errors. Runtime was 52 minutes.
Second test. Connected the chassis to the Moxa A.P. with LAN cable. Laptop connected wireless to the Moxa A.P.
Chassis still in Link Local. Ik can access the chassis in MAX. No problem.
When I run my test, I immediately see loop pauzes. After one minute there can be already a difference of 20 sec.
between calculated looptime and real time. Sometimes the active light on the chassis goes off and on.
When the active light is out, the loop is on hold. (Wich is normal as I assume the DAQ VI's are waiting for response.)
After appr.10 minutes the error -50405 "No Transfer in progress because transfer was aborted by client".
If I look at the timings there is already a difference of more then 5 minutes between the loop timing and the real time.
As last I tested with the chassis and the PC connected wireless to the Moxa A.P.
I did not get the -50405 error, but again loop drops. After 10 minutes there was a shift of 2 minutes.
Has anyone experience with wireless connections with the NI 9191 chassis?
Can I change my code? Did I mis something? (I'm a newbie to Labview)
Any help or suggestions would be appreciated.
Thanks in advance.
Frankie.

I am not clear on whether you are connecting the two together "in it's own little network" (which implies "router" and not "AP") or if you are connecting to the LAN through the wireless device (in which case it is entirely appropriate to refer to the wireelss device as an "AP"). Your last post about hot spots is what confused me.
But as you said, the biggest worry is the active light. Try using a different router/AP. I've seen routers overheat and reset themselves before due to inadequate heat sinking. i.e., Someone (not me, I swear!) dropped the AP and knocked the heat sink off the chip.
As for the delay, if you are indeed using the Moxa as an AP, are you sure you're connecting to your AP? If you're connected to a hotspot instead, your throughput will be at least halved - and maybe even 1/4 bandwidth if your AP happens to have connected to a different hotspot than you did. If you are using it as a router, try differnt bands or channels to see if you can get around any interference your company wireless network might be generating.
In general, conclude that wireless isn't the best way to connect test devices together.

After working fine for several months, my iPhone 5 has started dropping bluetooth connectivity for 2 to 5 seconds at a time with my Sony MDR-1RBT headphones. The headphones work fine with other devices. I haven't moved to ios7 yet. Any ideas?

What user troubleshooting have you done on the phone? The steps are restart, reset, restore from backup, restore as new. Understand that a restore will put the latest iOS on your device. It is also possible there is a hardware fault on the device and the Bluetooth is failing. Anything is possible given the scenario you describe.
And as far as iOS 7.x is concerned, we have 5 different iPhones here at home, all with the latest iOS, a 4, 4s, 5c, and 2-5s and all are working just fine. So, a blanket statement such as the one provided by the other poster is not completely true. Others are not having any issues at all either.

I have Snow Leopard 10.6.8 on my MacBook. Constantly dropping internet connection or message "error connecting to the network" comes up. No wireless connectivity issues with windows 7 laptop or iphone.

I have a MacBook with Snow Leopard 10.6.8. The last few weeks it has been constantly dropping internet connection, and one of these messages appear on the page: "Safari cannot open this page because the server where this page is located isn't responding" or "Safari cannot open this page because you are not connected to the internet" comes up. I will check Wifi and I am connected. No wifi connectivity issues with iphone or windows 7 laptop, this doesn't happen with either of those devices. I have unplugged and reset router, cleared cache, still happening. Any ideas? Thanks in advance.

IPad Air after upgrade to ios 8 continue to drop WiFi connection

On September 19, I upgrade my ipad air to ios 8, and it had been dropping Wifi connection ever since. I was browsing using Chrome and next thing the browser hang up; then error message informed me to no network connection. By the way, my network was strong (5 bars), because I was streaming to my Roku in HD without any issues. At the same time, my Airplay do not want to stream the content in full screen either. It only mirror what have see on my ipad, not allow me to go full screen on TV. I hoped Apple will step up and correct this issue as soon as possible; I miss the good old day of reliable upgrade from Apple.

Yes, and hopeful 8.1.1 will help. It's supposedly in beta testing.
