On the subject of dropped connections..

I have a MBpro 15" CD. I also have a Netgear WGT624 and two WG602v3 (access Points).
I use the 602's to bridge a connection to my living room which has almost no signal when connecting with the WGT624, due to distance issues. Furthermore, I needed a signal boost for my TIVO's USB Netgear wirless adaptor.
Here is what I have noticed:
When connected to the WGT624 I never drop a signal even when I have almost no signal left due to distance from router. However, when connecting to my WG602, the MB drops the signal every 10 min or so, even if i have full signal. My TIVO which is connected exclusively to the same WG602 does not experience dropped signal issues.
I had read about the sudden dropped connections from other MBpro users but I never experienced one untill recently because I almost never connected to the internet using my WG602.
From what I understand there is no solution for the sudden dropped connection. Changing routers will most probably solve your dropped signal issues. I think it's rather sad that one has to resort to that, but hey, if apple wont solve the problem, you have to....

What is the difference between dropping-connection and reset?

Hi, Im currently studying HTTP MPF (ASA feature) ,
im just wondering about the difference between dropping-connection and reset (TCP)
can you please tell me how it drop and how it reset ? ?? specific process of it ( eg, TCP handshake, etc)
thanks in advance. !

Reset sends a tcp response with the rst flag set. Drop sends no response.

RE4000W Drops Connection

I recently purchased a RE4000W and managed to get it up and running and the speeds are really nice, when it keeps a connection. It seems that every 30ish minutes it will drop connection to my router and automatically reconnect. Now, this is not an issue while I am surfing the web or even when I stream a movie (buffer prevents a drop). The problem is when I am gaming and the connection drops, so does my gaming session.
Here is how I have it setup.
Static IP address on the extender and also assigned on the router via the mac address.
CAT5 cable, or wireless, to the computer (still drops connection).
It is using channel 11 and the router is on AUTO for a channel.
There are no major obstacles between the RE4000W and the router (e.g. washer/dryer...etc)
Here is what I have attempted to fix this problem.
Updated the firmware
Have tried using CAT5 connection or Wireless
Moved the extender to various locations
DHCP or Static IP Address
Factory reset (many times)
Restarted the router and RE4000W many times to let them synch up
Has anyone else seen this problem?
Additionally, I have two other repeaters/bridges in other locations of the house with static ip addresses and they work perfectly. They are older Linksys routers that I converted into a bridge / repeater to help with dead wireless spots.
Thanks in advance for all the advice / help.

What I finally did was relocate the RE4000W into my kids bedroom w/o it being connected to a CAT5 cable. So far this seems to work. The problem *could* have been that my RE4000W and router were too close to each other and therefore fighting each other for 2.4 WIFI signal. Now, the RE4000W is further away from the router, not physically connected to a computer and all is well.
I have placed an order for a 1900AC router and it should be here next week. This router install just might make the RE4000W obsolete.

Broadband Dropping connection, fixed but now gamin...

Hi
Last Sunday our broadband connection was dropping every 15 or so minutes, I called BT and reported the fault. The lady asked me to remove the cover from our BT wall socket and plug the ADSL modem into a diagnostic socket but there was no socket visible after removing the wall plate. She then did a line check and confirmed a problem with the line at the house and an engineer would call me at 9am the next day.
9am on the dot I got a call from the same lady asking if the problem still persisted as they had made some changes. I left a ping test running which gave me a 100% success rate over 20 or so minutes (previous day it was 19% success rate over the same time). So she said they think its fixed and to keep an eye on the line over the next few days.
So, I think the line noise has been cleared up (about 8 months ago I asked for interleaving to be disabled), so the broadband isn't dropping it's connection but now my gaming pings have gone up and latency is awfull, I play Call of Duty Black Ops almost every night so any change in my connection is quite noticicble. People kill me before I even see them and its so frustrating that I can't play like this, not good when your in a clan.
I assume they put Interleaving back on to fix the problem of dropping connections? but now the older gaming problem is back.
Any help is much appreciated.

your noise margin is still a bit high at 12 as normal is about 6 and when the margin drops you should be up to 8mb being max for adslmax
can you run btspeedtester and post the results

Linksys E2000 drops connection

Hey everyone, I have had my Linksys E2000 for a few months now. But up until now, I havent used the wireless settings too much, I have had everything hardwired into the router.
I decided last week to set up the wireless settings so that I can connect my PC and Xbox's wirelessly. They are all within about 10 feet from the router. The connection is fine for a while, but after a few days it begins to degrade. I opened up a command line and pinged 192.168.1.1 to see results of 150+ms on my PC wirelessly. Wired it was about 2ms.
All of my devices have a static IP address on the LAN, and one of my Xbox's is in the DMZ, still dropping connection often. I moved my PC and DMZ Xbox to another room on the second floor of my house and its still about the same speed.
I set my old wireless G router up and its working fine......but I use my PC as a home media server, so 54mbps is very slow for media that needs upwards of 100+mbps. My ISP subscription is about 12mbps, which I get all 12 of those on a hardwired machine, but a wireless on the E2000 is lucky to get 3 of those.
I have everything set up correctly in the router settings, MTU of 1500, with only Wireless N broadcasting. I also noticed that the E2000 will drop connection much faster if the SSID is hidden.My old Wireless G router is getting pings of less then 1ms wirelessly.
I have the Xbox S models and my wireless adapter is a Edimax wireless N adapter. Could this be a defective router? Any options to try to fix the problems?

I'm experiencing similar problems as well. I'm going to try these settings out and see what happens. Reseting my router fixes the problem, but I don't want to have to do this once a week or more. My WRT54GS worked great, but I wanted the speed that N had to offer. Its rather annoying because I hate having to go upstairs every time I need to reset my router in order to get an IP address on my wireless laptop downstairs.
This seems to be an apparent problem among Wireless-N in general. D-Link, Linksys and Netgear all seem to have problems with dropped wireless-N connections on their routers too. Read the reviews on Amazon & Newegg for yourself.

WRT610n dropping connection thread

This is the problem we see the most on different forums.
People report that using both bands with some heavy traffic make the unit to drop connections. Yet the heat is suspected and some have managed to get rid of that problem by allowing the unit to run cooler.
If you are experiencing dropping connections, can you try to find a way to cool the unit (without voiding the warranty) and report if you still experience the problem? Maybe a fan blowing air directly on the unit.
This is a brand new router and may have not been fully tested with large tranfer on both bands simultanously where heat is more susceptible to occur with the CPU running non-stop.

I posted my experiences in a few other forums, but since this is the official Linksys forum I'll post here, too.
I got my WRT610N a few weeks ago, primarily to use the 5GHz 802.11n radio to stream 1080p HD content to an HTPC. The initial setup was easy, as I'm an IT consultant and have had my fair share of experience with consumer routers such as this.
After about two weeks of near perfect functionality, my router suddenly started dropping the wireless connection every time I tried to stream HD content or do a significant file transfer that lasted over an extended period of time. Because the HTPC was actively streaming the HD content real-time, there was constant 2-3MB/sec activity -- I was able to get halfway through a movie before I started getting incessant dropped connections. I tried upgrading to the latest Build 18 firmware, but did not see any improvement.
In a room with ambient temperatures in the high 70's, I felt the router with my hand and found that it was quite hot -- the bottom especially, was clearly hotter than it should have been. After fumbling around with different configuration settings (disabling WMM, etc.) I eventually found that completely disabling the 2.4GHz radio partially alleviated the problem. However, on a particularly hot Summer day the problem happened to me again, even with the 2.4GHz radio disabled.
I had read countless posts of people with the same problems -- despite multiple hours of telephone calls with the highest level of tech support, the Linksys people were unable to help to solve the problem. Which is pretty understandable, really, seeing that I believe this to mainly be a hardware design problem where the case simply doesn't have enough airflow to effectively cool the dual radios.
Anyways, since I'm technically inclined, I decided to fix the problem myself. I took apart the router (which voided the warranty.. don't do this!) and installed some slim-profile heat sinks on the metal shields that covered the hottest chips on the board. I also replaced the only heat sink installed at the factory with a larger one. I installed all of the heat sinks with Arctic Silver Alumina Adhesive Thermal Paste.
Additionally, I fashioned up a base stand with a quiet 120mm fan positioned directly under the router, forcing air up through the holes in the bottom of the router, around the heat sinks installed over the hot chips, and out of the top vents near the antennas. This provided decent air circulation within the unit.
Afterward, I setup a stress test to run overnight. One client connected via the 5GHz radio, and was queued to transfer around 100GB at ~10MB/sec, without stop. Another client connected via the 2.4GHz radio, and was queued to transfer 50GB. A final client connected via the GigE switch, and was queued to transfer 180GB at around ~65MB/sec.
I woke up in the morning and found that all transfers had completed successfully without a single hitch the entire night. I touched the router with my hand about an hour after the start of the test, and found that it was not hot at all -- in fact it was barely warm to the touch.
Anyways, that was last week and since then I've streamed multiple movies and done multiple file transfers without any hitches. I'm not telling people to void their warranty's, and I'm not responsible if you try this yourself and screw up your router. I'm just providing evidence that strongly supports my hypothesis that the WRT610N connection drop issues are due to overheating, and can't simply be fixed with firmware updates.
To Linksys: I suggest you look into a better method of cooling this router. On a slim device, such as the WRT610N, which can't be stood on its side for better airflow, and which runs dual wireless radios simultaneously, a single, small heat sink on one of the chips just doesn't cut it. Also, if you do a hardware revision and want to send me a new one for helping out, let me know .
Here are some pics of the base stand I made. I didn't take pics of the heat sinks and it's probably better I don't post that here anyways...

Server dropped connection without sending the initial SMTP greeting

Whenever anyone tries to send email to addresses from the domain 'cwbank.com' they receive the error emessage:
connect to smtp.ab.tac.net[216.123.224.167]: server dropped connection without sending the initial SMTP greeting
If I use other mail servers, the message goes through without a hitch.
Prior to this week we could send email to this domain.
Port 25 is open on the receiving server (216.123.224.167).
A few weeks ago, we were 'blacklisted' because another server on the same subnet was spamming. And a few ISPs (Godaddy, 1and1, etc.) blacklisted the whole subnet instead of the offending IP. We don't seem to be having any more problems with getting RBL rejections anymore. Typically those error messages were returned as '550 RBL rejection' errors. I'm wondering if this might be related.
Any other thoughts on the subject?

Well, the other thing that could be happening is that the mail servers at these 4 IPs might have their own hardwired IP block on some range of IPs that you are in. We know that is not being done at their firewall (you can connect and get the greeting), but might be done with, for example, a postfix config that prohibits connections from certain IP ranges.
There's another possibility, namely, that they are picky about DNS config. Your IP of 68.150.192.151 seems to have a good reverse DNS PTR record that matches the SMTP HELO greeting when I telnet to your server:
mail:~ admin$ telnet 68.150.192.151 25
Trying 68.150.192.151...

Maybe they won't talk to any server whose name given in the Reverse DNS PTR record doesn't have an A Record that matches. You might want to check that.

While using the computer the wi fi dropped out and it can longer find any networks. I have played around with the air port etc , still have no networks and can't connect to internet. Please help

Hi I am having Wi fi connectivity issues , while using my computer the wi fi dropped out , I can no longer connect and no networks come up. I have tried looking into the air port, trying manually to connect to the desired network with no success , it says the Wi fi is turned on. I am at a loss to why it will no longer connect, please if you have any suggestions,as I tried to ring apple support but my warranty has expired this is my first major issue since I purchased it in 2009.
Thanks

My 4s i-phone which is 2 years old cannot find any wi-fi networks not even my home network... I had the same problem two months ago but i turned off the i-phone for 8 hours and then it was okay... Now it happened again.... I tried to restart the modem but whilst my laptop is connected regularly, my phone still cannot find any wi-fi networks... I restart the i-phone, i reset it, i chose reset network settings, reset all settings, i turned it off for a whole day in case it was overloaded, i turned on the airplane mode and turned it off again, i put it into the freezer for 10 minutes within a zipped bag but 3 days now and i still cannot be connected to my home wifi... I went to the technician today and he told me that it means that wi-fi is broken and that i need to change it with a charge of 70 euro but i have to give my phone for 10 working days so as to be fixed... I am so frustrated and i don't know if i want to give 70 euro for wifi since i don't know if it would make the same problems again...

Just installed IOS 8 to iphone 5 and cannot connect to WI FI. Sometimes connects and when I begin to use the phone ot drops out.

Just installed IOS 8 to iphone 5 and cannot connect to WI FI. Sometimes connects and when I begin to use the phone ot drops out.
I have attempted all the regular trouble shoots such as resets, complete restore and reinstallation of ios 8. no change.

I don't have an answer for you but from my experience iOS WiFi syncing has always been a hit and miss affair (more miss than hit I'm afraid). I have gotten to the stage where I rarely use the WiFi sync. It is just quicker, easier and much less stressful to use the USB cable. I am having the same issues with all the iOS devices in our family which includes various models of iPhone, iPad and an iPod Touch and have been having them since WiFi syncing was introduced (in iOS5 ???). And then I have not even mentioned my favorite iTunes syncing messages: "Waiting for items to copy" and "Waiting for changes to be applied"!
iTunes is always extremely quick and eager to pick up the devices but as soon as I click on sync it shows "Looking for iDevice" and then the device disappears. I have found that initiating the sync from the Settings app on the device prevents this issue.
It does however seem as if it is worse with Windows 7. I did not have so many issues with my previous Windows Vista PC.
Sorry I cannot be of any help.

Since upgrading to Yosemite I am getting frequently "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again"

Since upgrading to Yosemite on my iMac I am frequently getting "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again". This is with both a WiFi and Ethernet connection. The server is working fine from other devices using WiFi onto it such as iPhones, iPads, MacBook (which is also on Yosemite) so don't believe its an issue with the server.
I am also noticing page load very slowly when this problem is not occurring.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Since I have done the iOS 4.3.5 update the Personal Hotspot drops the Internet Connection every approx. 10 minutes

Hi,
I'm having the following issue: sincer i've done the iOS 4.3.5 update the Personal Hotspot doesn't work fine anymore on my iPhone 4. My Windows 7 Laptop or the ipad are loosing connection each more or less 10 minutes. I have tried to connect the phone to the Laptop via Cable (not only WiFi) and I have the same issue.
The phone is neverlocked.
I've already tried to reset the network settings but the issue is still there.
Does anyone have an ideea?

We are having the same issues on our two iPad 1's. The only thing we have not done yet, in addition to your list above, is turn off the router.
From seasoned iPad users (we've only had our a few months): how long doe it take Apple to fix this type of blunder?
This is so frustrating. I used to rave about my iPad, but if this is my new life with it: dropped connections, half loaded pages, stalled out pages, a multitude of strange error messages, this is not a product I can rave about. I miss my "old" iPad!

Since Updating to 10.9.5 Safari and the App Store drop internet connection periodically while other apps Mailplane and Epic Browser continue to work ?

Hello.
Since Updating to 10.9.5 Safari and the App Store drop internet connection periodically while other apps Mailplane and Epic Browser continue to work ?
Never had this problem previously running a Macmini Server 2010 with the latest Mavericks Updates
Tried reinstalling over my existing OS and seemed ok until I once again updated to the latest security and Safari updates
Any ideas ?
Using ethernet but wireless acts same,
Cliff

I also forgot to note that this problem also persists with the new iBooks application. I cannot get past the 'Get Started' screen or access the iBooks Store. Again, all top bar menus are unresponsive.
