Odd FW800 behavior, frequent disconnects

Has anyone else had a problem with devices connected via FW800 being randomly disconnected, then reconnected? IE., if I have an external drive connected, it will, through no action of my own, just disappear as though it has been unplugged. OS X gives the usual spiel about ejecting a drive before disconnecting it, then the drive shows up again in just a few seconds.
This happens frequently, making the FW800 port useless. It must be the port, as I've several FW800 devices from different manufacturers that exhibit the same behavior.
Thoughts?

Hi,
I have this exact same problem with my MBP too, and both the FW400 and FW800 ports. My audio interface (FW400) and WD MyBook Home (FW400->FW800) intermittently go on and off, causing my MBP to freeze and prompt me to restart. I've re-install the associated firmwares, reset PRAM/NVRAM and I've unplugged everything, remove the battery and let it sit for about 15mins, but the problem still persists.
Forgot to mention: My device (the M-Audio interface) is still receiving bus power though.
Does anyone know a particular solution to this? I'd really appreciate it!
Thanks

HH5 / Infinity 2 - Frequent disconnects

Hi,
I had infinity installed back in October, and things were ticking over quite happily at first. In the last 6-8 weeks, I have been getting fairly frequent disconnects, averaging 2-3 a day, but peaking at 6-10 in a single day at its worst. From within the house, the HH looks to go offline for about 15 secs, then come back up and my connection to the internet is restored. As I work from home, this can often be more than a trivial annoyance, especially if I am working on a remote system or talking to a customer.
I cannot see any obvious cause from here. There is no apparent noise on the line, no odd devices plugged in or anything else which I think would explain this. I have included some information below which might be of use to people more knowledgeable than me. If more information is needed, just say.
Any thoughts gratly appreciated,
Thanks,
Rich

From http://www.dslchecker.bt.com/:
The following is from a ping polling tool running from a machine connected directly to the HH. It is set to ping google DNS 8.8.8.8 on a 1s frequency (sorry Google, but figured you could handle the extra load). The red block shows packet loss, lasting for 15s. At the same time, the HH also became unpingable, also reporting 100% packet loss. This is exactly the same behaviour I see each time.

Looks like the dlm as intervened and the speeds capped around that 54meg level.
Personnally I'd raise a fault & see if the line checks come back with anything that might need an openreach visit.
https://www.bt.com/consumerFaultTracking/public/faults/reporting.do?pageId=21
Also check if there is anything up locally with openreach's new checker tool.
http://www.homeandwork.openreach.co.uk/problems-with-your-phone-or-broadband/search.aspx
If the test come back with no fault found, then possibly research using a openreach modem with the hh5 or get a 3rd party non-bt all-in-one. These are the two main fixes people use on here.
You've probably noticed a few of simular threads about HH5 disconnects. For what ever reason the hh5 can be great on some lines but very very mischievous on others (including mine).
The Openreach modems do seem to calm things down and with being bt based everying just works including the tv box thingy with troublesome mulicasting suff.

Odd usage behavior

iPhone v101: this odd usage behavior just started half a week ago. This is the second time it happened. During standby, the usage time continues to count forward. I leave my phone on my desk not using it, but the usage still goes up. For example, the usage was 1 hour and 20 minutes when I checked like three hours ago, now it says 4 hours and some minutes. WiFi off, not running any apps, great signal and I cannot find anything running. This behavior also appear to drain the battery a little bit. The phone was not being charged or on plugged in anywhere; just sitting still on my desk. Now, the usage is back to normal and not accumulating time when I am not using it. This is strange. Have anyone else seem this happening? I had the phone for over a month now...

I didn't notice it causing any battery drain, but it sounds like I am charging it differently than you are. Here's how mine worked:
I would plug the iPhone into the wall charger at night to charge while I slept. In the morning, it would show a full charge by showing a plug on the small battery icon, but the large green battery would still have a sliver that wasn't green. The usage and standby stats would show something in the 3-4 hour range, presumably the time since it hit full charge.
I would disconnect the phone, check my email, and then take it to my desktop computer and plug it in to sync and update all my podcasts, etc. I would leave it plugged into my desktop while I showered while I got ready for work. By the time I was ready to leave, it would again show a full charge on the small icon, but now my stats would be reset to 0 and would function normally throughout the day. But nothing I did ever stopped the stats from running up during the night after attaining full charge.
1.0.1 got rid of the stats problem (they always stay at 0/0 in the morning with a full charge until I unplug the phone) AND the weird behavior of the large green battery indicator went away. Now both indicators show full charge in the morning.

Frequent disconnection from services

Hi, for years I've been a satisfied customer, but recently my internet, (along with my television signal and phone) would stop working.
Strangely enough it happens at exactly XX:05 and XX:33, about every thirty minutes.
I'm not completely sure what is going on, but the WAN Coax signal on my MI424-WR will turn off, television will black out, and my phone will ring but with no one on the other end.
They will eventually restore to normal, but this is quite annoying. Can anyone help me out?

Sorry to hear about the frequent disconnects. Sounds like an issue with your ONT with all the services effected like that. I have sent you a private message to get more information.

WRT400N - frequent disconnects on Windows 7 Enterprise

I work from home for a software company, so I'm constantly online transferring data and talking to customers via Skype & a Cisco IP Phone. I've got my work laptop PC (running Win7 Enterprise) connected to the WRT400N using a LAN cable (wireless is for a MacBook Pro my wife uses). The WRT400N is updated to the latest firmware.
The problem I'm having is that I'm getting disconnected throughout the day, and nothing short of power cycling the wireless router is fixing the problem. I've tried disabling and re-enabling the LAN adapter, ipconfig /release and /renew, and rebooting the laptop. It seems that each time, I am forced to power cycle the router to restore connectivity.
I used to use the wireless adapter on the laptop, but due to frequent disconnects I moved the router to sit directly next to my laptop and just hooked up the LAN cable. I discovered that my Comcast modem was actually dropping connectivity so I had them swap it out for an updated model and since then I can see that it's staying connected (and yes, I'll admit I'm doing the n00b test of watching the LEDs to see if they're blinking off whenever I lose connectivity now). As I type this I have actually switched back to using the wireless adapter which hasn't disconnected in the past 6 hours (a record).
Long-winded so I apologize. I really would like to resolve this issue somehow but I'm not a network expert by any means and I've exhausted my limited ability to troubleshoot.

Try to follow the below mentioned settings and then check.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter. Leave Username blank & in Password use admin in lower case.
Click on the Wireless tab
Here select manual configuration...Wireless Network mode should be mixed.
Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbors network.
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...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA2, For Encryption, select TKIP...For Passphrase input your desired WPA2 Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and remember the key.
NOTE : Passphrase should be equal to or more that 8 characters...
Click on 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.

Ichat, AIM, Adium frequently disconnect using Airport

Ichat, AIM, & Adium all frequently disconnect when using Airport. I use a Linksys Wireless Router with an Airport extreme card. When directly connected to the router, I have no problem. Using a PC with Windows XP, AIM operates fine. Safari and Firefox work fine, although sometimes I receive errors connecting to pages, when I try again no problem. Using any of the chat programs, I lose connection, but then can reconnect. After a few times, the AOL servers will prevent login.
I use COMCAST Cable internet service. My wireless router uses WEP encryption. I would switch to an AIrport Base station, but doubt it would correct the problem.
I have had this problem previously, but it corrected itself. now it is making chat programs unusable.
Any ideas?

Hi John,
By default Linksys units normally have the IP address of 192.168.1.1
Is this true for both your units or have you changed one of them ?
You may only find this out if you connect directly to the Modem one.
Also you have not said if only one of them is doing DHCP.
Example pic 3 on this page. This shows this device as getting it own contact IP address by DHCP (like from your ISP). Further down the page in the pic it shows the device is also acting as a DHCP server to the local net.
If your router is set up like this it could be getting an IP address usng DHCP like this device shows and that would tend to mean that the Modem is acting as a DHCP server as well.
If both devices still have the default IP addresses you will have conflicts, which probably explians the problems you have.

High SNR, frequent disconnects and under 15mbit sy...

I had Infinity 1 installed two weeks ago but the performance has been pretty bad.
I have the following problems:
1. I get disconnected at least twice a day and usually once every 2 hours or so.
2. My upload SNR margin seems to be stuck at 18+.
3. Even download SNR margin seems to vary a lot from about 5.8 to 8+.
4. About 25% of the time I sync at under 15mbit, which is meant to be the minimum for Infinity 1.
My current stats are below (they're about the best I've had):
5. VDSL uptime: 0 days, 10:18:11
6. Data rate: 797 / 15871
7. Maximum data rate: 1217 / 16023
8. Noise margin: 18.3 / 5.8
9. Line attenuation: 0.0 / 30.9
10. Signal attenuation: 0.0 / 25.1
Here's an example of how bad the frequent disconnects can be:

I had BT Infinity installed at the start of April and it has always disconnected multiple times per day.
Phone support said that "2-3 disconnects a day is normal" which I certainly hope is not true. Regardless, they said they'd monitor our line. Which is all they've been doing for 3 weeks.
Our disconnects are almost certainly related to wind and rain. It will disconnect within minutes of rain starting which suggests an above ground fault.
Some days are sunny with zero disconnects, but most have 2-15 disconnects a day.
Last Saturday a 2 hour long downpour resulted in disconnects every 3-4 minutes making Infinity unusable. Support said they'd continue to monitor our line...
Current stats:
6. Data rate: 797 / 13481

8. Noise margin: 18.2 / 6.2
9. Line attenuation: 0.0 / 30.7
10. Signal attenuation: 0.0 / 24.9
Download results from the BT speed tester are under the 15mbit minumum. The upload is below even the low impacted estimate.
Download Speed (Mbps): 12.63
Upload Speed (Mpbs): 0.67
Ping Latency(ms): 39.63
What does it take for somebody to actually inspect the line instead of remote monitoring from India?

Clear information from your device
To clear your history and cookies from Safari in iOS 8, tap Settings > Safari > Clear History and Website Data. In iOS 7 or earlier, tap Clear History and tap Clear Cookies and Data.

Random freezing and odd keyboard behaviors on 10.5.8

My random freezing started on 10.5.6. Updated to 10.5.7 and the problem persist. I have decided to upgrade to 10.5.8. Everything seemed fine for a day and a half. Then all of a sudden random freezing when starting, login, wake from sleep, etc.. and now odd keyboard behaviors. function keys randomly work when computer is not frozen.
I have tried every option listed in the discussions here and elsewhere. Does anyone have the same problems?

I have tried so far:
disk permissions repaired from dvd and startup,
disk first aid,cleaned caches, virus checked, zapped the pram, reset power management, ran apple hardware check, ran disk warrior, trashed network prefs, deleted sleep image, replaced directory with techtool pro, tried new user account, re-updated, removed 3rd party software, and nothing works?????

WRT54G V7 Frequent Disconnections

I've read alot about frequent disconnections using wireless routers but i've tried all sorts of different settings and find it disappointing that the wireless router (WRT54G V7) won't 'keep alive' the connection when it should.
I'm on a WinXP Pro SP2 workstation (AMD + Epox if it matters) on a built-in LAN adapter using Linksys WRT54G V7. Using my DSL directly, Windows automatically redials if I don't have a connection and will keep trying for as many times I have in configured.
When I started using Linksys Wireless router, Windows no longer prompts for login to the DSL (PPPoE) whenever I lose the connection. I don't know why. I Linksys configured to 'keep alive' for 30 secs and I've tried the following with no improvments to my situation:
- enabling/disabling the DHCP Server
- manually entering DNS 1, DNS 2
- MTU is auto
- Tried configuring both Mixed/G-only
- all other options are default to enable my laptop on wireless
Does anyone know what I can do to force Linksys to check if there is a live connection, and redial if there isn't? What's annoying is that I have to restart my workstation to get the connection back. I've tried manually disconnecting through the Linksys admin console but when IE starts returning the message 'page cannot be found' then everything is disconnected.
I've only had the router for less than a month (got it as a present for myself) and I got was disconnections. Again, if I plug the DSL directly, whenever I don't have a connection for some reason, it will automatically redial and I'm connected again. Linksys WRT54G V7 doesn't do that.
Help!

Hi...
Try reseting and reconfiguring the router. Also set it up as keep alive specify the redial period. Change the MTU setting of the router to manual and specify the value as 1300. Also the PPPoE connection on the computer should be disabled when router is dialing.

Odd display behavior

Happy New Year to All!
I just recently upgraded to Tiger. Since that time, I have noticed some rather odd display behavior on my screen. For example, when I am on web site that has a "fill-in" box, once I highlight that box to fill it in, a black rectangle stays in that position on my screen until I click on the desktop.
Likewise, if I highlight an icon on the desktop, a black rectangle outlines the icon and stays visible until I either highlight something else or click randomly on the screen.
I never noticed this behavior under Panther (10.3.9) and while it's not a huge deal, it does seem odd. It's as if the screen doesn't refresh after moving on. Any ideas?
Thanks,
Brad
P.S. After posting this message, a black rectangle corresponding to the message edit box stayed on my screen. Irritating.

Hi William,
Yes, I tried both and booted / used my Tech Tool Deluxe repair disk. All no help. Don't know if they are related, but also have other odd things going on.
Is it normal to have two Restart selections, two Shutdown selections and two Logout Selections under the Apple menu in Tiger? I do. Didn't in Panther, but can't remember if I've always had them in Tiger. Should I?
Also, can't get my scanner (All-in-one, printer works) to run in Tiger. All of these problems go away when I boot into my 10.3.9 clone on my Firewire drive. I'd really hate to return to Panther, but ...
Basically, I'm getting some very odd behavior, from a system that has always been relatively bullit-proof until now. I do all the req'd housekeeping stuff, have both Macaroni and Cocktail. Don't know what to try.

Frequent disconnect using peap wpa2 with aes and tkip

I got frequent disconnect for the users on wireless using peap wpa2 with aes and tkip.
My network is setup with :
-Wireless controller 4404
-ACS 4.0
-28 access point 1131g
-Peap authentication with active directory windows 2003
-windows xp - mschap2 with aes- tkip
when i check only aes on the wireless controller 4404 the network user are able work in a stable condition

This might similar to the bug where Wireless phones dont associate if WPA2 is configured with both AES/TKIP. In this case try to upgrade the controller.

Frequent Disconnections

Hi
Lately for the past couple weeks, my modem is frequently disconnecting and reconnecting and it is driving me nuts. The time it will stay online is random, ranging from a few minutes to a few hours. The re-connecting only takes about 20-30 seconds. It is not a phone service problem because I still have a dial tone even when I got disconnected (though I do hear some noise). Verizon techs has come to my house more than 3 times, each time claiming that the problem will never happen again. The problem would seem fixed for a day or two, but then the disconnections would happen again.
Please help!
I have a Westell 6100 modem connected to a Linksys WRT54G v5 router.

Can you explain to me, in detail, how changing my modem to bridge mode solved this problem?
I'll wait a couple more days to see if I lost any connection before checking that this problem has been resolved.
Thanks!
I am not sure but - if that resolves the issue, my guess are because the modem is
#1 buggy
#2 OR - the modem does not have a stable firmware on it. Maybe an update would fix it?

Frequent disconnections in the airport in Mac book

I recently changed my internet provider, since then i have frequent disconnections in the airport, though other units connects properly with the router. Its so frustrating that every 10 min it disconnects and it will take another 30 min to connect after repeated trials. I contacted router to find out any fire wall updates and they said its my macbook problem as other devices are working fine. Please provide any info to get rid of this frustration. Thank you..

I should also add...
BEFORE attempting any Major Upgrade... get yourself an External Hard Drive... and create a Bootable Clone Backup of your current Hard Drive...
By far the easiest way to make such a Backup, is to use something like
SuperDuper http://www.shirt-pocket.com/
or CCC http://www.bombich.com/
That way, should anything untoward happen during the Upgrade,
You will NOT LOSE ANYTHING.
(Get an EHD that is at least equal to your current Drive...)
