Intermittant network disconnect while tethering

I have both an Iphone 3G and Iphone 4. This problem only occurs with the Iphone 4.
After a few minutes of surfing on my Win 7 64 bit desktop while tethered, I get a yellow exclamation point in my status bar and I can no longer surf the web. When I hit "troubleshoot connectivity issues" the adapter resets and I can surf again.. for a few minutes. Then the problem returns.
Sometimes I can surf for 5 minutes, other times 20 minutes... but the problem always comes back.
Does anyone have any ideas for this? I do not notice the problem with my 3G phone, but I prefer to tether with the Iphone 4 as its upload speed seems quicker. (Verified with DSLreports.com)
Thanks.
P.S. The issue occured while typing this!

I think I found the problem... and it goes to show that the Iphone 4 antenna is not as sensitive as the Iphone 3G or 3GS.
Before the update(4.0.1).. both phones showed 5 bars. I new that was a crock because I live out in the boonies. So far in fact, my ONLY internet option is tethering. I'm thankful I am in a 3G area.
After the update, I get 2 to 3 bars. That seems more realistic. Especially when I tried a USB dongle before tethering was available, and it only showed 1 to 2 bars.
While surfing, I have placed my Iphone higher up.. where the dongle used to get the best signal, and the disconnects have disappeared. When using the Iphone 3G, it works anywhere around my desk.
So, I will mark this message as solved since I'm pretty confident I found the issue.
Thanks,

Iphone 4 disconnects from Telus 3G network continuously while tethering

I have an iphone 4/iOS 4.1. I am in Canada subscribing to the Telus 3G cellular network. When tethering the iphone 4 to my notebook (WIFI turned off), the iphone simultaneously drops the tethering connection, drops the 3G connection and drops all bars on the strength indicator. It will stay disconnected for ~ 20 seconds then reconnect to the cellular network and re-establish the tethered connection. The iphone cycles through this series of events every 2 - 3 minutes indefinitely. It may take a few minutes to experience the first disconnect. I have had the same thing happen with 3 different iphone 4 units, all with iOS 4.1 on two different laptops, at 5 different cellular tower locations. This makes iphone 4 tethering on the Telus network all but unusable.
Has anyone else on the Telus network in Canada experienced this problem. If you haven't tried to tether the iphone to a computer and are on the Telus 3G network (without a WIFI connection in place)it would be greatly appreciated if you would try as per above and report back on your findings.
Thanks in advance,
Jim. . .

My brother in law has also the same problem. Bell say that many people have this problem. They have escalated the problem with Apple. For now they are telling us that we have to wait for the next IOS version. Hope it is going to be sooner than the 4.2 version due in november.
The problem look like that there is a timeout problem on the connection like if the connection is inactive for more than 10 second it disconnect. If I keep clicking and changing pages I have a lot less problems.
In the meantime, instead of opening a internet radio station to keep the connection alive (witch use a lot of bandwith) as suggested by Claveall, I tried a small application call "stayalive pro" that was developped to keep dial-up connections on. I setup the application to ping servers every 5 second. It seem to work so far and use a lot less bandwith than listening to internet radio. Just tested it for 5 minutes or so. Let me know if it work for you.
BTW, my earlier comment that it was not related to carrier, I just forgot that Bell and Telus are using the same 3G network.

Disconnecting while on Wireless Network

Hi
Some users raised issue for disconnection while accessing network via wireless. AP model - AIR-AP1131AG-E-K9. Cable connecting to AP is likely not an issue. what should be checked on the wireless lan controller to identify the issue
any comments will be appreciated
Thanks in advance

Network speed affected by large file copy operations. Also, why intermittent network outages?

Hi
I have a couple of issues on our company network.
The first is thate a single large file copy imapcts the entire network and dramatically reduces network speed and the second is that there are periodic outages where file open/close/save operations may appear to hang, and also where programs that rely on
network connectivity e.g. email, appear to hang. It is as though the PC loses it's connection to the network, but the status of the network icon does not change. For the second issue if we wait the program will respond but the wait period can be up to 1min.
The downside of this is that this affects Access databases on our server so that when an 'outage' occurs the Access client cannot recover and hangs permamnently.
We have a Windows Active Directory domain that comprises Windows 2003 R2 (soon to be decommissioned), Windows Server 2008 Standard and Windows Server 2012 R2 Standard domain controllers. There are two member servers: A file server running Windows 2008 Storage
Server and a remote access server (which also runs WSUS) running Windows Server 2012 Standard. The clients comprise about 35 Win7 PC's and 1 Vista PC.
When I copy or move a large file from the 2008 Storage Server to my Win7 client other staff experience massive slowdowns when accessing the network. Recently I was moving several files from the Storage Server to my local drive. The files comprised pairs
(e.g. folo76t5.pmm and folo76t5.pmi), one of which is less than 1MB and the other varies between 1.5 - 1.9GB. I was moving two files at a time so the total file size for each operation was just under 2GB.
While the file move operation was taking place a colleague was trying to open a 36k Excel file. After waiting 3mins he asked me for help. I did some tests and noticed that when I was not copying large files he could open the Excel file immediately. When
I started copying more data from the Storage Server to my local drive it took several minutes before his PC could open the Excel file.
I also noticed on my Win7 client that our email client (Pegasus Mail), which was the only application I had open at the time would hang when the move operation was started and it would take at least a minute for it to start responding.
Ordinarlily we work with many files
Anyone have any suggestions, please? This is something that is affecting all clients. I can't carry out file maintenance on large files during normal work hours if network speed is going to be so badly impacted.
I'm still working on the intermittent network outages (the second issue), but if anyone has any suggestions about what may be causing this I would be grateful if you could share them.
Thanks

What have you checked for resource usage during one of these copies of a large file?
At a minimum I would check Task Manager>Resource Monitor. In particular check the disk and network usage. Also, look at RAM and CPU while the copy is taking place.
What RAID level is there on the file server?
There are many possible areas that could be causing your problem(s). And it could be more than one thing. Start by checking these things. And go from there.
Hi, JohnB352
Thanks for the suggestions. I have monitored the server and can see that the memory is nearly maxed out with a lot of hard faults (varies between several hundred to several thousand), recorded during normal usage. The Disk and CPU seem normal.
I'm going to replace the RAM and double it up to 12GB.
Thanks! This may help with some other issues we are having. I'll post back after it has been done.
[Edit]
Forgot to mention: there are 6 drives in the server. 2 for the OS (Mirrored RAID 1) and 4 for the data (Striped RAID 5).

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

Is there any problem running again "bdls" after being disconnected while r

Hello
I have an emergecy question
Is there any problem running again "bdls" after being disconnected while running it (my network connecton to laptop got broken)
Thank you in advance

Hi,
Be sure that it does not continue to run. If it was really interrupted, yes, you must run it again. Otherwise you would have a lot of inconsistancies.

Playbook while tethered causing browser problems

I love my Playbook, but I've found that while tethered to my Bold 9700 and using the regular internet browser, that I can't seem to copy/paste or save an image from a website. It is also very jumpy while browsing. I do wait until the page is fully loaded and the blue status bar is done and gone, but it still won't function properly. I know this is a tethering issue because it has no problems while on wifi.
Does anyone else have this problem and have you found a solution...or is it a bug in the OS while tethered? If its a bug, I can live with that and just know that it might be corrected shortly.
Thanks!

are you on a 3g network or a 2g one?
good signal on phone?
densly populated area?
Tethering does not have the speed of wifi, but would be helpful to know the above questions.

I share your pain with same Intel WiFi Link 1000 bgn. After many, many hours yesterday I am now solidly running Wireless N at 144 Mbps on a LinkSys E4200, 99% reception from 30 feet away.
Previous to yesterday I could not get 'N' to work at all.
First, if you have a newer dual frequency Router, this Intel adapter only supports 2.4ghz..
1. I am using Access Connections 5.85, Windows 7
2. Router: 2.4 Ghz Network Mode: Mixed
3. On my LinkSys router Channel: Auto NEVER worked for either 'G' or 'N'. I picked channel 4 by chance and things got better. No further experiments.
3. Channel Width: Auto (20mhz or 40mhz).
4. Earlier forums indicate WPA2-P and AES must be selected. That's what I am running.
5. Numerous references to "power" conflicts. Set all Power Management to Maximum Power.
(Control Panel -> Device Manager ->Network Adapters -> Intel WiFi Link 1000 bgn -> Power Management)
(Access Connections -> Wireless Settings -> 4. Advanced Configuration-> Maximum Performance)
If you followed these steps, Wireless G should be working stabily for you now.
Now for the secret sauce to make Wireless N work: go to http://communities.intel.com/message/82098#82098
See Feb 3, 2010 post How to get 5100 AGN to connect at N speed?
I am indebted to this guy.
Save the instructions! For some reason my EDGE 14 wireless totally quit this week and that's what sent me down this wireless rabbit hole again. At least this time I was able to make N mode work for the first time.
Frustrated but relieved,

WRT54G V8 disconnects while downloading

I have a problem with my linksys router. It always seems to disconnect while i'm installing anything on my playstation. I can be streaming, playing online, or anything else but as soon as i update or install my linksys kicks out (yellow light off) and the download freezes. This only happens with my PS3, i have 2 other laptops that update or download just fine. Please Help!!!

You might be experiencing internet bottleneck which largely related to network congestion. This link might help: http://kb.linksys.com/Linksys/ukp.aspx?vw=1&docid=fbf8e8564632422eaa8ea80bf9dcba64_386.xml&pid=80&re...

"Network disconnected during sync."

We are getting a strange error
"ERROR",CNS-9107,"07/17/2006 12:03:40","Network disconnected during sync. "
while synchronizing our Oracle Lite PocketPC application with Mobile Server. This only seems to be happening when we are uploading inspections with photo data, have anyone else experienced this problem?

During the 'Sending' phase from the client, a packed binary file (created by the composing phase) is being uploaded to the server, where it is then unpacked and the data put into the in queues.
During 'recieving' the server is creating a packed binary download file from two main sources - the out queue data for the user, and real time queries for any complete refresh items.
Have you set trace logs to SYNC for an example user? This should tell you whether or not the read of the out queues or complete refresh queries are at fault (you should see a list of publication items, and then the trace for each one in turn as it is processed). If the log shows that it is stopping on one publication item (normally a complete refresh), particularly where you have a long download time, then the query may be timing out.
If the sync log shows that all PI's have been processed successfully, then the problem is probably related to the send of the packed binary file. Have a look at the sync history for the user, in terms of record and byte count downloaded - is this excessive? Publication items containing BLOB columns (like images) set to complete refresh could be very large
On the client you should find a file(s) <USERNAME>olres.bin and/or <USERNAME>_olres.bin If you find them, the download at least started. When you say that the user cannot re-sync, do you mean that they get the same error reported? if so try deleting these files and see what happens (a server side error will be within the download file so will not go away until you kill the failed download files), if you still get the error quickly after removing the files, something has broken the activesync connection. If re-cradling the Pocket PC device to re-establish the connection works, then the problem is definitely in the activesync set up.. If it does not, is there anything in your network software that is restricting file downloads or packets?

Why is the network disconnecting since downloading leopard os on my mac

Why is the network disconnecting since downloading lion10.7.2 ?
Message was edited by: Jimfromtx

Just corrected leopard to lion. I connect wirelessly to my router. Shows as connected in taskbar but isn't until I go to network settings and reconnect. Then will stay connected while I am using. When I leave computer alone for 30 minutes or so and return have to do reconnect process all over.

RFS[2647]: Possible network disconnect with primary database

Hi Guys,
I am working as a L1 DBA in my project. We have a 3node RAC database 11.2.0.1.0 and the standby database was in sink with production till yesterday. Suddenly we realized that out primary and standby is not in sink.. Logs are shipped from primary but it is not applying in standby. While checking the alertlog I can see these errors.

I have performed a media recovery but still I am facing the above errors. I thought earlier that there might be some network issue but we can ping the service names from both the primary and standby.
Can you please suggest me the steps that I can go through and fix this issue.

ARCH: Possible network disconnect with primary database

Dear buddies,
My database has a primary database which has a few sub databases.
They are in different servers.
One of the sub database has this error in the alert log everyday during backup time.
But finally the backup is successful.
Is this a network problem?
Please guide me.
Thanks in advance.

Network disconnectivity caused application services to hang, why?

Hi
We have single node installation of R12.0.6 on IBM server. When there was network disconnectivity from domain server, application server services were hanging, why? Tried to bounce apps tier services, but timed-out. Had to reboot the server for fixing the problem.
What caused application to hang when there was no network? How to trouble shoot network issues in R12i?
