Satellite Z830 - Wireless adapter drop out/conflict with USB

My Satellite Z830 has a wierd problem. The wireless connectivity works well until I plug a usb flashdrive into the usb 3 port on the side. The wireless then drops out after a period and from then on it cant find any wireless connections available. It effectively kills the wireless adapter, or at least makes it less reliable.
You have to reboot to get the connection back. I've tried with a few different usb storage devices with the same outcome. Both the wireless connection and the usb drive work fine, but not at the same time. This happens regardless of whether using the battery or when plugged in. I checked the power settings to ensure there wasnt some problem there. Everything is just on factory install/settings generally, so I cant imagine it is anything I've changed.
I'm at work, but I'll see if I have the same problem with the usb sockets at the back, and/or with powered usb hard disk, when i get home. This is really annoying, as you cant use the net and leave a usb disk in without risking a drop out. I havent checked messing around with USB root hub settings or IRC issues as this seems unlikely. Any thoughts or is the a "give it back to Toshiba" issue - I'd rather not have the down time. It took me quite a while to work out this was the problem.
The wireless connection itself is very strong where the ultrabook is being used, so isnt a signal strength issue.

I used inSSIDer Office 5 day trial (http://www.metageek.net/support/downloads/)
too identify the same problem with my Z830.
_The results are really astonishing:_
the signal strength measured in dBm increases by > 100 times when the corded mouse is unplugged from the from the side USB port.
(plugging it into any of the USB ports in the back has no impact on the signal strength.)
In my case it jumped from -68 dBm to -41 dBm,: the -27 dBm difference means a 22.4 times improvement in signal strength (from about 100 pW to 2,240 pW).
See wikipedia for signal strength calculations: http://en.wikipedia.org/wiki/DBm
I tested to plug in an external hard disk into the side USB and it had the same -27 dBm effect on the signal strength.
In other words the wifi signal strength jumps from poor to excellent when the side USB is not used.
Toshiba must look into this significant hardware design fault and in the interim, as the very least, must advise their customers against using the side USB port when on a wireless network.

Wireless keeps dropping out

The wireless was working fine, i had it working with network-manager i then was doing some work that i wanted to do via ethernet so switched the wireless off using the switch and now it keeps dropping out, i have had to remove network-manager as it wouldnt let me connect to wired for some reason, and have tried to get wireless re-working with wifi-menu, i have delected the config and created one using the examples and using netcfg and still having no luck. I looks as if the device is going into "power saving" and wont come out, outputs below:

Time Capsule wireless intermittent drop outs to PC and iPhone

I have a Time Capsule that we use in our home as a wireless router and back-up. It is connected to a Comcast cable modem only. It has worked well, but about a couple months ago we started to have issues. Our iMac sees the Time Capsule through the wireless fine and has no connectivity issues. However, my PC laptop, that used to connect wirelessly, now has issues keeping a connection and so does my iPhone. The two devices will see the network and connect, but the connection drops out after a minute or so, then reconnects, and the cycle continues. I am not sure what to do to fix this and it makes me even more confused since our iMac has no issues with the wireless connection. Has anyone experienced this issue? Thanks!

All that is Ok, and TIvo says I am hooked up correctly. THey say this is the problem, they can look at the box to see the error #.
The following ports (whether inbound or outbound) must be open to allow your TiVo box to communicate with the TiVo Servers, other TiVo boxes, and your Macintosh or Windows PC:
TCP port 37
TCP port 80
TCP port 443
TCP port 2190

Wireless connection drops out for no reason

I have a macbook with 10.4.11 update. I had my macbook since october last year and had no problems. About two months ago now i have this problem were my wireless connection drops for no reason, my modem/router shows everything is working normal with its lights on the front panel.
My setup is, motorola sbg900 on a cable 80000mbps wireless network, firewall off on my modem, firewall on on my mac (its always been on), Playstation 3(wireless), PC(wireless, but is switched off), another pc which is wireless and also off, nintendo wii off as well, and a baby monitor.
I have a feeling its nothing to do with my setup(except for maybe port forwarding) but am wondering if it is an update issue bug that needs to be fixed(thats what im hoping).
One other thing, when my connection drops in the menu bar and i select it to see which networks are availale, my network motorola8566 is not visible, another 'motorola9522' and 'wireless' network is?My prefered networks dont list any of these in system preferences. Then all of a sudden those other networks dissapear, my network is reshown and i can select it no propblems. What gives? Any help would be great, thanx in advandce

I have the same issue with my wireless connection being dropped. I have the most recent version of leopard 10.5.2 . The other macbook in this household also has 10.5.2 and has no problems with dropped connections. I tried resetting the pram which helped at first until I used my macbook on the battery alone the problem started to reoccur. Help?!?

WRT45G wireless internet dropping out

Hey there,
Hoping someone can help me out here with perhaps an option change in the router settings or what not.
Here's the issue, I will have the router up and running with two laptops and an Iphone connected through wireless.
The connection will show still connected but I will have no internet connection. I haven't tried this wired yet. The only way I can resolve it is reseting the router on the back, restoring it to factory default. Which resets password, mac filter and all that jazz.
Can someone help me out? this happens at least twice a day.

Well you should try with the wired connection first....because if does the same thing with the wired connection as well then it could be a firmware issue ,
Anyhow , as per as the wireless is concern it says connected but you are not online.....check what ipaddress that you are getting at that time .

Satellite L50Dt-A: WLan drops out or shows "limited" connection

My wireless internet connection is was fine until last week - now it regularly drops out or shows "limited" connection.
Other computers including an ipad and printer are on the same connection but are not experiencing the same problems as my new Toshiba
Can anyone assist please?

Hi
What windows system do you have?
Did you update the system probably from Win 8 to Win 8.1?
Did you try to update the Wlan driver?
If not do that!
Mostly such symptoms could be solved by new WLan driver reinstallation or update.

Why does my iMac wireless keep dropping out?

My iMac wi-fi keeps dropping out intermittently. Sometimes, I can trace it to the router, but sometimes, everything else stays connected to the router, and only my iMac drops out. I can check 'speed test' app in my iPhone4s through the router and it is still working and connected, but the iMac has dropped off. It usually will connect back up, but sometimes takes 2 tries to get the job done. It is starting to get annoying in frequency.
The iMac is about 1 year old now. This has been happening recently. I suspect trouble in my airport extreme card, but don't know how to check it out.
Any ideas?
Thanks!
Jim

never mind. I went to apple care support and after deleting some plists, resetting the computer a few times and a few other tricks, it is working well again.
But to answer your questions: airport monitor of computer. I have a Cisco router. The iPhone was using internet and the speed test app showed normal connections and speed.
Thanks for your interest,
Jim

Satellite Pro L20 doesn't work properly with USB Fast Track audio i.f.

Hello!
I have used my Fast Track USB on new Toshiba Satellite L40 and I never had problems with it. I could set low latency and I did few songs with it.
Yesterday I bought another notebook, thinking of home recording studio. It's used Toshiba Satellite Pro L20. It doesn't work properly with my interface. When I listen music on Winamp or do anything on Fruity Loops I hear loud clicks, pops, noises. They introduce samples, or they appear during playback or after a sample is stopped.
I noticed, drivers for Satellite Pro L20 are a problem. Its not supported by Toshiba anymore?! The only drivers for chipset are very old and you can download em only from Toshiba website. The chipset is ATI Xpress 200M. Its drivers are with graphic card. Recently I noticed you can download "ATI Catalyst Legacy Display Driver for Windows XP - Motherboard/IGP Drivers 9.11" and CRACK IT to make it possible to install on mobile unit such as L20. Yep its funny but its impossible to do otherwise!
things I have tried and they still not help:
# drivers replacement, original were released in 2004. I installed recent version.
# driver settings, low latency, high latency
# asio and different settings
# pluging the interface to another usb socket.
# trying what happens when I use battery and when I use adapter
# updated bios
# turned off onboard units such as wifi card, sound card
# checked IRQ list
pops still appear.
my config:
Toshiba Satellite Pro L20
Win XP Home SP3
Celeron M 1,5GHz
896Mb ram
M-Audio Fast Track USB, drivers: 6.0.2
Kind regards

Thanks for answer. I still have L40 but I try to run my homerecording on L20. The L40 is now used by whole my family. It's possible to swap them but there's a problem - L20 has Norway keyboard and I'm the only person at home who doesn't often look down while typing. In Poland, we use standard ms keyboard. I'd buy special stickers, it's about only to make special chars get back to their places.
I installed Windows on this computer end set it to best performance possible.
Since I created this thread, guys from M-Audio support tried to solve my problem - nothing helped. I think potential solutions are exhausted.

My wireless computers drop out and can't see WRT54G.

Hello, I have a problem with my WRT54G. It has not been upgraded as far as firmware. I took a wireless class two semesters ago and I got a linksys WRT54G, it had the best results. I have a laptop and 2 pcs. My first pc. where my cable modem is, is hooked up to the WRT54G via Ethernet cable. The other two computers connect wirlessly. The last few days my router has been dis connecting them and when they try to connect to it, they can't even see it. Eventually I just keep reseting it till I find it again. It usually happens when My cable modem stops receiving information from the router. I power down the router for about 6 seconds to fix the sending information problem, but once it comes back up, my laptop and pc can no longer associate to it. So, I spend more time trying to repair it, reseting it, and such. Eventually it works but it happens the next day and I have to do it all over again. It is getting very tedious. My pc, the one that is hard wired, never has problems. Only wireless, which means It's something to do with the wireless settings. I know you are going to say upgrade the firmware, but I tried many times and it always fails for some reason. Any ideas?

I too have a WRT54G That I have to reset more often then I care. I have 6 computers that connect and a VoIP phone. I run fine all day long until the kids come home. Once they get on their computers the Cisco Systems light on my router will go out and everything goes dead. I reset the router and I am fine but I may go back down until I just unplug them. During the day I am using the VoIP phone, using Net Meeting and Goto Meeting all while up and down loading files without any problem. I have enabled QoS and even set priority on port. They still kill me. I too loose my network connection to my DSL Modem.
I am using Firmware version 1.02.2. I need to get this resolved before they get out of school or it will be a very long summer.

Ichat dropping out issue with Broadband Tuner?

All,
I posted before when I was having this issue and Ralph suggested that since I had a FIOS connection and OS 10.3 I limit my bandwith to 100 in video preferences. That fix works(thanks Ralph), although my image is not as crisp.
Now I have 10.5.2 and downloaded the Broadband Tuner. Still have issue with Ichat just breaking down (running connection doctor show audio and video dropping off). I was wondering if I maybe need to do something else besides just install the Tuner? It came up with a successful install, but it seems like it is doing nothing?
Any help would be appreciated.
Jon

Hi Jon,
I see it says not for Airports at the bottom
http://www.apple.com/support/downloads/broadbandtuner10.html
I don't know if this effect you.
I am not sure where to look on a Mac to find out if it is working or not.
I would recheck the Bandwidth option in iChat to see which works best for your try anything up to 500kbps.
Do you know if your Connection speed is varying greatly ?
This is the normal issue with FiOS.

Anyone else having wifi drop out issues with their iPad 3?

Right from the word 'go' I have experienced frequent losses in wifi connectivity on my iPad 3 (64Gb, 4G). Fortunately I don't have to keep re-entering my wifi password but I do have to keep renewing the lease which is really tedious. My iPad 2 works flawlessly on the same network (Netgear cable modem/router from Virginmedia). I also have an iPod Touch and an iPhone that also work without issues on this set up. Thus far I have tried:
Rebooting the modem
Restoring the iPad 3
Resetting the network settings on the iPad 3
Changing the channel on the router from 'auto' to various other channels
Switching between WPA and WEP encryption on the router
Turning off the auto brightness (a tip I saw that worked on some of the earlier iPads)
None of the above have helped and after three calls to Apple support I have received a replacement iPad 3 which has exactly the same problem? People talk about replacing one's router as a potential solution but my options are limited because this is a combination cable unit supplied by Virginmedia. Also, the issue points pretty clearly to the iPad 3 because, as I mention, my other Apple products work flawlessly. I'm going abroad shortly and I'm thinking of leaving the iPad 3 at home if I can't sort out its wifi capabilities.
Any ideas?

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
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.
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.

It is not easy to explain why this happen but there can be many responsible
for this. It can happen if between notebook and router is a long way.

Wireless network drops out on one MBP, not the other

I have two Macbook Pros as part of a wireless network (Extreme/Express 802.11g). Lately the older of the MBPs (2.16 Core Duo) keeps losing the connection and won't recognize the network. If I restart the Airport Extreme and my modem and the MBP it will sometimes come back. Meanwhile my brand new MBP never loses the connection.
Anybody have any suggestions on where I can start looking or what I can start adjusting to eliminate this problem? Please don't hesitate to let me know if there's other info I can provide to help solve this.
Thanks in advance.

If you place the two MBPs side by side for a few hours, does the older device still lose the wireless signal while newer one remains connected?
If yes, then you may have a wireless card that is starting to act up or the internal antenna connector may be making intermittent contact. A repair shop will need to check things out.
If no, then you're likely picking up some form of wireless interference in the area where the older MBP is normally located. The usual culprits are a cordless phone (sometimes at the neighbors) and nearby wireless networks. Post back for a few suggestions on this.

Safari drops out often with ipad1

Why does safari crash so often, am having trouble using Facebook

Usually it's because you are not connecting to the internet via wifi.

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.
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
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.
