Toshiba Satellite AA665D-s6091 - High Latency Due To Network And Wireless Adapters
Mar 18, 2012
I have the same issue with Toshiba satellite AA665D-s6091 I expierience crackling sound when playing. peaks appeared when I had either the (cable and wireless) adaptors enabled, when I enable/disable the backlit keyboard and also when I enable/disable eco-mode.A Windows and driver update fixed the cable adaptor issue.
I ran the commands in post #19:
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global congestionprovider=ctcp
netsh int tcp set global dca=enabled
The wireless adaptor issue was fixed with these, however every time y enable/disable backlit keyboard or eco-mode on my laptop I still get this latency peaks around 18000 us and audio clicks. I check latency with DPC latency checker V1.3.0?

When using this laptop (Toshiba Satellite C660D-1GD) on the forum it seemed unusually laggy when changing pages, whereas when using my Toshiba Satellite L450D it is always more positive.Decided to do some ping tests via the cmd prompt (after checking the error count via telnet) and they were in the hundreds.The L450D ping tests are spot on so I know it isn't the router (Billion Bipac 7800N)Been the usual route, totally uninstalled the wireless adaptor (Realtek RTL8188CE Wireless LAN 802.11n) including the Cisco elements, Eset and MBAM full scan and downloaded chipset drivers. Even factory reset the router and deleted the wireless profile including reg entries as a last resort.After each of those operations (other than reinstalling the wireless adaptor) the latency would be spot on and continued to be after an immediate reboot, but logging on a couple of hours later or the following morning, they would be very high again.After reinstalling the wireless adaptor for the second time, on a hunch I removed the Ethernet cable and run another test. The latency came in high but when I re-ran the test wired, they were spot on.
Phoned up KnowHow techs and read off the numbers who then put me onto 2nd level tech. He remotely connected and ran a couple of ping -n 50 tests as well as a tracert but was unable to replicate the results I was gettiing. As nothing was broken (for him), nothing to fix but to phone again if it continued.I rebooted after the phone call and got the high latency straight off. I wondered, as the latency returned to normal after certain operations I'd done, whether the remote connection had the same effect.Having been on the phone for 55mins, I'd had enough.These are two tests I've recorded from today which are together in one Wordpad doc, so you'll be able to see what I mean. Ctrl+C has been a bit erratic so they are the only ones I've been able to save. [code]

my latency values are extremely high, sometimes millions(!) of microseconds. THe problem is always solved by disconnecting the 11b/g wireless LAN adapter, or the Intel(R) Gigabit Network connection. However, I can't work without internet.

i have a Toshiba Satellite A215 with Windows Vista Home Premium. The laptop has been running on my wireless network for several years with no issues. For some reason I can no longer access the wireless network/Internet but can through the LAN (cable). I have other 2 other computers (Dell desktop and iPad) that are running on the wireless network so it just seems to be the Toshiba laptop that is having the problem. I have not done anything new to the network router or the Toshiba and am not sure why the Toshiba all of a sudden no longer does not have wireless access. The devise manager says the adapter is functioning properly. I have looked at other resolved issues on your site that have had this issue but have not been able to resolve my issue. As requested with other similar issues here is the ipconfig for the Toshiba.

I recently reformatted the hard drive and when I finished I tried to connect to our home network and the laptop will not. The wireless is on, the network shows up, I click connect, put in the password, but it keeps coming up that it cannot connect. When I click diagnose, it reads that I can either try reconnecting to the network or reset the wireless router/access point and try again. We have a desktop connected, 2 laptops, & TiVo with no problems. This is the only laptop that has a problem. Yesterday I reformatted another Toshiba laptop's hard drive and had no trouble reconnecting to the home network. I've read several threads regarding this matter, and have tried the following:
(1) TCP/IP stack repair options for use with Windows Vista - nothing looked unusual with each step, and (2) ipconfig /all - attaching the txt file with results.
I am at a loss. I don't want to hard wire it as the last time I did this, the internet was lost on all of out devices and it took me a day to get it back to the way it was.

So I have a Toshiba Satellite L555D-S7005. When I put it into Hibernate mode (I dont like turning it off, takes too much time) it paralyzes my whole wireless network. It makes it so that anybody else on WIRELESS gets disconnected, and cannot reconnect easily (they must restart the router). This gets very irritating when my brother is on the X-BOX/Laptop and he cannot continue playing games or whatever. If I disconnect my laptop the network goes down for them, but not for me. I can log right back on and connect with no problems. The wired computer has no problems with internet when I turn off my laptop.

My Toshiba Satellite Pro laptop has suddenly stopped detecting my wireless network. IT detects every other network in the area but mine. Other computers in the house have no problem detecting and connecting.Wireless is enabled, it happens no matter how close or far from the router. The network is set to broadcast the ssid, etc. I have not changed any settings on my laptop or router, this has suddenly started happening. Have updated drivers to no effect.Occasionally, the network pops up when I re-start the laptop. Rarely works and sometimes it will detect the network, then fail to connect, then the network can't be detected at all.

Since yesterday evening, my Toshiba Satellite Laptop (L505D-ES5025) hasn't been able to register my wireless network, though it registered it perfectly fine yesterday morning. I can only detect the local area connection, and can only connect to the internet via the ethernet cable (which is what I'm using right now).Even when I go to the "Change Adapter Settings" from Control Panel, it won't detect the wireless network that I use. The other computers/laptops in the house work, but this one can't regiester to it, even though it's the closest to the router. When I troubleshoot the problem, the only solution is to use the ethernet cable, but I can't depend on it since the whole point of using a wireless connection is to go wireless.I have tried the Control Panel solution of going to the device manager, but I can't find the wireless network from there. This Toshiba computer also doesn't have a physical WLAN button; rather hot keys are used (though when I use this, it doesn't anyways).I also tried to find the drivers for it to update, but those won't either update, or they do update but nothing happens. In other words, I can't do anything because my laptop can't find ANY networks whatsoever except for the one that is found after I connect it to the ethernet cable.My OS is Windows 7, 64-bit Home Premium.

\We have purchased AP 1041 and WLC 2500 and I am doing a testing on the configuration. It is fine when both AP and WLC are sitting on the same network. However, if I connect the AP to the WLC which is on another network, I found that latency is quite high when PING the gateway. Here is the brief topology.
AP (172.30.40.212) ------- (VLAN 1: 172.30.40.202) switch (VLAN 2: 172.30.41.202) ----------- (172.30.41.210) WLC
I try to plug the PC to VLAN 1 and do a PING test to the VLAN 1 interface and it causes some packet loss and high latency. [URL] If I do the debug ip udp on the AP, it seems the result is normal.
*May 28 13:53:36.951: UDP: sent src=172.30.40.212(26610), dst=172.30.41.210(5246), length=1069
*May 28 13:53:36.952: UDP: rcvd src=172.30.41.210(5246), dst=172.30.40.212(26610), length=89
*May 28 13:53:36.953: UDP: sent src=172.30.40.212(26610), dst=172.30.41.210(5246), length=685
*May 28 13:53:36.954: UDP: rcvd src=172.30.41.210(5246), dst=172.30.40.212(26610), length=89
Configuration:
AP 1041 Version: 15.2(2)JB
WLC 2500 version: 7.4.100.0
Both device are configured the static IP address manually with default setting and I do not enable DHCP option 43.

i have a home network my dell netbook and dell xps desktop are connected to it, both are able to connect to the internet, my toshiba satellite for some reason won't connect. i think the wifi radio isn't working because there is an icon on the front of the lapptop with a picture of a wifi transmitter, and the amber light is lit for that. my router won't recognize it and neither will the other computers. it was working just fine to connect to the internet before i set the network up with the other two computers. the toshiba is the only one that has windows 7 btw, the others one has vista and one has xp. don't know if this has anything to do with it, but im stumped. i trtied to do it manually, but the router keeps saying the mac address is invalid, i get that from ip config.

I have a new toshiba satellite laptop and it won't access my wireless network. It says unknown public network and refuses access. I have no problems using ethernet. All other computers in household access fine. One day it worked and one day it didnt. I have tried to start over with new network and add the security key again and it still refuses to access the network.

Recently me and my girlfriend have been having issues with in game latency, receiving pings close to jittering to well over 300 where they were formerly in the 30-40s to identical servers. We live with a Chinese housemate who is extremely conscious of her privacy/personal space, we noticed a dirge of active ports on the router (both TCP and UDP) which seemed to have no association with any major application and assumed it was the old P2P boogie-monster. She is the only one who uses Wifi, an upon briefly deactivating the Wifi, all ping issues were instantly resolved. The bizarre thing is we still have plently of up/download bandwidth, I mean we're not swimming in a fibre optic connection but still a relatively healthy 1MB dl/70KB/s ul, more than enough for gaming.Deciding we needed a better idea of what was going on in the network, we downloaded Wireshark. We discovered a couple of things that might mean something, they might mean nothing at all:Firstly there was a deluge of random ARP requests coming from the suspect IP, something along the lines of:"who has 192.168.0.(random number) Tell (suspect computer's IP)"repeated over and over in bursts. A little googling found us this: Has Your Network been Now given that she is Chinese and is probably exposed to a lot of Chinese websites, is there any chance that this could be the root cause - could it drown the network to the extent that it produces terrible pings?Secondly there have been an inordinate amount of name queries coming from her IP to 192.168.0.255 (broadcast channel), they generally take the form of:
NBNS92Name query NB WPAD<00>
or
NBNS92Name query NB ISATAP<00>
and occasionally, it will name query my network id, leading to: (her ip being 192.168.0.3)
2144211275.734470000192.168.0.3 192.168.0.255NBNS92Name query NB (my id)<20>
2144231275.739314000192.168.0.3 (my id)TCP6658451 > netbios-ssn [SYN] Seq=0 Win=8192 Len=0 MSS=1460 WS=4 SACK_PERM=1
2144251275.741325000192.168.0.3 (my id)NBSS126Session request, to (my network id)<20> from (her network id)<00>
2144271275.744124000192.168.0.3 (my id)SMB213Negotiate Protocol Request
[code]....
Now combine this with the sometimes 9-10 active ports our router assigns to her IP (which don't appear to relate to anything according to numerous port id sites), does this send out a red flag to any of you? I realize it would be so much easier if I could get access to her computer, but as I said, she is very private and timid and doesn't seem to like even having people in her room, let alone letting them use her computer.

I have a WRT54G2 router (V1) with the most recent firmware that serves as the gateway between my Internet connection and my home network. Over the past few months, I've noticed that the router seems to consistently become unusable due to high latency when it runs for any period of time. The internet connection is working, but the latency is sometimes as high as 2000ms to ping Google or to run a test from Speedtest.net. When a computer is directly plugged into the cable modem provided by my ISP, the problems resolve.
Restarting the router proivdes a resolution of the problem, but over time the latency issues increase again until it needs to be restarted. Right now, I have it on a mechanical (plug) timer that restarts it every morning around 4AM, but this still doesn't seem to fix the overall issue; I've had to restart the router manually twice today. Before restart, my ping will be over 1000ms; afterward, it will drop back to 20-60ms.Note that the download and upload speeds don't seem to be affected by this, just the latency itself.
The problem appears on both wireless and wired connections.I'm not sure if this is a sign that our router is failing (it was purchased in 2009, so as far as consumer-grade solutions go, it's lasted a pretty decent span), or if there's some misconfiguration on my end, or if something with my ISP is making my router flip out. What can/should I do to fix this issue (please note that flashing the router with DD-WRT is not an option, this version generally sees decreased performance when DD-WRT is installed).EDITED TO ADD: I have ruled out internal traffic causing the problem (I reviewed the log files for the router and tried to identify any unknown stuff, but it seems fine). I can't quite figure out exactly what causes the router to develop the issue, but once it does, I've noticed the following:
Extremely high latency (1000ms+) for pings from any computer inside the network to an outside destination?The router itself cannot ping or traceroute once it has started developing these high latency issues - if you use the router's PING feature, it returns all timeouts.It does not seem to correlate with any specific type of traffic.

I work for a small college. We have several Cisco 1200 Aironet deployed our the campus, all of which are configures to run multiple SSID's. The problem I have is that when I connect, via AP, it successfully connects to the desired SSID but on pinging the default gateway of said SSID I get high latency (avg around 100 - 200ms).When pinging from the switch (Cisco 2950) to the default gateway the latency is good (1-2ms). It is just high when I connect via the C1200 AP and try to ping.

I can't turn WI-FI on in my Toshiba A 665, Win 7. At the biginning worked good ,than vanished. Checking Fn > F8 below main icon (with an antena ) do not show up other four icons below, like they suppose to do. So I'm not even able to try to turn it on. Restarting doesn't do at all. Pushing Wi-fi switch, above the keybord, doesn't even show On/of icon.

I can connect to my wireless with my cellphone, so it might be a problem with the laptop.And I can connect to the internet with the cable. It's just the wireless that doesn't work.

I am using a toshiba satellite and have accessed the router through another computer and was able to access the internet. I am currently using the ipad to post.At first when i choose my internet connection, it will automativally try and detect the network type, then tell me that "windows is unable to connect to the selected network". I have read other user posts and went to the wireless properties and changed the network authentication to shared and unclicked the "key index". Now, when i click on my wireless network it will automatically ask me to enter my network key. But after i do that, all it does is wait a few seconds and close that dialog box without connecting me.[code]

My Toshiba Satellite (C655-S5049) with Atheros wireless works just fine at my home and a number of public wireless locations (Panara Bread, libraries, school, etc.) There are many other public wireless locations where I try to connect and just get an "unable to connect" dialog box which gives me the options to "diagnose connection problem" (blames the access point). The places that work, work consistently. The places that don't work, I've never been able to get in even though people around me are online with their machines.I'm running thie machine pretty much as it was delivered out of the box. I've installed AVG for virus protection, and I have all the default protection settings (firewall, sharing, etc.).
