Realtek Rtl8190 Wifi Connection Breaks Sometimes When A Session Is Started
Jun 17, 2012
I have had intermittent problems with this PCI 802.11n adapter since I installed it. There isn't a new driver available, so that's not a solution. Issue is despite a strong signal, WiFi connection breaks sometimes when a session (either e-mail or browser) is started.The bar signal indicator goes from 5 bars to none, and mouse-over shows "no connection." About half the time the PC locks up (frozen cursor, no response to ctrl-alt-del, etc.).some of the time, the PC recovers after several minutes or more, other times locks up completely and the PC must be either forced reset or powered down manually. I've run CC Cleaner and check out the registry but can't find anything that works. PC is a 2.4GHz Celeron 1GB RAM running WinXP SP3 with all updates.Not related to browser; behavior is the same with Firefox, Chrome, IE. Also, other PCs on same network have no issues.On occasion I've triggered the lock-up while I had performance monitor running, and in the cases where the machine resumed running by itself, history showed no overloads typical of lock-ups. This PC is used almost exclusively for basic e-mail and browsing.

I using cisco 837 for incoming remote access VPN connections with are working very well but I recently created one outgoing easy vpn connection and I have issue since that time. As soon as easy VPN is up and established successfully I lost remote VPN access to internal subnet.
Where is :
Internal subnet: 192.168.172.0/24
remote VPN pool 192.168.24.2-6
Take a look at config attached and point me at missconfiguration

I have 3 computers at my home, a WRT54G V1 router.
2 of the computers are connected wired to the router, the internet on them works fine. My other computer I have connected via wireless, and when I try to go on the internet every 3 seconds it is saying not available. Now one thing I noticed was that when I connected to the wireless network it renamed it to my computers service tag. I confirmed this via a friends laptop. From "Busted" to "DCLZMRH1_Network", defenetly not something I did.
When this wireless computer is connected, ALL computers on the network begin having the same problem where each 3 seconds everybody is disconnected randomly. However as soon as I turn the wireless computer off, everything goes back to normal on the wired computers.
I have successfuly replicated this issue using 2 different wireless adapters, one USB, and one "wired" the one you put on the inside (lol) I have Brighthouse Networks cable internet

I have an ancient Compaq V2410 notebook which has started to drop my home Wifi connection recently (started about a week ago). At first, I thought it was the install of Firefox 8 as it froze and crashed but it happens with Chrome, IE and even when not running a browser.
My ISP is O2 in the UK and I have a DSL2+ service with the O2 Wireless Box II. I have gone through a power down cycle on the router and it continues to work with my ethernet-connected desktop PC. I have changed the Wireless Card in the notebook but fault is still intermittent. The notebook was also set to OpenDNS servers but that has been set back to Automatic DNS servers.
The notebook has the latest free versions of Avast Anti-virus & Comodo Firewall and the main issue is that the notebook has 640Mb system RAM which means that various Windows services have been Disabled or set to Manual.
I can sometimes recover the Wifi signal by switching the wireless on/off but it is sporadic. I have attached the Xirrus WiFi screenshots at startup, at fault state and at recovery state together with the ipconfig.txt output.

I am running an ASUS laptop with Windows 7. My wireless has been working fine, but my room is quite far from the router, so I bought a signal-booster USB aerial made by Realtek (REALTEK 11n USB Wireless LAN Driver and Utility). It came with a small software CD too which I installed, and it worked fine for two days and boosted my wireless signal.However (you knew it was coming, the story can't stay happy) soon the red light on the USB booster stopped blinking and it showed the red 'x' where my wifi connections are. I couldn't get it to re-establish a connection without doing a full system restore and re-installing the USB signal booster, which would then work again for a short amount of time (maybe a day, maybe an hour). And worse, now when the USB booster is unplugged from the computer my laptop will not return to recognising wireless connections like it did before I installed the USB signal booster. It simply does not find any connections - the only time it does is directly after I have re-installed the software from the small disc which came with the Realtek USB signal booster.
I have now uninstalled the Software and anything made by Realtek but still it is finding no connections.Now I would just like to find a way to get back to where I started when my computer was finding all wireless connections like normal... a connection with a weak signal is better than this nightmare of constantly restoring my computer just to get a brief connection

I have been using a linksys 5 port workgroup switch in my room. I have the ethernet cable coming from the router into the uplink port and my PS3, xbox, dvr, and pc in the other ports. It has been working fine until today I started messing around the the cables. I had trouble with the ps3 connecting to the internet so I used my laptop with wifi disabled to test out a few of the cables and ports. Now all of a sudden the switch kills the internet connection. If I remove the cable running to my room from the main router, the other PCs and wireless will connect, but as soon I plug myself up it goes dead. I now have the ethernet cable in my room hooked directly to the PC bypassing the switch and everything works fine now.

Recently, i bought a LinkSys WAG120N ANNEX-A to replace my old speedstrem4200. Well everything was fine, but after 2 days of it installed, it started to drop my ADSL connection.
Sometimes, it remain connected for 4-5 hours, then drop, or sometimes, it drop every 30min-1hour.I tried upgrading the firmware to 1.00.16, but no luck, it still drop the connection.I have 3 computer plugged to the router via cable(wired) plus 1 netbook(wireless) and 1 ipod (wireless).Sometimes, when 1 computer is turned off, it seem to make the ADSL connection drop when the LAN light turn off. I noticed everytime it drop the ADSL connection, in the logs, i get this:

I tried changing the MTU settings in the router to 1492 (my ISP default) but didnt work.
Tried changing the MTU to 1492 on every computer and still got the same problem.For now im using the WAG120N in bridge mode, and still using my old speedstream4200 as ADSL modem.

So I bought this new E4200v1 about a week ago and since yesterday it started dropping connection terribly. After checking Cisco Connect it seemed to have a Firmware update which I did and after it was done I decided to do a factory reset since I read somewhere that it works. When the router came back on for a second I saw an unsecured SSID, but then it turned into an SSID called panelist-ssid with a password called google-4panel which is definitely not the default. Also, when I try to access the router webpage to configure it, the password is not the old one nor the default Username: blank Password: admin credentials. I am currently connected to it via the button on the back that allows me to connect without password. Another thing is that I uninstalled Cisco Connect and when I try to install at 25% it says it cannot find my router and ask for SSID + password which I input yet it fails.

Not sure where the best place to drop this question. It is a DIR-601 router. I have it configured in the virtual servers list as; internal system ip, public port/private port both 23, protocal tcp with inbound filter, allow all and schedule set to always. I have a second system with a different public port. I can connect to either one but after a short amount of idle time it appears to just drop the connection.

I have a big problem with my Cisco 1841 and the WIC-1AM-V2 in Slot 0.I got the task, to test if it is possible, to build up a connection (Dial on Demand Routing) to a remote modem, which is connected to a console port of another Cisco 1841, with the integrated modem card over POTS from the CLI of the router. My router will only dial out to the remote modems and only if its needed.I am connected to the router with the integrated modem card over a console cable on the console port. The remote modem is also connected to the console port of the remote Cisco 1841.
I found out, with my Dialer Profile configuration, it is possible to build up a connection. I configured a dialer list, that specifies that all ip traffic is permitted an interesting for my dialer interface. So a telnet or ping brings up my dialer, which brings up my Async interface. With the "show line" command, I can see that the TTY line, connected with the Async0/0/0 Interface is in use for 5 minutes, because of the "exec-timeout 5 0", which is configured on the remote router. Now the problem is, in this 5 minutes, I can not use a remote telnet on this line with my loopback interface, because the line is already in use and I get a "connection refused". The first telnet I use runs in a timeout, because the remote host is not responding. When I dial out directly from the modem card and not from the CLI with the AT-commands, I get also the connection and with a return i get the login prompt. I will post my actual config, so that you can see maybe a mistake I did or which command I must use, to get a working connection. [code]

When a client connecting to a specific AP (example AP01), after every 1800 sec uptime it will reconnect and join other unit AP (example AP02)Both AP physically installed distance is around 6 meters from each other. I conduct the testing where i get myself sitting in middle between these two APs.
01. If i disable settsion timeout this feature, or setting the seconds become higher value, what's the performance and security impact? Is it recomend to change the default 1800 seconds session timeout?
02. Is there anyway i can tweak on WLC controller to prevent the client after session timeout then associate with another AP. This will lead major performance impact as the client woudl possibility connect to the weak signal AP and effect on the performance.
These are the details for reference:Client detail

- CCX version 4 supported

My internet is typically just fine but when I try to use LAN it cuts in and out every few minutes, which as you can imagine ruins everything. Currently using wi-fi as my Ethernet port somehow has ceased working. No other computer wired or wireless in my house has this problem.

I'm trying to portforward for a game, and in order to do so, I'm setting up a static IP. I've portforwarded in the past and all's been fine, but when I'm trying to set a static IP now it allows me to portforward and host the game, but whenever I try to log into any sort of website, it cannot find the page. The only fix to this is to allow it to obtain the IP address automatically. I've had a static IP in the past and yet I've never run into this issue before.
When I go to my TCP/IPV4 settings under the properties of my selected internet connection, I open up my ipconfig(I'll post it below) and select "Use the Following Ip Address". I then input 192.168.1.73, to change it to that.
Then, I click on the subnet mask box and it auto-fills 255.255.255.0, which is listed under ipconfig anyways, and for default gateway I input 192.168.1.1. I leave the DNS server boxes blank because it doesn't list them under ipconfig and it's what I did in the past to achieve the same results. After I click OK, the issue I listed above begins.

Windows IP Configuration
Host Name . . . . . . . . . . . . : Tim-PC

Windows 7 32 bit laptop ----> Windows 7 64 bit PC with USB network adapter.
I'm trying to move a folder from one computer to the other. There are about 300 files totalling 3mb.
At around "234 files remaining", the transfer freezes, and after a minute or so, the network connection on the destination computer is shown as Disabled. If I right click and choose "Enable", it makes the attempt, says "connection failed", and then "It is not possible to connect at this time. No network was detected. You may need to plug in your network cable to complete the connection."
What will fix it is unplugging the USB network adapter and replugging. But it only allows a little bit more transfer before it happens again.
I tried initiating the transfer from one computer, and again from the destination (bringing the files to it), but the problem occurs just the same. On additional attempts it will reconnect to the other computer and allow me to browse the files, but the connection crashes again without any more progress. My internet connection is fine otherwise, doesn't do this unless I'm transferring data across the network. I disabled Eset real-time protection but have windows firewall up (I'd rather not turn it off).

I have an ASA 5505 running 8.2
I used the ASDM wizard (6.3) to set up a remote VPN. After slightly adjusting the wizards configuration the VPN is working well.
Now I need to change the Outside interfaces IP address. When I do that the VPN no longer works. If I change it back to the original value the VPN works again.
What configuration changes do I have to make regaurding the remote VPN after changing the outside interfaces IP address?

I have upgrade the firmware on several RV082 (and RV042) model routers, and all of them have had subsequent WAN connectivity loss. The WAN works for a while, then stops working until the router is restarted, then fails shortly thereafter. I would assume it was some configuration corruption on incompatibility with the upgrade, but the symptom has been universal. EVERY 2.x upgrade I've made to a RV082 or RV042 router has exhibited this symptom. Reverting to the 1.3.98-tm firmware fixes the issue.

So (foolishly) I let the software updater delete Java 6 (which only Apple provides), and I installed Java 7 from java.com. Was running ASDM 6.4.9, all I got was the Java 7 splash box. Updated ASDM to 6.4.9-103, same problem.
I can run ASDM in one of my VM's, but it's a pain.

I can successfully make and receive VoIP calls via a Cisco SPA 303 IP phone, my iPhone 4S and a sogtphone on my MacBook PRO, using both DrayTEL and Sipgate as ITSPs. The Cisco phone is one of seven connected through the 3CX PBX software; but the iPhonne and the MacBook bypass the PBX and connect directly to the ITSP via the TP-Link router and the staellite modem.However, when I try to make or recive a second (simultaneous) call, both calls start breaking up.This happens both with the Cisco phones and with the iPhone and MacBook; so it's not a problem with the Cisco phone or with the 3CX soft PBX, since neither of these is involved when using the iPhone and the MacBook.I have tried various port forwarding configurations over the last few weeks, but still the problem persists. The current forwarding arrangement is ports 5060-5080 and 5090 and 9000-9049 for the PC running the 3CX software, and ports 5160-5180 for the MacBook. The iPhone has sipgate.co.uk set as both the Local and the External PBX IP, and the PBX port is 5060. The Local SIP port is 5964 and the Fisrt RTP port is 4000.

After some time of usage (typically days), I notice that Bonjour networking degrades. That is, the various Apple computers on my network can no longer see each other via Apple's Bonjour protocol. They can still connect directly using IP addresses however. The only solution seems to be a reset of the router. Are there some detailed logs I can look into to determine what the problem may be? The logs shown in the web interface don't seem detailed enough.

Currently, I have a Cisco 4948 in office that connects to a remote site via BGP. From what I am seeing, when connecting a new device to this switchport (we connect devices to this switch for a multicast VLAN that is set up), the BGP link fails after roughly 20-30 seconds. The switchport is not tagged with a VLAN, or any other config. Just a plain old port. This outage continues until the port is added to the mutlicast VLAN.
