No Connections Available - What Settings In Administrative Tools / Services Should Be Enabled
Aug 23, 2012
My Dell laptop on my home network was connecting fine until I tried to figure out why it was booting and running so slowly and tinkered with the settings (per a web site with recommendations). Now it says no connections are available (there are, and other devices are fine). I tried all the simple solutions and have made any programs automatic that even vaguely look internet related and I still can't connect. The wireless adapter is enabled. I need to know what settings in the administrative tools/services should be enabled. The laptop is running Win 7 pro.

I have two servers behind the RV180 and a list of ports I would like to open to the public (80, 443, 21, 3389).In that case, I have to setup 8 Access Rules. I am OK in the first time setting up.But later on, if I would like to change the external IP <-> internal IP mapping, I have to change the Access Rules one by one for all related ports.
Does it has a setting for grouping the ports together so that I can set the Access Rules by one time only ?BTW, the summary view of the Access Rules in RV180 is not very clear, I can't differentiate the Rules for different Destination NATs ... I have to click into the details one by one ...

I have windows 7 PC. On the normal bases it has 3 internet connections 2 wireless and 1 hardwired. The 2 wireless are used for internet access and the hardwired is for my LAN through my router. The wireless connections are throught ATT mobile devices. I use my lan to share files through PC in my household and it has no internet access. The problem is that whenever I have all 3 of these connections connected windows always sees the hardwire connection as internet access so I can't use the internet even if my 2 other wireless connections are enabled. However, If I disable the Local area network connections and the leave 2 wireless connections enabled I have internet again.is there a way to just make windows use the hardwired connection as local and use the wireless connections for internet?

Ok, so I recently upgraded to a Linksys E3200. I am trying to get the QoS to work properly. I know that it is supposed to prioritize network traffic, so that if I have busy traffic but I am playing an online game, it should keep my gaming from stuttering while slowing other traffic down.
The problem is that every time I enable QoS everything slows down dramatically. I had a 200MB download that was going to take 5hrs with QoS enabled, that took 10min with QoS disabled. And with QoS enabled I can't even watch a youtube video without it pausing to buffer every 10 seconds. And that was the only PC/device using the network at the time. Again turning off the QoS WMM option solved the problem. I have noticed this problem with multiple routers and brands and usually just disable QoS as soon as I set up a router, however I heard that I won't get the full benefit of 300Mbps without QoS enabled.
I don't have any special Voice over IP needs, or video streaming etc. and I rarely am using multiple network devices at the same time. Is there really any reason I should enable QoS? Also I never really play with the settings for QoS, I just figure that since it comes enabled by default it should work for the average consumer.

I have a customer that is seeing output drops on a 2960S with mls qos not enabled. It appears that they are getting bursts traffic on the switch that is filling up the buffers, hence causing the drops. I have a couple of questions:
1. What are the default queue/buffer settings when mls qos is NOT enabled on the switch.
2. Is there any good documentation out there regarding the buffer sizes of the different switch models
The customer is looking for an answer as to whether or not replacing the 2960S with a higher model would eliminate the output drops WITHOUT having to mess with QOS/buffer/drop threshold settings on the switch, and Cisco doesn't seem to make the buffer sizes readily available for the the smaller Catalyst switches.

i have come across this solution to dual internet connections, c2950-i6k2l2q4-mz.121-22.EA14.bin is the IOS and the router is a 2950 Dual Wan model. I don't know alot about this stuff I'll admit, but it is on the default configuration with IP 192.168.27.7 255.255.255.0, gateway at 192.168.27.8. The hostname below is something I don't know exactly what it means but my guess is its the line at the command prompt with the name.
It has VLAN1 with fa0/1-24, gi0/1 - 2.
This is the script but I don't know why its not taking the commands as at ip sla monitor 1 I get invalid command error. What do the ! mean are they comments and not entered?

Configuration: VM with ACS 5.4 with patch 3. (upgraded from 5.2.0.26 patch 10)When I go on "System Administration" - "Administrators" - "Administrative Access Control" - "Authorization", I got this error:
What I tried:
"acs backup" on this server and shutdown
Install an ACS 5.4 with patch 3 on new VM --> I don't have the problem on GUI
"acs restore" to restore my configuration on new server --> I got this problem again...
I want to use this feature...After this error, others pages generate this error: I have to reload server or restart management service to get him back...How could I solve this? (I don't want to reconfigure manually the server )

We have a problem with CDP packets on sent by our Cisco 6509's. Unlike our other Cisco switches (4948G, 5020, etc.), the 6509 tags administrative traffic on the native vlan. As a result the CDP packets are sent with an 802.1Q header with a tag of 1. The other switches send the CDP packets untagged on the native vlan. This causes problems because we have non-Cisco devices in our lab that also receive and send CDP, but they do not process the packets that are tagged by the 6509. They see the packets from the 4948 and 5020 just fine.
How can I disable the administrative native vlan tagging on the 6509? Here is the current setup:
nwkdev-6509-1#show vlan dot1q tag native
dot1q native vlan tagging is disabled globally
nwkdev-6509-1#show interfaces gigabitEthernet 1/9/1 switchport
[Code].....

My Network Layout is as, Firewall (with Routing)------>Cisco 3560 Switch (L3)------> connected 8 Cisco 2960 switch (L2)----> all users I have configured 20 VLAN's on cisco 3560 switch with Dynamic Pool and Static, Means, 5 Vlan's are Dynamic and remaining are Static Our Company process provides only internet access to existing clients computers. Problem is that, I configured Static VLAN 5 for one of our Client in their seperate room, mean to say, i activated all ports of their room with Static VLAN 5. one day they configured own DHCP server on Windows 2003 Server with same subnet (Same as VLAN5) in their room without any information and now their all computer/ Laptop acquiring ip address Dynamically.
If i have configured Static vlan on that port's then how it is get Dynamic ip from same port's.How to restrict to permit another DHCP server/Service in our premises. I Do not want to give administrative control to Clients to do such kind of thing with LAN.

I was using my computer, and it was fine. Then my Mom used it, and when I got it back, the Internet didn't work. The network connections page looked completely different. It looked like it converted to ancient networking software. There's this American Family Insurance (my mother used to work there) connection that I didn't even know was there. They want me to use dialup for a broadband connection. All the stuff is just dial up and so old I don't remember seeing that stuff anytime recently. How do I change my network connections page so it can use wifi (what this comp has)?

I have been in this field for a few years and I found this book, Network Performance Toolkit: Using Open Source Testing Tools, to be very useful. It is full of great open source testing tools and has easy to use instructions for them all.However, to be more specific, I am looking for a packet generator that can simulate network packets over an extended amount of time. So the end result is I have this generator test my physical network for an hour but it simulates a week of real network traffic. Any tool, ideally it be open source?

I'm running Windows 7 Pro. I noticed tonight when I clicked on Network in Windows Explorer that in addition to my home PCs there is a PC with someone's name on it. My suspicion is that my wireless ISP has screwed up in some way. I ran SoftPerfect's Network Scanner and don't see any strange IP addresses, so this stranger's PC is not on my subnet. What tools are available to scan my network and give me more info about the stranger's PC?

Yesterday I had a installation of LMS4.2.2 who was working fine. I followed the procedure to install VMware Tools on the virtual appliance on this thread url...
Now I have a problem with the processes of LMS, but maybe it is not linked. I forget to do a snapshot before installing VMware Tools so I need to find a solution. A whole bunch of services do not start know. I tried to uninstall the VMware tools, to regenerate SSL certificate, I rebooted the server several times. It is running under VMware 5.1. [code]

After flashing the latest version of the firmware for the WRV200 (1.0.39) all of the pages on the web based admin tool are not working, and some are missing alltogether.I need to be able to re-flash the firmware to an earlier version (or attempt to re-flash this version) without using the web-based admin tool, as the page for doing the flash is one of the one's that is missing. Re-setting it doesn't work. I have tried searching here and through Google without any luck so far. The WRV200 works fine, but obviously is not locked down from a security standpoint, which is a large problem.
