View 3 RepliesI opened a computer in other network via remote desktop(because I forwarded port in router)....and tried to access other computers in the network via remote desktop again from that computer but after I done, I don't know how to close the secondary remote desktop. There was one close button on the top, but if "close" it, whole rdp connection was closed. The secondary rdp connection is still open in the computer.

After a short while I have a connection and is able to access the internet. The connection wizard, however does not register that a connection has been established and continues to attempt to connect for two minutes, then shuts down and immediately starts for another two-minute try....and so on. If I shut it down it just pops up again.This has never occured before. I run Windows 7 on an HP with an AMD processor.

View 6 Replies View RelatedI've been trying to set up a customers security camera's for remote viewing. He has a HP running Vista, a netgear grt614 vs10 router, and a static IP address through Verizon. My problem is this. I set up port forwarding for port 80. All seems to work well sometimes and I can connect to his DVR no problem. Then other times I can't connect at all. I'll run a port checker and it will tell me port 80 is closed. Is it possible that Verizon will off and on block inbound port 80? I seem to only be able to connect during buisness hours. Is it possible that his PC needs to be on for the port to be open. The DVR is the server which is always on and the router is always on. I don't know why the computer would have to be on.

View 3 Replies View RelatedAbout a week ago my laptop started acting strange. I noticed when I brought my computer to my room (which is where i usually use my computer) it said that there were connections available where the signal bar is. Which is odd because it usually just auto connects. So i clicked on the signal bar and connected to my internet, but it lost the connection shortly after so I clicked connect again and it said windows was unable to connect to the router. Then shortly after that it said no connections were available. So i brought the computer to the computer to the family room ,where the router is, to check the router. It was nothing wrong with the router so I looked back at the computer and it was automatically connected to the internet with a five bar connection, but when i left the family room with the computer it immediately lost the signal. So i decided i should just stay in the family room. The next day the same problem occured and i went back to the family room to use the computer but i noticed the connection wasnt usually at five bars like it usually is wen im that close to the router but it was 4 bars or 3.
The next day i went over my fathers house for the weekend, and when im over there i pretty much always have a five bar connection even though im not in the same room as the router because im 1 floor directly above the router. Now when i used the computer over my dads house it had a 3 bar connection, disconnected from the internet at times, and when i try to connect bak it said that windows could not connect to router like it had said in my room bak at my own house, even though it always used to have a very high connection before this problem happened. So wen i got bak to my house i went to the family room to connect to the internet and now im having the same problems i had over my dads house. Now i try deleting some programs to see if they affected the internet and have even turned off some start off services on using mpconfig but that didnt work either
I just bought a Cisco Linksys E900 wireless router. Can someone explain to me why the router (192.168.1.1 on my case) has ports 1990/tcp and 5916/tcp open on the LAN?? I cannot find a way to close those ports.
[code]...
Every client on the LAN (wired and wireless) can connect to those ports on the router. I do not want that to happen. It is unncessary and it is just not secure. I only want the router to have port 443 open on the LAN for the web mgmt interface. I do not want any other unncessary port open.
I am having a problem with my router disconnecting every time that I close a browser window. I am pretty sure that it is a problem with either my Desktop or my WiFi usb card that is connected to my Desktop. I have tested this on my laptop and it doesn't seem to have the same issue. Has any heard of this or does any have a solution to how I can get this working correctly?
View 3 Replies View RelatedI boot up my computer. I close it over. come back later. open it. Computer will connect but with the small yellow triangle. Thing is though, it's only my computer that ever has issues with my internet connection. My sisters laptop has never had an issue with out internet. Yet my laptop is able to connect to the neighbors internet fine. The solution to my problem almost all of the time is to simply reboot my computer, which solves the problem(most of the time). But i'm getting so sick of having to do it. The other times when a reboot doesn't work I have to manually reset the internet. As i'm typing this I'm on my neighbors internet. my sister is connected fine to our internet but my laptop simply won't work with it so i'll have to reset it when i'm finished this Some useful information might be that this problem only started happening ever since my computer got wiped.I've tried updating the drivers but apparently they're up to date.

I have a WAP4410N which I have had for awhile and the performance was flawless at what appeaared to be 300 Mbps. I udated the firmware recently to 2.0.4.2. This is when the problems started. Within 15 feet of the acccess point it would drop the connection and speeds were under 65 Mbps. I factory defaulted the unit and reinstalled the firmware with no changes. I run several other access points of differnt manufacturers and I get fantastic performance on draft N and G. I did check all the laptops for network adapter incosistansies. Have I made a configuation mistake? I only changed the IP address to bring it into the range of other devices. I use a sa520 router and a Trendnet Gigabit switch and a server with MS SBS 2008 which works well with all but the WAP4410N.

The main servers are in a datacenter located in downtown.Each branch has a RV042 router with firmware version 1.3.12.19-tm (Feb 13 2009 13:03:21) installed.All users in this network have a proxy configuration pointing to proxy.[blah].com.br port 3128.the HTTP/HTTPS traffic should go through proxy only. [code] Some "smart" users were caught using Ultrasurf application, which changes the proxy settings to go through port 9666 or even 443.In other machines, we've found some black proxies [for example: 212.46.27.142 port 8080].
My objective:
- To close all ports in Firewall -> Access Rules section and grant permission only to some selected and specified ports.
- To redirect all HTTP/HTTPS connections to go to proxy's IP address only.
Which Access Rules can I set in these RV042s in order to block and prevent these users to continue abusing this network?The users who were caught using Ultrasurf were fired.
Obviously you do not want your cat6 lines running too close to your power lines especially when in parallel. The question though is how close can it be without causing interference?In my situation the wall I want to connect my main router to has a power outlet in the middle of it which honestly is where I would have preferred my network ports. Will I be OK if I run my cat6 in the wall channel directly next to the channel that contains the power line? It would be a standard U.S. interior wall residential power line. I should be able to get from 12 to 24 inches of distance between my cat6 and power line while still keeping my network outlet in a semi-central location.

We've had a lot of failures in the past due to multiple reasons, electrical noise, surge, etc so we decided to change to Cat.6 SFTP. The problem is that now , even with proper termination of the shielding at either one or both ends, the noise is so bad that packet loss is above 90%.

I have 2 laptops and 1 desktop in my household.Lately, I have noticed that webpages take way too long to load. Speedtest reported 2Mbps download and 0.07Mbps upload (that upload speed is not good, is it?)So on my main desktop I looked at the Send/Receive of the packets right after start-up and it showed like 200,000 sent and 7,000,000+ received. that is not normal, right?On my netbook, I looked at the packets and it showed 200,000 sent and 23,000,000+ received. I am thinking there is definitely something wrong with one or both of them.This laptop I am on right now is the only one not suffering from connectivity problems. Without the other two computers connected to the network, my web-surfing is completely normalAnyway, I dont know what the problem is, but I can't do anything on the internet. I can barely open a page on Google with those 2 computers. It's terrible. I have run Virus Scans and Malwarebytes + SUPERantimalware scans and ALL have come back negative. So...[CODE]

It takes 5 minutes to buffer a 3 min video, and if I want to watch a show, it take like 2 or 3 hours to fully buffer. My internet still goes fast, and I have trendmicro antivirus, as well as ccleaner, i updated my drivers, i have ie9 and adobe flashhplayer 11.1, i updated everything in windows update, i unplugged the modem for awhile and shut down more often, and opened it up and blew all the dust out. I don't know what else to do. I do have a cisco E2000 wireless router if that's a problem, and both my ps3 and my computer are on the connection, but my computer was working fine with both on the same connection for a year. I go on the http:192.168.1.1 cisco place, and i renewed ip settings, and nothing worked.
View 19 Replies View RelatedI've recently lost my ability to access the internet at uni and as this is quite an inconvenience I am considering some alternatives, the most viable one I've managed to come up with hinges on the fact that I live in a building which is only a road and another building away from the main uni buildings (3 buildings on 2 city blocks), basically it looks like this: UNI BUILDING 1 | UNI BUILDING 2 |ROAD| UNI BUILDING 3 |ROAD| MY APARTMENT.So I'm thinking of building one of these: url.. or waiting for the r20000g (dual band) to come out and buying that.THEN the area I'm having a bit of trouble with: I need to get reception about 600-700m away through buildings, so I've been looking at Yagi antennas and such but can't seem to find any information on the following:
1. Will a high powered directional antenna go through a few buildings and still make it 1km (.6 miles)
2. How directional is a directional antenna? like if I point one in the general direction of the building how accurate do I have to be? (I have no problem buying 4-5 antennas if I need to)
3. Do I need a new Wi-Fi antenna for my laptops? it seems odd to me that a laptop would be able to transmit back 1km while I need a giant antenna to get to the laptop (I know its not this simple but it still seems odd)
I have no problems with my adapter its just that my router is too far from my desktop and I need something that can reach far lengths , I don't recall what my wireless name is other than it uses 802 g type but it doesn't cut it when I want to play league of legends, so any recommendations? Also just moving my desktop is not an option
