View 5 Replies View RelatedOur house has a cat5 line that runs from downstairs, around the outside of the house to an upstairs office. We are consolidating all the outlets that are randomly spread around the walls. The cat5 cable is about 6 inches too short to reach the new box so we figured we might as well run a new cat6 line. (I think we can make the run 20 feet shorter so that's a bonus.)The cat5 line has 2 jacks wired in series at either end. Everything I've read says cat6 is much more touchy and you should only expose the minimal amount of wire from the sheathing and don't untwist the pairs more than necessary. Can I put two jacks on each end of the cat6?

I test every room for continuity with a LAN tester and everything showed up OK. I then plug my Ethernet in one of the keystone jack and check for internet in every room with my laptop received no connection. I connect the same cable to my laptop and everything works fine
View 18 Replies View RelatedI am trying to wire cat 5 jacks into my walls and none of the jacks work. I have tried with multiple jacks and experimented with different wiring configurations but they still don't work. I know the wire I am working with is good because it had a male connector on it and I connected it to my laptop before I started wiring the jack and it worked.
View 3 Replies View Relatedthe internet is so poor I usually lose the signal, since it has to go through walls and a bunch of trees. My question is can I use the phone jacks in the wall to set up a second router or something to increase it. Or what is the best way to increase the power and strength. What do I need and how do I do it. My fathers router is under verizon vios. I plan on getting and xbox 360 with live capability and need good internet for that
View 2 Replies View RelatedWiring my house for Cat6 very soon. I already have most of the architecture decided on (except the decision of whether or not to use a patch panel, but that's another story). However, the office layout is giving me problems.
See, I plan to rent out my house some years down the road, as work will inevitably force me to relocate sooner or later. I know that *I* would want the ethernet ports on the North side of the office, but I can conceivably see somebody else needing them on the South side of the office. Cords running across the room are a pet peeve of mine, so that's out.
Instead of placing the jacks on just one side of the room, I'd prefer to put a jack on BOTH sides of the room, for each line. Like how you used to find two RJ11 phone jacks on the same landline. (note: only one pair of jacks would be used at a time). Is this easily possible with Cat6?
Does anyone Know if I can use Siemens cat6 jacks with any other face plate? I can get all Siemens stuff from work, but am not overly fond of how their face plates look to put them all over my house.
View 1 Replies View RelatedIs there an easier way to connect an RJ45 connector to a Cat5 cable, rather than the traditional method of lining up the wires by hand, inserting them in the right order into the jack, and then crimping it? It just seems like it would be very tedious if you had to do this A LOT, and I've had a good bit of practice. I saw that they make "EZ RJ45" jacks.. but do they make anything else that can make it easier? I'm asking out of curiosity, and not necessity. I have no problem wiring them, but it's just something that I hate to do (I think a lot of people would agree that it's not the most fun thing to do in the world of networking).

View 6 Replies View RelatedWe have a leased line from one office to a DR site which we use to back up our data. We are using Cisco 7204 and and OC3 circuit. The data is sent in blocks (SRDF) and we are sending changes only. However, we are getting requests from compliance to further secure this connection since it is a leased line. I guess I need to know how secure SRDF traffic is and then if required, how to secure it.

I have an ASA firewall and I have never configured an FTP server for a large scale network (well large in my opinion). I want to ensure we have the highest level of security available for the FTP and to limit only the specific users designated by an ACL. Would SFTP be the best available option for security measures? Should I only use Passive FTP and what range of ports above 1023 should I open for only 1 or 2 FTP clients at a time? Also if I use Passive mode do I need to use protocol inspection for FTP?Also, Currently I'm unsure of what files need to be accessed on our network but should the SFTP Server always only be installed within the DMZ?

View 2 Replies View RelatedI have a VPN on my ASA 5510 between (A)192.168.255.0/24 and (B)172.20.2.0./24. The purpose of the tunnel is to send kerberos tickets from our domian controller on the A side, across to a server at B, and receive a respose. I want to lock down inbound traffic to the A network, but not sure of best method.
I initially tried using an ACL filtering on ports, but soon realised the incoming traffic uses a wide range of ports so this is not really possible.Seeing as the A side will always be initiating the conversation, I was wondering if I could use the 'established' option on the inbound ACL for the ASA at A side, so that it would block any flows that are not initiated by the A side.
I have run three computers on my wireless network for a few years now, and have an HP OfficeJet 6500 Wireless printer that has worked seamlessly on all computers. That is, until I secured my router. I had an open wireless connection that I changed to secure (WPA) a couple of weeks ago and have been unable to connect to my printer wirelessly to print. It will print if connected to USB. The first day I was able to enter in my WPA key just fine, but not since. It doesn't appear to be finding my connection. Oddly enough one of our computers (a laptop) is able to print to this printer so I am not sure. All computers are running Windows XP, I believe with SP3. I use a D-link wireless router. I have tried using the HP solutions to no avail and have checked in the documentation that came with the printer.As an aside, I now appear to also have another wireless connection which is a "computer-to-computer" connection, I believe an ad-hoc connection?

View 4 Replies View RelatedI'm wanting to setup a small LAN in my office between 3 PC's for internet, file and printer sharing.each of the PC's has it's own printer connected to it and the idea here is to allow each of the PC's to have access to all printers at any time.Two of the PC's are running WinXP and one is based on Windows 7 Professional.The internet being used in our office is a shared 3G USB dongle (which we currently have to keep moving from one PC to another as the need be), so I'd like that when one PC is connected, all PC's should have access to the internet from that PC. (I would not like to connect the 3G USB dongle into the router).

View 4 Replies View RelatedI'm involved in setting up a new office for a business that's just starting out. I have some computer experience but not a whole lot in networking and security. We just have 3 people that will be working in the office and we need a way to store/backup/share files on the network as well as a way to access them remotely if need be. Our internet service is going to be providing us with a static IP. I was thinking that we could use an NAS with RAID 1 attached to the router, which is in turn connected to the cable modem, but I'm not sure if this is secure. Do we need some type of hardware firewall in between the cable modem and the router to protect us from the outside?

View 1 Replies View RelatedMy father has a small office at home with a server, used to store some files and software he uses and provide a stable network for the house. The network looks something like this:
-Our wall socket line runs to a modem we have from our ISP
-The modem then is connected to our server computer
-Which is in turn connected to a switch
-...where the computers and a router are connected to
This was set up by some computer company. Now for the question: we have used the router connected to the switch to connect wirelessly to the server to receive emails on our mobile phones (email runs via the server too). Also, my father syncs his Outlook diary on his phone this way. Apparently this doesn't work when connected to the modem, I guess because that signal hasn't been processed by the server yet. Now we are unable to connect to the router, presumably because it is quite old and ready for a replacement.
The question is: Can I just replace it with some random router and expect it to work? Or do I need a more specific router/more specific settings in the router to make this work again?
I just took a position and never had to work with networks that much before. Our lan is very slow and trying to figure out why. We have verizon business class 3 t1 lines dedicated 4 M. When I do a speed test we get about 4.05 average and 4.23 down. We have 11 computers on the network connected to a Dell power connect 2716. We have Two network printers and that is it. We are having problems with it being very slow when connecting to a share on the server or using RDP.

I work for a small business of five computers. We have a wireless network for internet traffic, and a wired network for file sharing. The wireless network works great for using the internet, but we are having trouble with the wired network.The issue is being able to communicate with all of the computers on the wired network. The ability to speak with all of the computers on the network is hit or miss. Generally, computer A can speak with computer B, C, and D, but D can only speak with A.
