Network Help! ASAP

post #1 of 24
Thread Starter 
I am a manager at a small business. My network is slow as crap. Like I get 1.5Gbps on every computer. The wiring is old and was installed with the building. Should I just have the whole building rewired (expensive) or should I just get a really good wireless router and get some wireless access points to connect all of the computers too. I am talking a total of like 8 computers and maybe a nash drive. My friend says wireless is unreliable and will be slower, but I think it would be the easier option. Any ideas?

PS- Can I plug a 8 port switch into a wireless access point without losing anything?

Don't do the quick fix. You will regret it later. Also, you would need to buy adapters for all of the computers.

You can plug a wireless access point into a switch.

I agree with this, do not go wireless for a business. More security holes, possible slower, costs more money then you are thinking with upgrading PC's labor and all parts needed...plus more things to go wrong. Best bet in my opinion is to have it rewired.

Well, all the computers are in a 8 port switch right now. I was wondering if I could throw a wireless access point on the switch to provide direct internet without running through all the old building wires. If I can do that, then I can bypass a lot of the old switches and wiring. I can take a picture if you want to see how bad it is.

Any idea what wiring is in place? Wireless could be an option but that also depends on the layout and cost could still get up there. There are a number of factors to consider before committing one way or another. You have stated 8 computers, how many servers? How is your servers connected? How do all these computers communicate? What is the back end, do these terminate into a Switch, a Hub, a Router or a Firewall?

If everything terminates into a HUB that right there is more than likely your problem. If you decided to have all workstations go wireless you need to understand the ramifications of CSMA/CA and could need a proper site survey.

Alot of this can be remediated with a properly deployed wireless infrastructure.

Right now it goes like this....Crap Motorola Surfboard Cable Modem>Wireless Router B/G>8 Port Switch>Wires through the wall>8 port switch>then the computers and printers. I dont have a server or anything like that. I dont need the wireless to be secured to the teeth. My important stuff isnt on the network. I just figured I could get rid of a lot of the stuff. Let me take a picture. I also run high powered laser cutters by the wires and I am afraid that is messing it up as well.

OP I would suggest bringing in some professionals to help determine what you really need. I would recommend contacting World Wide Technologies http://www2.wwt.com/ they can help you determine your best approach and can also provide you with some consultants if need be.

I have worked with them for a few years now, both in their Federal department and Commercial departments.

I'll assume that your 1.5Gbps is a typo because that's not slow, nor is it possible on copper. I'll base my entire answer of assuming your getting 1.5Mbps transfer speeds across your network.

I agree, don't do the quick fix. Wireless has its uses, but in a small business environment such as yours, I would recommend against it. Even tho the wiring is old, it MIGHT be possible to just replace the ends of the cables (and/or slightly alter the path some of the cables take to avoid EMI) to save you some $$. While not an ideal solution (far from it, in fact), I would recommend that before I recommend going 100% wireless. Without actually seeing/handling your *ahem* cables, I can't guess at how much/little of an improvement you'd see with this, but at 1.5Mbps, something's not right. Has it always been like this?

If you can get someone to come in and perform an RF Analysis, that would tell you what to expect from wireless (what frequency/channel to use, how much interference is in the air, etc...) I don't think those tests are cheap, but they're pretty important to try and avoid some of the headaches of wireless. I recommend against wireless because of the expense of these tests, and the lack of a big Fortune 500 kind of budget for your IT department.

This is all guesswork because I'm not there, I can't see your setup (building layout), see the machines (what make/model, what OS, what make/model NIC), run some tests(use a cross over cable and hook two computers directly together and see what speeds they get. If it's still slow, the cabling isn't your problem), etc...

EDIT - I spent too much time composing my answer. After looking at your pics, get your cables away from the power supply! If that is not possible, you will need to run a shielded network cable. Shielded Twisted Pair, or Shielded Coax should work. Since I haven't had to do any shielded installs, I don't know which one would work better, but I'd opt for shielded twisted pair. Of course, that means a complete re-cabling of the building.
