Locked

networking problem

By pchlp ·
I have a client that has 10 desktop computers and and 5 laptop. They are connected to a 24 port hub and a router that gives them access to the Internet. The office manager wants to plug in a wireless router to one of the wall rj45 plugs and use wireless card for some of the laptops.
My questions is, will it work? Should this situation have a 24 port router?

yes you can put fw5 wireless onto a router hub exchanging the need for physical connection for the convienience of wireless connection. Of course Each laptop would need the wireless nic card to complement the other side of the connection. be aware that with fw5 anybody within distance of the hotspot fw5 can tap into your network even if they are outside in their cars! You will need to take special precautions to lock down your network so open port passage is not present for these pirates.

Yes, it will work, though as the previous respondent pointed out, there will be security issues that you'll need to deal with. I think the risk is over-hyped for most companies, as most are not really decent targets to attack, but it is an issue that you should address. As for the 24-port hub, it's overkill in this situation, but harmless. As a plus, it does give the client some room for growth, and it does nothing to reduce performance.

Do a little research on wireless access, though. The wireless NICs have limited range, and can be badly affected by the building's construction. If you have a laptop, a wireless NIC, and an access point you can install, do a walk-thru and see for yourself what kind of signal you can expect in that environment. You can get a good feel for the kind of problems you're likely to encounter after the installation that way.

Previous answers good. With regard to WLAN, often the hacks for this involve stealing your Internet bandwidth a much as anything else. make sure on your WLAN gear you:
Disable SSID broadcast.
Enable WEP encryption at 128 bits if it's got it.
Disable WEP authentication (believe it or not, this makes the whole system LESS secure).
Change the shared WEP keys reasonably frequently (configured on the clients and AP).
Change the keys immediately if a lap-top is lost/stolen.

Best of luck
