How easy hacking WLAN is

So from now one, you'd better think twice before securing your WLAN with only WEP or even worse, nothing.
WPA2 is the safest way to go now, upgrading your hardware is worth the consideration if you plan to order your vacation via the internet ...

there are several things you can do to secure your wireless network without having to enable these speed-crippling encryption methods, WEP has a rather small speed impact, but WPA (not even talking about WPA2) reduces your 54Mbps (at best) to a miserable <11Mbps if you are lucky.

in return you get a slow connection to you local network, and the internet, there you have invested into the latest high speed broadband 20Mbps account and your LOCAL network is unable to cope with it. Great.

How about, on your wireless router, disable DHCP, configure the IP range something OUT of the ordinary (not 192.x.x... but 172.127.123.x for example). then set your clients up with a fix IP address; then enable MAC security filtering, then enable access to the internet ONLY from the few allowed IP addresses.

secure your PCs with strong username/passwords.

and when doing transactions on the web, use HTTPS and SSL.

and at the end of the day, I just put 300M UTP CAT 5.E cable in my house and disabled wireless on my router,

it's slow, buggy, not reliable, insecure and slow. I wasted €250 to find this all out :/

no wireless for me, until they can get 100+mbps securely and reliable in the air.

I have the same thoughts about wifi as JM

I'll never use it here

I live in an appartment for now that I rent, I have to use Wifi. I'm not allowed to drill holes in each wall

.

jmke · 26th October 2006, 20:28

I also live in a house I rent, I didn't drill any holes

wutske · 26th October 2006, 21:24

okay, 1+ for IP/MAC-filtering

and 1- for WPA(2)

.

I have a slightly different opinion about WiFi. For laptops/pda's/... wifi is good and usefull (like at school during the lesson, we can get on the internet --unsecured

-- whithout having the need for a cable and yet we can download at +1Mbs/s

), but for a desktop I'd still prefer to have a simple cable.

setup here:
1 wireless router downstairs and 1 upstairs. WEP enable + mac filtering + fixed ip address in a not default ip-range.
only allow internet from certain addresses.

enabled https for managing my routers.
Speed is up to 20 megabit and more (never tried to do more since I don't transfer large amount of data to my test laptop).

I can effectively saturate my internet connection with this.

I'm using 2 linksys wrt54g routers with custom firmware.

20 megabit = 2.5Mb/s ... too slow for me

WEP is insecure

Kougar · 8th November 2006, 21:41

Yeah, I saw WEP cracked infront of me in under 5 seconds. Was all the evidence I needed to change to WPA2.

Powerline Ethernet Adapter's are the new way to go! Also spent a good deal on expanding the range of my super-g wireless network,but simple switching to using the wall sockets fixed all the range issues, and it's worked great. The right kits will get you all the stable bandwidth ya need... now all they need to do is build laptops so when you plug them into the wall you're instantly connected to the network

I heartily disagree; getting 300-400kb/s over your local network is too damn slow to do anything useful with.

UTP Cat5e is still the way to go.
