Is cable modemor wireless modem faster??

Wireless seems to be more convinient horr, but is it true that other ppl may be able to tap into your connection?

And as a general qn, is transmission between cable faster,.. or without cable ??
Applies for mouse too

get wireless.. i dont think u will feel the speed between utp or wireless..

It depends on what sort of wireless you are talking about.

For LAN (not Net), between 802.11B, 802.11G and 802.11N, the differences are great enough.

Transfer rates of 802.11B is slower than 802.11G and 802.11N is way faster than 802.11G.

As for why the speeds of wireless don't apply to the Net, that's because the bandwidth is determine by your ISP.

As for hardware devices, there's no fast or slow, only responsive or no response at all. Wireless devices can go on and off, so don't count on them.

Wireless Speed:

802.11A - 2Mbps
802.11B - 11Mbps
802.11C - 54Mbps

This is when your endpoint is at optimal receiving range. If there's something interfering, you wont get your max connection speed.

LAN

Cat2 - 10Mbps
Cat5 - 100Mbps

And I believe now got Gigabit LAN (1000Mbps). I dont know what's the Cat for it nia.

As wires suffer from less interference compared to wireless, you will want it if you need uninterrupted connections.

Of course, you still need a fast broadband plan to get the most out of your router/ hub/ switch.

edit: mayi beat me in answering speed

Eh... whats 802.11C???

If you're transfering files over local network, use cable. Its faster and can reach up to 100Mbps.

Over the net, ur speed is restricted by ur ISP. Thats where your bottleneck is.

naturally it's called cat6

cable faster then wireless no doubt.

802.11N is faster than most Cat 5 cables. But Cat 6 cables will still win over wireless...

There is a GREAT difference !
if u try buffering videos... u'll see the diff.
esp if u internet connection is nt the fastest available...

cable is faster

No way. Unless ur internet connection is faster than 30Mbps ( max throughput for 802.11g ), there won't be a difference in buffering.

Starhub Maxonline is just SLOW, so don't compare that.

If the video is not on the Net.

Wah, that guy has his own flash streaming server?

Either that, he must be in dreamland.

Unless you keep transferring large files from 1 PC to another, 802.11g is more than good enough.

If you are worried about people tapping onto your wireless connection, use at least WPA and generate a key using this page. http://www.grc.com/passwords.htm

WPA2 is the best but if you have an older laptop, your wireless adapter may not support it.

I dont think U will find much of a difference with mouse...but for modem...cable is faster.this is wat I feel from my 802.11G and ethernet connections.

generally speaking,if a device requires a medium to work but is still slower than one that doesnt require a medium...pls throw that device away.

there is no 100% security....as long as U did encrypt ur wireless connection with at least WEP protocol...U are safe from normal innocent people looking for a wireless connection....if an expert is sniffing ur connection...then WPA2 might not even stop him/her...

I agree with you for the most part.

There's a big difference between WEP and WPA2 though. It's still a bit troublesome but you can capture packets and crack WEP relatively easily if you just put in a bit of effort.

For WPA2, it's probably easier to just kidnap you and torture the key out of you.

I do think WEP is good enough for most home users. Even if someone cracked your WEP key, that person probably just wants a free ride on your network. The person is probably not trying to steal data.

But almost all wireless routers and access points support at least WPA now. So why would you want to use WEP when you have WPA? It's like someone gives you a lousy $3 lock from the hardware store and an Abloy lock and you choose to use the cheap lock.

since U also agree that WEP is good enough for home use...we'll leave it as that for home...

for corporate...say...in a meeting....client wants to access internet with his PDA phone...office wireless network is encrypted with WPA2...but client's PDA can only support WEP...so...

therefore I think its a matter of knowing the hardware that might access the router(ur needs)...not the newer the protocol the better.

Yeah... it's always a compromise between security vs. convenience. And at the end of the day, the network must serve it's users or there's no point to the network.

If you have to offer wireless access and your clients don't support WPA, WEP is better than nothing. I used to recommend changing WEP keys regularly but there really isn't any point anymore.

But of course, security requirements are also important. In my office, if your device does not support at least WPA, that's just too bad.

Fortunately, even my old Dell Axim X30 supports WPA. I did recently deploy a wireless network where the client insisted on using WEP. I warned them about it but I guess they just don't take security seriously.

Some devices seriously need an upgrade - like PDAs.

We don't need another TJX here.

Corporate client??

Who are they? I'll demonstrate to them the weaknesses of WEP. =D

no, not corporate clients... he is referring to anonymous walk in clients that come and go... 64-bit WEP? 128-bit WEP? WPA-PSK? WPA2?

... these walk in clients... it is hard to tell what they support...

The best part is they are running something like a Point of Sales system over the network.

When I warned them that WEP is insecure, they said it doesn't matter. They said their even if someone cracks the WEP key, it's okay because all they send is a product code and a timestamp.

I told them it's still not safe. First of all, their protocol is unencrypted. There's also no authentication between the clients and the server. The server identifies the clients by the mac address.

Finally, the server runs on Windows and I don't know if they are using a firewall. I suspect not because the guy who was configuring it didn't even know what was a valid subnet mask.

But oh well... if they think it's not important who am I to argue. I just make sure they are isolated from the rest of the network.

Oh... if you have frequent guests who need to join your network and access your internal file servers (say auditors), it's probably worth it to set up 802.1x authentication with WPA and issue temporary usernames and passwords.

If you just have guests and you don't really care about security for them, do WEP and VLAN them off into an untrusted network. The WEP is there not so much for security but just to stop passer-bys from leeching off your connection.

EAP with WPA will require servers for authentication. If its a big enough network, I guess its worth it?

The cheaper way is as mentioned, leave the WEP guys on a seperate VLAN and route them to the network with extremely strict port restrictions.

Sometimes the problem is not with having uninvited guests on the network. Its having invited guests with insecure/infected/ laptops. Entire networks can kena for no reason.
