Laptop wireless connection?

If i get a router for my Laptop would i be able to use the internet if say my mum was on the internet on her PC at the same time and i want to use her connection?

I dont want to share files or anything like that just to use her internet connection so i dont have to pay for a seperate one.

Sorry first time i bothered to get a Laptop so any info would be a great help.

Thanks

Yup it would be really as simple as that!

Just get a nice wireless router (I personally have a 3com one) then make sure you set up WEP (Web encryption) to stop people stealing/leeching off your connection. It took me literally a few minutes to set mine up with my macbook and ds lite :)

As dark_shadow says, it is as easy as that. Although it depends on your Mum's internet connection method as to what you'll need.

[SIZE=2]I think WPA is better encryption than WEP though.[/SIZE]

Agreed.

However, I had huge problems with my DS Lite accepting WPA, so I just opted for the latter.

Assuming he's a newb, wep should be sufficient. At a later stage he can fiddle around and see if he can get it configured :)

What is the furthest you can use your laptop from the wireless router?

Also, does the internet speed get slower the further you are.

Thanks

No the signal will just weaken.

You should be ok for around 50mtrs depening on the amount of obsticles in the way.

I would say that 128bit WEP is better as WPA can be hacked in around 30 seconds if your in the 'know'
#6
According to some report (I have a link to it, but it is in Russian - can send link via PM if someone is interested), WEP-64 can be hacked in 3 secons, WEP-128 in 7 seconds. They also managed to crack WPA-PSK within 90 minutes (brute force + dictionaries).
#7
Yeah WPA is definitely more secure than WEP but both are easily cracked so it seems.
#8
Although WPA is more secure than WEP, 128bit WEP is normally the better option for a home setup if connecting older spec pc's/laptops plus gaming systems, as many will not support WPA.

All encryptions can be hacked eventually, however if you customise the name of the router, hide the SSID so that you are not openly broadcasting your signal, password your router and enable the firewall, you will make it harder for anyone to mess with.

Hi,

Another question,

Up to how many pc's/laptops can you use with one internet connection?

Thanks
#10
[SIZE=2]About 16 wirelessly and as many as you like connected via network cable.[/SIZE]
[SIZE=2][/SIZE]
[SIZE=2]Obviously this would share your internet connection over them all so would slow them down if all were surfing net together.[/SIZE]

It is normally 64 clients/channel AFAIR. As to "as many as you like via cable" - this is not entirely true. Not many home routers can support more than 255 clients (including WiFi ones). In reality, this number is even less, because some addresses are reserved for router itself (web interface, telnet, etc).
#12
Well he's hardly likely to have more than 255 clients on a home router.

As for 64 clients on wireless i'd love to see that. We've just put £1k Cisco AP's in which cope with 32 clients together. 64 and you would die of boredom.

spot on fella. :thumbsup:

Thanks friends, this is becoming very informative for me.

Now for the next question!

Let’s say if I am using a 4mb broadband and there are 4 internet users to the same connection, would the speed come down to 1 mb for each user?

Is it as simple as that?


Thanks
#15
No you would get whatever is left.

Say laptop 1 is using 20kbps bandwidth, the other 380kbps would be availble to all the others if needed. It is still only one internet connection. same as if you had 4 internet explorer windows open, it just spreads it across as you need it.
#16
No, because:
a) 4MB is maximum speed, in reality you might have way less.
b) It is highly unlikely that ALL users would want to do very intensive communication at the same time.

If you want to specify bandwidth limits per user, then you need to look at routers with QoS (Quality of Service) option.

It will be shared, so will vary depending on how much a user is uploading/downloading at the same time etc etc,

8mb is the max speed which is what I get and generally if i'm d/ling off a good site I get around 750kbps so I am getting the ull speed.

If your connected at 4mb, that is the speed you should get - unless the other 49 people on your network at the exchange are d/ling at there full bandwidth.
#19
It depends on exchange, number of active connections at the same time in your area, distance from your exchange, 'fair use policy' at provider's level, etc.
Take a look at typical ADSL contract - there is no warranty you'll ever get what you are paying for. They always state 'up to'.
#20
Distance from exchange is irreleavant. If your modem is connecting at 4mb then that is what you should be getting. Distance is only an issue when you first sign up as you do not know what your gonna get until its connected. I was told 4-6mb but get 8mb 24/7.

It wont suddenly just change to 2mb just because your 5km away from the exchange.

The only time your connection will 'slow' down is when there are loads of active users d/ling, i.e 6pm weekdays are usually the slowest with people logging on after work etc, and Thursdays as everyone in the UK sets Lost to download! lol.

We have a 2mb (boo hiss!) at the house split Wireless between 4 computers, It certainly isn't split equally. For example if one person was using BitTorrent or watching internet television on Winamp then they can steal almost all the bandwidth.

- Of course I've secretly made sure 2 of the computer illiterate housemates can't steal all the bandwidth and ruin my matches on BF2142 :)

The distance is important apparently. For example, my house was 8 miles off exchange and BT engineers only guaranteed 1Mb for my connection. So in this case, whatever contract I'd take, I might not get more than 1Mb. And there was no possibility to know this before I signed up for contract (it was TalkTalk - worst provider I ever had).

Thats what I said. this distance is only important when you actually take out the contract because you don't know what speed you will get. But once you get that speed, that is what it will stop at until the next time BT mess with the exchange!
#24
Yes, but the point was that even if your contract is 4Mb and modem is connecting at this speed there is still no guarantee you'll get it. Contention on exchange level could still be there (unless you very lucky), contention on provider's level also there (although there are few providers that promise no contention inside their network, like Zen), FUP (port throttling, traffic management) might be in place, etc.
#25
If your connecting at 4mb you will get 4mb probably aound 95% of the time. I do anyway, but my isp dont do port blocking or traffic shaping. It all depends on what you use it for. Unless your a heavy downloader you probably wouldn't notice if it slowed down.
#26
With TT my connection was anything but the speed my contract was for. Then I moved to Zen and it was much better (although much more expensive). Take a look on ADSLGuide, many people are not getting full speed out of their connections.

Anyway, this discussion is now way offtopic. We can start a new thread if you wish and continue there.
