General Internet/Wireless Networking Questions

post #1 of 7
Thread Starter 
Hi everyone, this is my post in this section so pardon me if I am asking some old questions...but here they are:

Wireless Internet Questions:
1. I have a SMC router and also a SMC wireless AP. I would like to set it so other people cannot share my network with me (stealing my network). I don't want to put a encryption on my wireless network because i have heard that it slows down the wireless network speed. My question is, can I block all of the non-use IP addresses on my network and leave the current in-use IP address open?

2. Currently, my wireless network is 802.11B and I have been using this for about 3 years. I am happy with the speed. I am considering to upgrade to Wireless-G (is this the newest or is Wireless-N the newest?), however, I am not sure how much difference I will be able to feel with the new hardware. Can someone please provide me with some insight on this? Another hesitate for me to upgrade is that these technology develops so fast that if I spend $100 dollars on the new hardware today, few months later, newer and faster routers will come out...So, I am just not sure if the speed will be worth it and if the money will be well spent.

3. Like I said above, I have the SMC router and wireless AP, I am have never tried to play with these hardware before and tried to change the settings or whatever, however, I would like to set something up so I can remote access my home PC from elsewhere. Can someone show the ropes and explain how I can set this up?

General Internet Question
I saw a sticky on the top fastest Internet speed...How can I improve my internet speed?


BTW, I am using cablevision/OptimumOnline and there are 3 wireless client and 1 hardwire client.

Thanks in advance.

Best thing to do then if you don't want to do encryption (I've never noticed it slowing my net connection done) would be to filter the mac addresses that you want to permit access to your network. Mac addresses can be spoofed, I'd highly recommend using WPA encryption and mac address filtering. If the encryption slows you network speed down I doubt you'd see the difference.

Wireless B is supposedly 11 Mbps, but it's actual throughput is more like 4-6 Mbps. If your internet connection is supposed to be 4 Mbps or less, sticking with wireless B shouldn't be an issue. Encryption MAY be an issue, since you do lose a little bit in the decryption process.

If you transfer large files between computers on your internal network (like between a laptop and desktop), you will see a huge performance improvement by switching to G. It's 54 Mbps, with about 25 Mbps of actual throughput. More than enough for the fastest internet connection, with or without encryption turned on. Unless you need more internal bandwidth than 25 Mbps, I don't think it's worth the $ for the latest and greatest technology. You can get wireless G stuff extremely cheap. Just stay away from Linksys...

thanks for the tips guys. i do do file transfer internally at home, but i got tired of the slow transferring rate so i am just using USB plug in drives now for large files.

I guess I will start looking at my options.

Now, is there a reason why you said to stay away from Linksys? I am using their wireless card on one of my laptop and so far no problem. I am considering SMC, Linksys and Netgear. any other brand you guys would recommend? Thanks.

I know this is going to start another brand war, but oh well. In my experience with lots and lots of different routers (I am an IT consultant), I have found that Linksys was the most flaky. It seemed that they had issues with dropping connections, rebooting or needing to be rebooted, and poor range. I have had good luck with D-Link and Netgear products. I have not had issues with Linksys network adapters or switches, however, just their routers.

Yea, as far as wifi router hardware, we have had problems with linksys B and G routers at work, at home I use belkins 4 wired combo wireless b&g and it works quite well after firmware updates, easy GUI too.

I have a Linksys 54 GL, and it never drops. I know I may be the exception, but i'm really pleased with it.

My DLink pci card couldn't keep connection more than 5 minutes, and a cheap zonet USB adapter is serving wonderfully
