edd_t Posted February 23, 2006 Share Posted February 23, 2006 Any gurus in physical networking out there??? At the moment my network is running at gigabit. Cat5e to desktops, Cat6 to servers, and a fibre backbone between switches on all floors. My manager wants to implement complete wireless networking for the company, on 802.11g. We have about 15 servers and 250 clients! And so far hes sweet talked the directors and they think its a good idea too (god knows how he did that) Please someone tell me that im not the only person that thinks going wireless would be a waste of time & money! Anyone know of technical stuff i can present to show that it will be a waste aswell... Link to comment Share on other sites More sharing options...
400BHP Posted February 23, 2006 Share Posted February 23, 2006 I do this for a living, why would you want to replace a secure structured cabling network running 10/100 and Gigabit with 54mbs? 108 at a burst? Not forgetting that no wireless network is safe, even if you use WPA and turn off your SSID AND use MAC filtering! Don't bother unless you have lots of mobile users. the only real reason for using wireless is if you can't run cabling or if its convienient for a notebook.

edd_t Posted February 23, 2006 Author Share Posted February 23, 2006 i dont want to! i love my cabled network. its the stupid managers idea, and i want to show the directors that its a bad idea.... Link to comment Share on other sites More sharing options...
cashpoint Posted February 23, 2006 Share Posted February 23, 2006 Just tell him business will suffer as everything WILL run slower. Wireless is a convience thing not a good idea for servers at all. Link to comment Share on other sites More sharing options...
400BHP Posted February 23, 2006 Share Posted February 23, 2006 Just tell the directors that the manager's idea sucks and he'll be reducing the network's traffic handling capabilities by over 50%. Or let him deploy the wifi and then sit back smugly and say "told you so!" Link to comment Share on other sites More sharing options...
edd_t Posted February 23, 2006 Author Share Posted February 23, 2006 Or let him deploy the wifi and then sit back smugly and say "told you so!" you wouldnt believe the amount of times ive done that in the past year! im gonna have to dig up some hard evidence on performance and stuff to show them on paper...

cashpoint Posted February 23, 2006 Share Posted February 23, 2006 Company we work with recently had the same situation where a manager thought wireless would be a good idea. The IT guy proved it wasn't by bringing in a wireless router and transfering a 500mb file by Wireless and wired too one of the directors to show him the difference. Ok so a 500mb file isn't really that likely but it proved the point. Link to comment Share on other sites More sharing options...
Pete Posted February 23, 2006 Share Posted February 23, 2006 Don't do it! There's a time and a place for wireless...stick with your hardwired networks that you know work. Have they been able to give you a significant reason why to invest this much expenditure? Link to comment Share on other sites More sharing options...
edd_t Posted February 23, 2006 Author Share Posted February 23, 2006 IT guy proved it wasn't buy bringing in a wireless router and transfering a 500mb file by Wireless and wired too one of the directors to show him the difference.[/Quote] thats a good idea, I do have wireless points in a couple of places, i could slap a pci card into the directors machines and prove to them its crap. Have they been able to give you a significant reason why to invest this much expenditure? i havent seen what my manager has shown them to persuade them that its a good idea! i bet its a load of bollox though!

400BHP Posted February 23, 2006 Share Posted February 23, 2006 if you do transfer a file, you can use ctrl/alt/delete to bring up task manager and then click on networking and you can see a graph of the speed. Link to comment Share on other sites More sharing options...

Let me see if I got this right...youre planning on moving your Servers...everything from a wired network to a wireless network.... amazing.... If youre talking about wireless to the laptops for mobile users...then sure...802.11g is fine...keep to the standards. make sure the wireless is well protected, many things you can do to secure it...I can only speak about our solutions..PM me for details.

Looking forward to this piece of info.... nothing wrong with wireless...its brilliant if you understand what its for, who its for, how to secure it, how to deploy it properly... too many cowboys out there that get it all wrong.

Whitesupraboy2 Posted February 23, 2006 Share Posted February 23, 2006 hows this, our network has a wireless network access point and lets just say it brought the whole network to a stand still!!! all because of another wireless accesspoint was within range. It was a nightmare diagnosing problem as well Link to comment Share on other sites More sharing options...
edd_t Posted February 23, 2006 Author Share Posted February 23, 2006 Imi, i really dont want to go to total wireless. thats why i posted to get some good ideas to show the directors that its a totally crap idea! I think the network i have at the moment is great, on tests ive never seen it go over 30% capacity! and we had one of them system intrusion tests a few weeks ago and they couldnt break into my wireless over and 8 hour period, sorted Link to comment Share on other sites More sharing options...
hob Posted February 24, 2006 Share Posted February 24, 2006 wireless is ok for notebook surfing, oo i can surf in the bath/garden etc... however streaming of data other than via browser is a no-no, there is no reason to use wireless if you can do it wired, I would ask, if we went wireless what would it prove? you can move the server about 1/2 meter before the power cord pulls out Link to comment Share on other sites More sharing options...

imi Posted February 24, 2006 Share Posted February 24, 2006 wireless is ok for notebook surfing, oo i can surf in the bath/garden etc... however streaming of data other than via browser is a no-no, Thats not true either...we use it worldwide and all our users are advanced users....e-learnings, emails, VoDs, etc.....so this statement of yours is simply not true.. Yes going for a 100% wire free network is plain stupid considering that youre going from gigabit (probably switched) to shared WLAN.......surely they must have been a reason why you went gigabit in the first place. amazing how these people are in a job......

Whitesupraboy2 Posted February 24, 2006 Share Posted February 24, 2006 sounds like the person / company that installed the WLAN had no idea what they were doing.... wasnt the guys fault, basically company upstairs was setting up their wireless and set their wireless point to join another by accident. So it joined to ours so all their traffic kept trying to go through our network, bringing the wireless access point to a stand still and somehow bringing network grinding to a hault.

Ark Posted February 24, 2006 Share Posted February 24, 2006 That's precisely why we don't use wireless where I am - there's no risk of remotely accessing systems 'by accident' (read as: bringing down the network) when you have to physically plug it it. Oh yeah, and wireless gets its knickers in a twist with 300,000 concurrent users Link to comment Share on other sites More sharing options...
hob Posted February 24, 2006 Share Posted February 24, 2006 Thats not true either...we use it worldwide and all our users are advanced users....e-learnings, emails, VoDs, etc.....so this statement of yours is simply not true.. Well no matter what I do, I cannot stream media (4-10GB) in a home-office using wlan, it simply drops way too many packets (even with wep off) and even if you set a cache in the player to say 15mb out of a 700mb movie, if the framerate changes it just stops (during a high intensity battle scene for example), the transfer rate also fluctuates way more than wired and this is where computers are within about 5 meters of each other. Anyway I switched on the streaming pc/router/media pc to a network via power supply (using the circuitry of the house as a data cable) and get around 35-40Meg a second transfer which is about enough, since it doesn't vary that much, althou I need to up the media pc its around 800mhz, and can't process the iso's quick enough, but can manage divx etc. Link to comment Share on other sites More sharing options...
Ark Posted February 24, 2006 Share Posted February 24, 2006 That could be external interference of course - radio phones, car alarm fobs...all kinds of equipment works in a similar frequency range. Are you anywhere near a military base (or police station)? Even microwave ovens can interfere. Link to comment Share on other sites More sharing options...

Are you anywhere near a military base (or police station)? Even microwave ovens can interfere. nope, mobile phone signal----> zero (cant call anywhere in the house), no milatary or police, quite remote part in Surrey, with hardly any of the above, once I even d/c all of the appliances in the whole house and did a test file, still the same, most people experienced the same, so I gave up and I just use it for browsing, and I know its due to transfer rate, because even with networking via the power supply (slower than normal networking) it can occasionaly momantarly stop for a second (for like a second in maybe 10 films, so negligible), then regain cache) Link to comment Share on other sites More sharing options...
GazzaGSi Posted February 24, 2006 Share Posted February 24, 2006 Sorry to go off topic here but I thought I may as well put my question here as its to do with wirelss internet. I have a wirelsess network in my house. I am on 2.0mb bt broadband. With it being wireless will i download slower than if I was on a non wirless network? I am thinking of upgrading soon, will i need to upgrade my wireless modem to cope with it? Thanks Link to comment Share on other sites More sharing options...
