Exclamation Wifi inconsistency

Hi, i have installed a router into a metal workshop business via adsl broadband. Router setup with username and password and wifi channel set.

After a day or so the laptop will show a red cross and wont find the network wirelessly.

Plugged into Ethernet is fine and no red lights show on router so its purly an issue with the wifi.

Now i have tried 3 different routers and all have the same issues.

And i have tried multiple channels on the wireless.

Im going to today try and put a external wifi card in the laptop to make sure that its not the inbuilt wifi playing up (however it works at home fine).

After this im asuming that it has to be something in the workshop that is interfering with the wifi signal e.g welding machines ???

Hi arsenalbates

Have you tried moving the laptop around the workshop or maybe beyond an outer wall ?, maybe you can pinpoint the interference.

Core i7 3770K, Gigabyte GA-Z77P-D3, Coolermaster Hyper 212 EVO, Crucial Ballistix Sport 8GB DDR3, ASUS GeForce GTX 650 Ti, Corsair Series CX750w, Intel 320 Series SSD, WD Caviar Black 1TB, Pioneer BDR-207DBK 12x Blu Ray/DVD, Black Night Case, Saitek & Razer, Windows 7 Pro SP1 x64, ZA Antivirus + Firewall

Went back to check on it and the wireless switch was off on the laptop

unless the wireless keeps turning itself off on the laptop it does not explain previous problems. Will keep a check on it and report back.

if you open the command prompt (start run CMD)
then inside the command prompt type

netsh wlan show networks mode=bssid you'll be able to see the wireless strengths of the various signals around you.

if you can still see neighbours networks, but not your own then it's likely a router problem.

you should also try tuning the wireless off and on again, or restarting the computer to see if it's a problem with that.

finally, when you say that there is the little red cross, click on that and open the network sharing centre, then click on the adapter settings. I had a similar problem a while back when the wireless network card would just disappear and no longer be visible to the computer.

You can also check the power settings so that the computer can't turn off the wireless card to save power.
