Satellite L500: WLan drops out and doesnt work most of the time

Question

hi everyone, i have a toshiba satellite L500 running windows 7. have been using iprimus internet, wirelessly, no problems for a few weeks,before that, was using it via ethernet cable as i didnth ave a wireless modem. my laptop was off charge the other night and went flat, next morning when i woke up and turned it on, it wouldnrt connect to the internet.. after hours and hours of phone calls to iprimus, and numerous winsock resets, ethernet cable testing, and modem resetting, they tell me that the problem is within my laptop...
So i rang toshiba.. and they got me to go into device managers, and then network adapters, and disable, actually uninstall the wireless drivers, then reinstall.. and it worked.. finally... (forgot to add with all the iprimus confusion someone had reset my passowrd and i had to configure that to the laptop..
so anyway, after all these calls, i did a complete restore of the laptop, and wiped everything and reinstalled it all, and therefore reinstalled the modem. this time in modem setup it was telling me the wireless network adapter was unplugged, and would only let me set it up via ethernet..
now earlier today i did have the internet.. but it dropped out randomly.. webpages will go slow, sometimes it will reconnect, other times it wont. now i thougbht i might try and uninstall and reinstall the modem again,s ame error, and this time, cant get on wirelessly at all.
ive googled to see if others ahve had this problem.. and seeing what other people wrote, i went into my battery settings, and checked the WLAN didnt go into sleep mode etc, and ive also checked everythings enabled. ive no idea what to do,, neither iprimus or Toshiba will give me any anwers, both companies are just blaming each other lol
so i
it does appear to be my laptop, as all lights are on modem.. and iprimus keep telling me its not registering with them ( the disconnections) so it must be my wireless. though everytime my laptop dropped out of internet, so would my bfs iphone we were testing, and so did my other laptop which is partially stuffed but could normally still connect to the net.. so thats telling me its a modem problem.. ive no idea what to do.. and cant keep this via ethernet on the bench in this new hosue ive moved into,as with 2 kids under 3, thats just asking for trouble..
anyone have any suggestion??
thanks in advance

Answer 1

wel after many more phone calls to iprimus, i finally found a helpful indian, who ran me through the modem setup AGAIN like everyone else has, this time in its security settings, he got me to change the wireless signal channel from 2 to 9, said that would improve the signal, every other person when explaining the issues i was having, always told me to set it on 2.. so this has improved it dramatically in the day, but at night, particulary around 830pm, it drops out over and over and over...
would this just be a faulty modem, and perhaps buying oen from a harvery norman etc would be better?? or could it just be iprimus as a whole with there wireless coverage? im not in an iprimus area, theyve borrowed the lines of telstra or something.. so im on a crappier plan in this new house, and dont have adsl2 just 1500 speed. would this have anythign to do with the poor reception, or perhaps is there something in my house interfearing, or in my neighbors house? there is a satelite here, but no actual foxtel connected, looks as though it has been before. there is also an alarm here, not in use though.. ive not even seen if it turns on..
