I have read some other posts with similar issues but not sure any ideas will work since no posts I have seen have had any of the same components as I have.... Here is my deal.
I have a Toshiba satelite - upper middle of road version.
I have comcast internet
I am using a Lynksis Cable modem
I am using a Lynksis wireless G router
I bought both modem and router in Sep. of 09
When I fist hooked it all up (new House) I had no issues was pegging between 100 and 144 mbs
For some reason one day 2 weeks ago I had my connection and network dissapear(deleted I assume). Any way I reinstalled the CDs etc that came with my router and am now recieving 58mbs at best, usually sits down around the 5.5 /2 /1 mbs range, it will spike to 58 mbs and occasionally hang around 18 mbs, which can work for about 10 to 15 seconds to 1 hour before dropping, this will happen consistently, but will always end up dropping to the 5.5 /2 /1 range. I have performed every test (basic) I know of and what others have had me try. I should mention the laptop is only 1 year old, also at the old house had same exact set up, but decided to buy new router and modem for new house and left the old one, anyway had similar issue at the old house but never really looked into it. just figured that since at the old house the Desktop (no longer have) was upstairs along with the router and the laptop (only computer in new house) downstairs through a couple different walls, was the issue besides alway had wired desktop to resort to, no longer have that luxury. I can plug cables right into laptop and have blazing speeds all day long, so its not an internet issue, every test i run comes back good or passsed. My router is no more than 5 feet away from laptop, so its not a range issue. Can someone steer me in the right direction
