    Hi. Recently the cable on my power adapter broke and I replaced. I got a 90w one, and then I turned on my computer it said something like "Your system will run slower, and the battery will charge slower, unless you start using a 130w power adapter".

    The problem is, everythings fine, except that I cant connect to the internet, or to my home network at all. I looked in device manager and theres a bunch of exclamation points next to most of the network adaptors.

    Would i be right in assuming if I just bought a 130 w power adapter this problem would be solved? Or have I doen some sortve damage just by plugging in the 90 w one.

    Or is there some way I can get the 90 w one working?

    Switching to a lower wattage power adapter shouldn't cause your laptop to lose its connection ability.

    I have a Dell Precision M6400 WorkStation laptop that was temporarily using a 130 watt power adapter until the correct 240 watt power adapter arrived.

    It displayed a warning about the lower wattage power adapter during startup, but it didn't affect its usage in any way.

    ----------------------------------------------------------

    What's the brand name and model name and complete model number of your laptop?

    What version(XP, Vista, 7, 8) and bit version(32, 64) of Windows is it running?

    ----------------------------------------------------------

    Can you provide an image of or can you advise what the device names are in the Network Adapters heading?

    What's the "service tag" number and/or "express service code" number on it?

    ----------------------------------------------------------

    Its Realtek PCIe GBE Family Controller ethernet device appears to be okay.

    Its Intel Centrino Wireless-N 1030 wireless device appears to have an issue.

    Here is the most current driver (16.11.0) for the wireless device at the Intel site.

    Cannot recall exactly where - possibly CMOS or in the Network Adapter - but I do recall a selectable option on Dell 600, maybe 620 - that disabled the Network Adapter on battery power. That would be the case using a lower power rated adapter. If you find it, and make the change to the disabling option, you should be good to go.

    I'm not there, so I have no idea how to resolve the wireless device issue.

    TerryNet or etaf or one of the other networking experts in the "Networking" forum may be able to help you.

    Is the Realtek wired ethernet device working okay?
