Internet help.
I have Comcast. My personal modem is Motorola Surfboard SB6121. Router is Linksys WRT54GL.
This started last week when everyday at night, around 10, 11pm, or midnight, my internet would slow down to a halt, like all my bandwith is being sucked up, and no, I am not downloading anything at all. At first I thought maybe someone got onto my wireless network, but I see no one here. I thought maybe it has to do with Comast, so I let it go. But it's been a week, and it's still happening. My computer says I have strong signal strength. I called Comcast and they said I have strong signal strength. They suggest that maybe something is wrong with my modem or router. But can that be true? This happens only at night.
And for what is worth, I have tried powercycling, nothing worked. I even tried to just plugged the ethernet cord straight to my computer, and funnily my computer doesn't pick up any internet signal. But if I use my router again, I can use internet (like what I am doing now). I ran a speedtest and it says my download speed is 1.77 mbps, and upload speed .25 mbps. I don't know what that means. All I know is my internet is slow
And I just ran the speedtest again I am down to 2.36 mbps for download and .12 mbps for upload.
Any advice and suggestion on what I can do is appreciated.
