Hi, my name is Curtis, first off thank you upfront for any help.
I have been trying to help a friend that has a Dell Inspiron 7548 Laptop. She has been having problems with her USB ports. This laptop does not have an ethernet connection. She uses a USB to Ethernet Controller that she has purchased from Dell to connect to the internet. She also has a wireless connection. Her low speeds from the ethernet controller is where we first started picking up symptoms that something was probably wrong. She is in a small office, they have 300/25 bandwidth there. I did speed tests on several other machines and they are all getting these approximate speeds. I tested the cable that is run to her station with my laptop and I get appropriate speeds. I also checked the speeds on my laptop using the ethernet controller she uses plugged into the cable that is provided at her work station and I get appropriate speeds. When the controller is plugged into her laptop via USB, she gets around 80/25 from the 2.0 port, she gets around 100/5 out of one of the 3.0 ports, and the other 3.0 port she has gets about the same down speed at 100, but the up bandwidth is around 25. Those speeds were taken and were slightly fluctuating over about a 2 hour span, but other problems existed once I began testing things. I saw that the ports would intermittently not work for a few seconds at a time, and sometimes I had to extract what was plugged in and plug it back in to get it to work. I also noted that she has a hub plugged in on one side with a printer and a wireless mouse plugged into it, sometimes when I plug something into another USB port, it would sometimes cut one of the ports off. I have tested the speeds coming from the controller while the hub is plugged in and when it is not, it is about the same.
These have been the issues. What I have done to try to resolve these things are:
I have updated the chipset on this machine.
I have flashed the BIOS.
I have had Dell techs run several of their diagnostic tools.
I have altered the duplex settings to go from Auto-Negotiation to Full Duplex, this seemed to work for a short while, but then reverted back to low speeds.
I had Dell replace the daughterboard.
Nothing has fixed it, any ideas guys?
