Getting more than 10mbps via ethernet on NP topic

I bought a cheap straight-connector OTG cable from Amazon and when I hook up my USB ethernet adapter I only get 10mbps. The adapter is definitely a 10/100 adapter, but I am not sure if it is the OTG cable or the adapter causing the problems. I am inclined to believe it is the OTG cable since the ethernet drivers are pretty standard. If you have a OTG + ethernet adapter getting 100mbps, do you mind posting what you have? Currently my wirelss AC outperforms ethernet because of this handshake issue.
