You need to use your TWC modem's wireless rather than someone elses.
Wifi hotspots Speed and access time can be limited by the shop's owner, it may be on their modem as well.
If your work place requires you to have an internet connection, they should be providing it not stealing it from the business next door. All the above you mentioned is consumer connections in guest mode....
Next, many are set to only provide CUSTOMERS 1 hour of service in a 24 hour period. If more is required, they need a private business wireless account set up. and it will be cheaper with Google or Uverse.
A bit of clarification. This forum is Peer to Peer support. TWC does not provide direct support and in no way did TWC indicate you were a thief.
If you are having difficulty with the TWC WiFi Hotspot and have not been able to sort out the problem here or on your own we encourage you to phone our Wifi Support group at 888-851-9350 for assistance.
Thank you for participating in the Forums.
Have a good rest of the day!
