Aircraft X scheduled for flight to ZZZ at gate X in LAX. The potable water service access panel was on monitor for broken latches. I was assigned to accomplish the monitor to re-tape after water servicing. FAA inspector who was present at the time asked me for a reference to perform the job. I pointed out the number on the monitor sign off work card.  I also tried many times to open it on my iPad tablet before starting the job but was not I successful because of the poor signal at the gate. Didn't have at hand the paper copy reference before starting to perform the re-taping of the access panel when the inspector questioned me about the reference. I called the crew chief office and asked for reference to be printed and sent to me to the gate X because the tablet was working and not reliable because of the poor signal. [Suggestions are to] make sure to have the required paper work or reference on hand before starting the task. Supervisors and crew chiefs have to make all necessary references available as we all have to help each other on to make the terminal operation smooth. The tablet given must be reliable and effective to perform ones task. Trying to make the flight on time can sometimes takes your attention. I could have driven to the office and print the required papers.
Maintenance Technician reported poor WiFi at LAX.
