I have quite often seen usage from midnight of last day till some time in next day reflect in the UI only by afternoon or evening. They may reset the usage and show zero, but the actual usage does get reflected later in the day. I think this is because they batch these update jobs in their systems to tackle with the load on the data bases. Also, their metering system does not always measure from 12 AM of 1st to 11.59 PM of last day of month. It may vary. Personally, I do not think there is any error in the metering system in this case.
If you have not used any data on that day at all, then its possible somebody else has knowledge of your WiFi credentials.
Also, don't forget that its quite easy to lose track of usage if you a WiFi setup and an always on connection. In addition to the possibility that your PC may be downloading system or app updates, its also possible that your iOS/Android devices can download app and system updates automatically in the background if they are connected to WiFi. Sometimes failed downloads can keep re-triggering the updates thus consuming data.
It just shows the currently connected devices ... That's all![DOUBLEPOST=1446468234][/DOUBLEPOST]I'm really considering switching to the Reliance Thunder 1099 plan ... At least, it doesn't have any limits, and most of the reviews on the internet stated that they get from 3-4 mbps speed constantly, as long as there are no cable cuts (occurred thrice or four times in a year on average). Anybody using this plan on TE?
Reliance doesn't provide any surge protection for any of their network equipment. For higher speed plans, they install a WAN cable directly into your house from some network switch they have nearby.
A high voltage reverse surge on their WAN cable fried my motherboard and CPU worth 36k. After that, I used the RJ45 surge protection on my Belkin Gold series power strip, but just a few days later another surge fried the surge protector.
Their service guy expressly told me that they don't secure their hardware from surges (as they don't take any liability for such hardware damage) and it is my responsibility to use a WiFi Router/Hub to isolate my expensive hardware. He tells me that way, every time a surge fries the router, I can buy a new one.
They were expecting me to buy a new router every time a power surge fries the router (Not to mention that this does not necessarily ensure isolation for other devices physically connected to the router).
That's when I decided to switch to a different ISP. I am not about to spend 1000 bucks every time they have a surge on their equipment. They tried to stop me when I applied for cancellation. I told them that if they compensated me for the hardware that got fried and also take responsibility to provide me with routers, I will stay on. That's when they shut up and processed my cancellation with much haste.
