How to set bandwidth cap on qt wallets?

[CryptoMine.ml]

I know this is a bit off topic. I have two PCs, one running Ubuntu and one running windows 7. On it has 12 or more qt wallets. I all so have a bandwidth cap of 15GB form ISP, the wallets use a lot of bandwidth. I would like to limit its IP to 5GB or sum thing. I can limit the IPs speed but I would like to set a bandwidth cap on the IPs. Can you that with openwork or dowry, etc? My router: TP-Link TD-W8970

You are using Bitcoin-QT? You do realize that that is an outdated wallet? I highly recommend upgrading to Bitcoin Core 0.12.1. Additionally, you should provide us with more information. If we assume that the wallets only spend download bandwidth (they need to synchronize with the network), we are looking at a maximum of (only for blocks):
4 320 MB of download per month (assuming 6 blocks hourly, multiplied by 24 and 30) - This number can way due to the total amount of blocks found in that time period + the amount of space that each block takes (this is why I've used 'a maximum of').
Are you constantly running these wallets, or do you just open them occasionally when in use?
Updated a clarification.

No I have Bitcoin Core and other qt wallets. I run them constantly. My download speed 10 Mbps and Upload 2 Mbps.

No I have Bitcoin Core and other qt wallets.

Which version of the software do you have?

I run them constantly. My download speed 10 Mbps and Upload 2 Mbps.

Go into Debug window (Network traffic), is the received or the sent data higher? Some statistics could help out when it comes to figuring out the best solution for your problem. Are you running a node by any chance (since it is unusual to leave a wallet open constantly otherwise)?

i think you can use an external app to do that. let me check it out.
