Cant Join Any Server -Internal Exeption io.netty.handler.timeout.ReadTimeOut Exeption (MUST READ)

When I join any server I join for and I just float thought the void and then get the error message - Internal Exeption io.netty.handler.timeout.ReadTimeOut Exeption, I get this every single time but I can join my server but after 5 mins I lag out and receive this message, A lot of people get this and yet I have not and other peoples ideas have not fixed it for me . But it seems that its something to do with the router but it started when I updated to 1.7. I can only put 1.7.9 but this is happening for all 1.7 updates).I Think that until the 1.8 update, the only way to play for now I have found out is that use another internet connection but I don't have another. I hope Mojang read this and solve it for everyone so the community is happy . I have tried the following -

• Restarting my router
• Reinstalling the launcher and minecraft
• Removed the servers and added them back.
• Got admins to fix the chunk errors that I see and dosnt work.
• Asked for help...

Like this thread and get Mojang to see this!
