My desktop and all 3 iPhone in my house experience this problem. The internet connection slowdown to 0-100kbps for about 3-6min and probably 5-10 times in a day.
It usually happen at night time, probably during time of many neighbors are using internet.
All of the iPhone, including one just bought last month face this issue, but no problems with iPad, android phone and smartTV.
I have tried many methods including upgrading router's firmware, reinstalling network card driver. This problem even occur right after i restart my router. I also change my router channel from time to time to a less crowded channel but little help.
Shouldn't be my network card problem since this happen on new iphone as well but i just ordered a new wifi adapter to try this solution anyway.
