I buy this modem after my Motorola Surfboard keep drop out . this one be more stable for the first few month , but after that I notice a sharp decline in my upload speed -lrb- it go from around 2mbp to .15 mbp -rrb- . after fight with my cable company for a few week and try just about everything I could think of to fix the problem , I finally decide to try switch it out with my old surfboard modem . this fix the issue . there be no doubt in my mind that this modem be the problem . I would not recommend this product and I be currently look for a new modem .
