This may have been discussed, but can't find a topic. So I upgraded to a Genie master with 2 Genie subs. Before upgrading, I had 2 laptops, and ipad, 2 phones, and another router connected to my OLD Verizon DSL Westell D90 modem. Running at 1.5 - 3 mbs speed (top speed offered to me). No issues with surfing the internet, nor speed of surfing. However, when the Genie was installed, and connected to the router (no issues connecting wirelessly), the PCs would be very slow and/or drop the internet connection... this occurred even if I wasn't using On Demand. If I used On Demand, the PCs would lose internet connection pretty much 100%. I would have to reset the router to get a connection, but the issue would reappear. Called Verizon - they basically think it's the old modem, so they are sending out a new one. We will see what will happen, but just curious if anyone else has had this issue. I just want to make sure it's not some type of configuration problem (like needing to use certain IP addresses for the Genies, etc.). Thanks.
