Thank you for the solutions. I'll try these out.
I've spent te last 3-ours going through these and everything matches your suggestions.
My system is a Dell Precision M3800 with Intel(R) Dual Band Wireless-AC 7260.
This finds and connects with networks fine. On my home configuration a Netgear N460 modem, it connects and maintains very good speeds. I regulary work out of a Home office that as an XFINITY cable modem. My system finds and maintains the wifi connection perfectly. The XFINITY modem is 10ft away, however, after the first 2-3 minutes the performance degrades to the point it is unusable.
Sitting in exactly the same position, with the wifi card in the Dell turned off. If I connect to the XFINITY via my SAMSUNG S4 Wifi, and then tether the laptop via USB, the laptop will run fine with no network problems all day.
As I said, the problems don't occur elsewhere with the Dell elsewere, they don't occur with the iPhone-5, HP Laptop, iPad on the same XFINITY modem, just the Dell.
Driver installed is Intel 4/16/2014 188.8.131.52, and Intel Proset 17.1.15
You have mentioned that it connects fine with other networks, correct? If so, do you experience the same kind of issue? Please consider calling you ISP (Comcast) to check the configuration of the modem. It could be that this issue may be caused by the way it is set .Check with them if they have any updates for this modem.
Yes it works fine with other networks aleki_intel
There are five other wifi devices that work fine in the same room as the Intel dualband wifi, including the wifi in the Samsung S4 which we use for connectivity via USB tethering as the Intel wifi doesnt work. When we called Xfinity they said since 5 devices work and one doesnt the only thing they could suggest was rebooting the modem which predictably didnt work. thats why i came here for help.
We would be more than glad to help you but if the adapter works fine with other networks and only with this particular modem it does not. It doesn't seem to be an issue with it since you went over the steps previously mentioned on post #1 and #3 and all matches. We wish we could help you with this modem configuration but since it is not an Intel(R) product we can not offer you proper support, that is the reason we kindly asked you to contact Comcast as they own the product. It seems to be a configuration issue. On our best effort to help you, we recommend that you contact our call center for live troubleshooting and review your adapter configurations to make sure all is order.
