@doonboy can you log into the modem, navigate to the STATUS .... DOCSIS WAN tab, copy the signal level table, from the first Downstream line all the way to the bottom of the OFDM upstream data and paste that into a post. Ignore the upper modem specific data table. The copy and paste process will paste in the text contents of the table. Lets start with that and see if any problem is blatantly evident.
Personal opinion, that indicates that there is some issue with the OFDM (Orthogonal Frequency-Division Multiplexing) channel between the CMTS and the modem. The use of OFDM should result in better performance, however, a lot can happen over the span of 192 Mhz. As modem users, we don't have the tools available to judge the performance of the OFDM channel, beyond a simple speed test. In cases such as yours, where something is obviously going wrong, the end user is hooped and completely reliant on the techs to solve the problem. I've already pointed out to @RogersSergio that OFDM performance such as what you experienced is an issue for a good number of customers. No OFDM, no problem. That pretty well sums it up. Rogers is going to have to improve its oversight of the OFDM channels to detect problematic areas, and spend the necessary resources to correct the problems.
The black dot at the back of the modem signified that additional shielding had been installed over the cable's DOCSIS tuner. Two dots signified that the modem had been tested as well. Now, that's been a while back and I don't know if that policy is still in effect. I suspect that isn't the case anymore and that additional shielding is now part of the design and production. Rogers has recently received 20,000 of these modems, so, in theory, they should all have additional shielding installed.
Without that shielding, the wifi's 2.4 Ghz network would cause EMI issues with the DOCSIS tuner, so the modem's performance as a whole would suffer.
In theory the white 4582 should have better basic wifi performance. The 2.4 and 5 Ghz antenna are all at the top of the modem instead of being mounted on the motherboard, where there was the possibility of interference from parts of the motherboard. Just to note, Beam Steering for 802.11ac wifi networks is not enabled on the modem, which is unfortunate. That might not make a huge difference, but is probably enough to move the wifi adapter down to the next, and faster level, in terms of the Modulation and Coding Index level that the adapter is running at. That index can be seen here: http://mcsindex.com/
As for the wifi issues, can you direct your sister's attention to the following post:
http://communityforums.rogers.com/t5/Internet/slow-wifi/m-p/399949#M47222
That post includes wifi settings for the modem which will hopefully alleviate some or all of the issues. I say some or all as each home is unique in terms of the wifi interference that it sees from its neighbour, so, part of this issue is to understand what you're dealing with in terms of clear channel competition. That's the second part of the post, to determine who your competing with and determine what you can do about it, if anything.
I'll have to update that post as Metageek, the makers of inSSIDer have come out with an inSSIDer Lite version. Hopefully that will make up for the fact that they appear to have abandoned the home wifi market. That lite version should display the local 802.11ac networks from her neighbours homes. The inSSIDer version in that post only properly displays the 802.11n networks and attempts to display the 802.11ac networks. The Lite version will hopefully do that properly. Only hitch appears to be a requirement to set up a freebie account with Metageek. This version has only been out for about a week, so, I don't know if there is any way around the freebie account setup.
I wouldn't count on Tech Support to necessarily look at the specific wifi settings. The feedback that I've had from other customers in the same situation is that changing the wifi settings as suggested in that post has made a difference, so, I'd check those first and adjust them as necessary and then check out the wifi environment to see who she's competing with. Changing the 5 Ghz channel to 149 or above and setting the bandwidth to 80 Mhz should help. That channel change to 149 or above allows the modem and devices to use 1 watt for a max power output. Channels 36 to 48 are restricted to 50 or 200 milli-watts depending on when the device was approved by Industry Canada, and the middle Dynamic Frequency Selection channels 52 to 144 are restricted to 250 milli-watts. So, moving up to the top channels should result in better received power levels, better signal to noise ratios and better data rates. That is incumbent of course on the local competition from nearby modems and routers.
@Radar2000 to access the modem's user pages, bring up a web browser and enter 192.168.0.1 or 192.168.100.1 into the address bar to access the login page. The credentials are;
username: cusadmin
password: the modem's wifi password (unless your sister has logged into the modem and changed it to something else, which can be done to separate the wifi passphrase from the modem password. )
From there you can navigate to the Wireless .... Basic Settings tab. Check the settings for both 2.4 and 5 Ghz sub-tabs as suggested in the following post:
http://communityforums.rogers.com/t5/Internet/slow-wifi/m-p/399949#M47222
When all of the changes have been made, reboot the modem ADMIN .... DEVICE RESET .... Reboot.
@nav2004 you can do exactly as you have outlined, which is to run the modem in Gateway mode with the RT-AC86U in Access Point mode.
To do that, connect one of the modem's LAN ports to the 86U's WAN port, as is normally done. Leave the modem running in Gateway mode. It will provide the DHCP services to the network, supplying all of the LAN IP addresses.
With a pc connected to one of the 86Us LAN ports, log into the router, which should be at 192.168.50.1 for the 86U. Set the router up as per your requirements and when that is complete, switch the router into Access Point mode. To do that navigate to the 86U's ADMINISTRATION .... OPERATION MODE tab. Select the Access Point mode and save the changes. When that is complete, log into the 86U again and run a reboot.
Depending on the distance between the modem and router, you might have to shut down the modem's wifi. If the two devices are separated by some distance, such as across the house, then its your choice to run both devices or just the 86U. Our 86U is located at the one end of the house and provides coverage to the back of the house, upstairs and downstairs as well, so, I have no requirement to run the modem's wifi.
The disadvantage here is that the 86U is far superior to modem in terms of its LAN capabilities, so, letting the modem run the network is less than ideal.
For the problem with the USB drive, consider formatting the drive in an Ext 2, 3, or 4 format. I'd start with the Ext 2 format, set the modem to run in Bridge mode with the 86U in full Router mode, as one would normally run the combination of a modem and router. See if the Ext 2 format resolves the file problem that you were experiencing previously. If that doesn't work, in terms of the file situation on the USB drive, move onto an Ext 3 and possibly Ext 4 format. I think that the final answer might be to run a NAS via ethernet instead of using a USB drive. That seems to be the common advice for problems when attempting to run a USB drive as a NAS device.
Here's a reference for format programs that support linux ext formats.

I would also ensure that the 86U is running up to date firmware. Asus has been rewriting the firmware for most of their routers, so perhaps there has been a change for the better in terms of the usb performance. The latest firmware version can be found here:
https://www.asus.com/us/Networking/RT-AC86U/HelpDesk_Download/
Download the Windows 10 64 Bit bit version (they're all the same end product) to a folder of your choice. Extract the contents and then run the update function located in ADMINISTRATION .... FIRMWARE UPGRADE .... Manual firmware update: Upload (function). If you happen to see a yellow flashing exclamation mark at the top of the user interface, that's an automated update function. Select that exclamation mark, which also serves as a link, to start the automated update function.
If you are updating from the older generation .380.xxxx firmware version, when the update is finished, log into the router and run a factory reset. After the reset, set the router up from scratch, don't use a backup settings file as that file will not be applicable to this firmware version, which is a .384.xxxx version.
If you still have problems with the usb function, signup for a freebie account at the smallnetbuilders.com site and post any questions you might have in the following Asus forum:
https://www.snbforums.com/forums/asuswrt-merlin.42/
Hopefully you will receive adequate responses to your questions.
Here's an interesting observation regarding IPV6 for a RT-AC68U running in Access Point mode. If this is an issue for the 68U, I would expect the same issue for the 86U:
https://www.snbforums.com/threads/ac68u-ap-mode-ipv6-not-working-over-wi-fi.47880/
To log into the modem, use 192.168.100.1 to access the login page. That address works for both Gateway and Bridge modes. The user credentials are:
Username: cusadmin
Password: Your wifi passphrase
To log into the modem thru the router, use the same address and credentials. You don't have to make any changes to the hardware connections.
Hope this helps 🙂
