There is a chance that there is now a misconfiguration between the new settings of your DSL router and the Netgear repeater. Generally speaking, the wireless settings of the repeater have to match/mirror the settings of the base router station. (master/slave setup). The DSL router is master/base and the Netgear is slave with Security Options set to Off. Also have to verify that your master and slave are on same IP (especially if using diff SSID as identifier) with the last octet of slave different from master. (Normally master would be 192.168.1.1 and slave set higher to 192.168.1.50 or the like.) If you recently noticed a firmware update to your DSL router, chance there is a mismatch between master/base and slave settings.
Try removing the repeater (Netgear) during initial troubleshooting. Unplug unit so it does not broadcast.
Since the connectivity of your all your wireless devices seems to now be worse from the firmware update, I would simply factory reset the DSL router and do a clean setup. This is easier if you can run an ethernet cable between router and laptop but can be done wirelessly. (will just be disconnected more often during setting up the router.) Look on the router for all your default passwords and PIN numbers for admin login before resetting (normally on sticker on bottom). Also make a note of your current SSID names and passwords to make setup easier. Sometimes it is better to use a new SSID after resetting a router to force any connected devices to now use the new settings rather than any settings it previously stored in its cache.
To Factory reset router, press Reset Button or use paperclip in reset hole for 10-15 sec or until lights flash. After resetting and rebooting, login to your router using the default credentials and change the SSID and password under Wireless Settings. Reboot router again and then use the new SSID to verify wireless connection. Go ahead and leave Mesh enabled if set by default, for now.
Regarding the Premiere, verify in your router's Wireless Settings that the 2.4ghz band is Enabled and the Radio is Enabled/Broadcasting. Set your Mode/Protocol to g/n or n. (I would try g/n first). Then set your wireless channel between 1-11, do not use Auto ( 1, 6, and 11 are preferred and you may have to experiment here). Then set Bandwidth or Channel Width to 20mhz. (by default, you may find set to 40, lower to 20).
Reboot router, restart your Roku Premiere and see if you can connect.
Post back with any updates or questions. Include your router model numbers (both DSL and Netgear) so we have better idea of equipment if you need more help. Screenshots of Wireless Settings always help as well.
Thank you. I've tried that, and several other permutations. No luck. Failing that, I just factory reset my Roku, and that didn't fix it either.
Here's a screenshot of the networks in question. The Roku will connect to the first SSID listed on Channel 7. It will not connect to the second network (bolded), Channel 6. As mentioned earlier, the Roku previously connected to that network just fine, without any changes made by me.
I have exactly the same problem with not finding the wireless network.... suddenly, out of a clear blue sky... and have tried every single thing you have suggested, the website has suggested. To NO avail. Nothing helps! I cannot believe I cannot talk to someone at ROKU to get some real help So far, this has all been worthless and a gigantic frustration and wasted of time. Your "HELP" does not "help." So, what's next? Go out and buy Apple TV?
Since you never stated your actual model # or firmware version: Settings/System/About
Note that the 4620 (Premiere) is dual-band but the 3920 (Premiere) is not (and there have been many reports of 3920s suddenly losing the ability to connect to 2.4Ghz SSIDs in the last month or three)
Not sure you still have the SSIDs separate/Mesh mode disabled (you really should), but since the 4620 is dual-band you should try connecting it to the 5Ghz SSID (may require moving it temporarily) just to verify that it can.
As for the 2.4Ghz connection issue, try all the steps @AvsGunnar suggested.
(and disable "B" mode for everything unless you have very old legacy devices that require it)
1) Network connection reset: Settings/System/Advanced system settings/Network connection reset - try again
2) Factory reset: Settings/System/Advanced system settings/Network connection reset <---last resort, try again
You need to post more information and/or start a new thread.
Roku model # and firmware version: Settings/System/About
Name of ISP, modem/router/gateway brand/model # & firmware version, basic WiFi information of modem/router/gateway.
There is phone support, but it is limited to account/billing issues and first time setup/activation for now.
Otherwise, depending on your model, there is email/chat support: https://support.roku.com/contactus
I have the 3920. Firmware is... (going off memory) 10.0.0.492. I could have the last numbers transposed.
ISP is Ziply DSL (formerly Frontier).
I have 3 WiFi base stations.
#1 - Standard Ziply DSL modem. It does have mesh enabled. I have disabled it, reenabled, rebooted it & Roku with mesh disabled. SSID does not appear in Roku list, nor can I add it manually as a private network. Roku formerly worked fine with this base station.
#2 - Older Netgear WSR614v10, latest firmware. Connected via Ethernet to Ziply modem, but running in a different subnet. It does not support mesh, nor is is ac-band capable. B/G/N only. Tried all combinations of it's Wifi settings along with Roku/Netgear reboots. I currently have it manually assigned to Channel 6. It does not appear in Roku available networks, nor can it be added manually as a private network. Roku formerly worked fine with this base station.
#3 - Ancient Netgear WRT model, b/g band only. It is in extender mode off of #1. This is the only SSID Roku now sees. Unfortunately, performance on this router is very poor, which is why I want to connect to #1 or #2.
I have reset Network settings multiple times on Roku. Countless reboots in various orders of the Roku & wireless stations. I have tried shutting off #2 & 3, with no success.
As noted on my original post, this whole setup, messy as it may be, worked just fine with regard to the Roku until sometime in the spring. I suspect Ziply pushed out a firmware update the enable the mesh mode. However, that does not impact the wifi settings of Router #2. All other devices in the house connect without issue to all 3.
Unfortunately there have been many reports over the past few months (coinciding with the release of OS10) of 3920's losing most/all connectivity.
At this point, though you are past warranty, I suggest you message @RokuDanny-R or contact Roku directly, they may be able to help:
https://support.roku.com/contactus (choose setup/ultra/other/need more help?)
Otherwise, consider replacing the 3920 with a Express 4K+ (3941) for $30-40. They are dual-band and USB-ethernet capable.
Check https://my.roku.com/upgrade/ to see if there is an offer for one, otherwise:
