There are a couple of network connection problems recently being reported that have been caused by updates to routers. These have primarily been reported with routers supplied by internet providers, but it's possible they could also occur with user-owned routers that have received updates.
This may not be your problem but they are well worth looking into.
If you need to make configuration changes on equipment supplied by your internet provider but you have no access to its settings, you may need to request your internet provider to make the changes for you.
I'm a 54 year old grandparent, and after quite a bit of googling, searching, and trying, I was able to fix our Cox router so our Roku can work again. Can I tell you exactly what I did? LOL! I might be able to do it again, but it will still take time. I tried so many things it's hard to remember what finally worked! A lot of my IT fixes are like that. I screen shot what I changed and where I found it: After logging into our Gateway modem (Cox), here's the path Gateway>Connection>Status
If I can figure this out, you can too
Hope this helps someone
That worked! Thanks so much!
This is my issue. I can connect to phone hot spot but not my home wifi. I can see the router name in the list which says it is excellent signal strength but when I try to connect it fails I have a 3900x Roku Express. My router is Xfinity and all my other devices work. This started since the update.
@Karlmaloneand @Ophie01 , try these instructions for how to change the wireless mode:

You want to set it to b/g/n.
Thank you! It worked! I was about to trash my Roku! Xfinity said it was my Roku device, until I argued by reading the question and your solution. I had to create a 2.4 GHz network, which I guess is what you meant by switching back to 802.11 b/g/n. Agent No. 3 understood the issue and the fix, and walked me right thru it (compared to Nos. 2 & 3 who answered my "do you understand" by thanking and repeating my name 5 times while insisting the only fix was restart router).
I received the error message "Unable to connect to wireless network" with Error Code 014.30. The message suggests to restart the router and the Roku player. However, the router is not the issue because other devices connect, and multiple attempts to restart the Roku device did not resolve the issue. I understand that Roku is offering a software rollback available for issues caused by a recent update, but it is not possible to implement it without connecting to the internet.
First, who is your ISP? If it's a cable company, they might have made a change in your router that affects Roku connections. Especially if it's Comcast. Under the 2.4 GHz radio, there is a Mode setting. Your ISP may have it set to G/N. If you can access the setting, change it to B/G/N. If you can't access it, ask your ISP to change it.
Sometimes when you have a network issue, you can connect your Roku to a mobile hotspot and get the update in that way. If you have a smartphone, it likely offers a hotspot function.
I would also like to add that since the latest update, roku won't connect via wifi. Take note that I do live in a studio apt that offers both free and premium wifi (that you have to pay). I do find it annoying I was watching Roku just fine with all the apps working properly and then the next day their wireless connections doesn't work. The wifi works on my phone and laptop just fine.
@RikCamp see my response above. It's entirely possible your issue is related to the Roku OS, but it's also possible that your ISP changed a setting in the router that impacts a Roku connection. Sure, other devices connect fine, but that particular setting I mentioned could be the issue. Also, you didn't state what model Roku you have, if you're connecting to a 5 GHz or 2.4 GHz access point. It could make a difference.
