I have two working like new Centurylink GreenWave C4000XG wifi 6 Fiber gigabit modem/router for sale. The price is $35 for each.
Note that this modem/router has wifi 6 (aka wireless AX) which really makes a huge difference for wireless speed and connectivity over the older wireless AC technology. Most current phones and computers can use this for a real wireless speed and coverage boost.
I decided to go another route for my modem, and have this one up for sale. It has the latest firmware on it, and has been reset back to factory settings. It includes the original power adapter.
Centurylink charges around $200 for these, or if you are renting their modem, around $13 a month, so this will pay for itself rather quickly.
This will also work with Quantum Fiber if you are on an older plan and your rented or owned modem dies. (Centruylink and Quantum Fiber are both subsidiaries of Lumen Corp, their parent company.)
Important note -- this can ONLY be used for their fiber service -- it is not a DSL or VDSL modem. It can be used for any of their fiber speeds from 20Mbit up to their highest gigabit service. If you are still connected using their DSL or VDSL via copper pairs, and fiber is available to your location, you can usually get them to convert your connection at no cost and get the same download speed, but will double your upload speed and the reliability of your connection will be greatly improved.
(I've put a few things to consider when choosing between Centurylink Fiber and Xfinity coax internet at the end that might be helpful.)
I can deliver this for $40 to Portland or any of the near east suburbs, $60 to the western suburbs and the far east suburbs.
Thanks for looking!
You can call me at the number above between 10am and midnight, or send me an email using the link above. Please DO NOT text, as I often don't see them.
Please note I screen calls from unknown numbers, so please leave a message the first time you call indicating who you are, your phone number, and what you are calling about. I'll call you back. Once I know your number I'll add you to my known contacts after that, and answer the calls directly.
Some details about my CL postings:
1. I delete postings within minutes of them selling -- if it is still posted, I still have it -- so please don't ask if it's still available, I won't answer -- (too many CL trolls out there looking for email addresses to spam).
2. I only sell locally and for cash
3. I only reply to emails via the Craigslist relay, so please don't ask me to reply to another email address. If you buy from me, I am willing to share my direct email info, but not before.
4. Again, I do screen calls from unknown numbers, so please leave a message the first time you call indicating who you are, your phone number, and what you are calling about and I'll call you back. I'll add you to my known contacts after that, and answer the calls directly.

For those considering between Centurylink's fiber and xfinity via coax cable, here are a few things to consider that might be helpful:
1. Xfinity has a data cap on their plans, and if you go over that, they will charge you extra. Centurylink does not.
2. While xfinity says they offer gigabit service, what they don't tell you is that the local "pipeline" your data goes through is shared with their other customers in your neighborhood -- so when all the folks start streaming when they get home from school and work, you'll likely see your speed suffer. Centurylink's fiber is a dedicated connection to their main hubs -- with little to no impact due to neighboring customer's use.
3. In my opinion, both internet providers have lousy customer service. You'll hear horror stories about dealing with both of their customer service folks. Just be prepared to deal with this, and make sure your bill reflects what was promised. It may take a call or two to get things straightened out any time you make a change in your service. The most effective way to get the best deal with both of them is to threaten to disconnect, and get transferred to the "retention" department, who will often have better deals available and are better trained than the normal customer service folks.
4. Xfinity offers special 1 year deals, but then jacks their rates up at the end of that year. They are notorious for this, and you have to call them every year to see if you can get a "deal" again. These "deals" often require term commitments. They also are known for increasing their added "fees" pretty much annually. Centurylink offers "price for life" plans, and once on those plans the rates won't go up (but they won't go down, so keep an eye out for rate reductions, and get them to adjust your plan to the lower rate).
5. Both internet providers have been known to offer better speeds for the same price as they charged for the lower speeds. However, they often won't tell you when this occurs, and they often won't automatically bump up your speed. So it is often a good idea to review the available plans periodically to make sure you are getting the best speeds possible for your dollar.
6. I believe both internet providers have customer referral bonuses available from time-to-time -- so if you are getting new service, see if your friends who use the service could get a bonus for referring you (and you might get a few dollars too for being referred).
7. Wifi is a nice convenience to have, but to get the best possible speeds in your home wired connections will always be faster. If you have a laptop that has an ethernet port on it, try running an "internet speed test" both using a wifi connection and then (with wifi turned off) using a wired connection -- you'll likely be surprised at the difference. This is true for smart tvs too. If you are getting buffering when streaming 4k video or doing cloud backups using wifi, try using a wired connection to your modem/router, and you'll likely see the buffering disappear. There are flat ethernet cables available now that can be hidden under rugs that will eliminate the "bump" caused by round ethernet cables -- Amazon is likely to be the least expensive place to get them.
