You can actually find plenty of modems that are just plain ol' modems. Both $Senseless and I have this modem.
Also, depending on the $ISP, you can use your own modem as long as it is listed on their website of approved devices.
You don't even need to call Comcast. I just started using this modem last week and installation consisted of plugging it in and attaching the coax.

I use this Netgear and it's been perfect
I use the Netgear CM400 Modem , it is "approved" by Comcast and easy to set up. Then I use the Netgear R6400 as my router. Both very easy to setup and I get much better speeds now and my network doesn't stop once a week like it used to.
By law they’re required to let you use your own hardware if you have it. Easy to find on amazon, got my modem for 50 (NETGEAR CM400 https://www.amazon.com/dp/B0111MRLES?ref=yo_pop_ma_swf)
So I just upgraded myself and I'm on Xfinity (Comcast) also. Check out the comcast Modem combatiblity list here. I first got a refurbished Arris SB6121 and long story short I nor Comcast could get the Modem to activate. Then after doing some research I picked up the Netgear CM400 New for $60 and its been working great thus far. Since I only need 802.11n wifi capability I decided to get a TP-LINK N450 for $30. But if you want a bunch of bells an whistles or 802.11ac its gonna cost you. Everything I purchased seems to work great, the new router reaches all the way to my upstairs bedroom chromecast, I highly recomend any TP-Link wifi router they have all worked great in the past. Hope I helped.
I have RCN and bought this modem and haven't had any trouble:
NETGEAR CM400 (8x4) DOCSIS 3.0 Cable Modem. Max download speeds of 340Mbps. Certified for Xfinity from Comcast, Spectrum, Cox, Cablevision & more (CM400-1AZNAS)
Link here
I got tired of my cheap-o wireless routers needing to be reset every other day so I splurged on this one and it's been worth the extra cost. I've had to reset it maybe once in the last 7 months.
Linksys AC1750
Doing a quick look your Asus has good reviews, which honestly surprised me as I can't find anything that mentions it having 5GHz or AC wireless. As for your modem it has mixed reviews stating its about 8 years old now and from what you are describing there is a good chance that it needs a Firmware update that might fix the issue but since you don't own it, it's something Comcast would have to do.
Personally, I also have Comcast (Great Lakes region) with download speeds "up to" 75MB and my speed test just pulled 63MB down and 7MB up. I ended up buying my modem so I can lower my bill and I run a Linksys router without issue.
So, long story short, I would try testing your system with a cable right into the modem. Though inconvenient it will let you know if it's your router or modem is the issue. I find it unlikely that it is having a hard time routing the traffic from all your devices and more likely that it's an issue with the modem itself. And as it's a rental you'd have to call Comcast to have them test and either replace it or buy one yourself and then call and have them set it up to their network.

Cheap an works great
This! Sort of...
For one, you will need a cable modem:
Why multiple options and price-points?
In a nutshell, download and upload bonded channels supports how much up and down bandwidth your cable modem would have. 8 (8 download) x4 (4 upload) theoretically supports 340 Mbps download and whatever upload speed. My current 2x2 supports 125+ Mbps download.
Why get something beefier? You will get slightly better performance if each bonded channel isn't operating near it's ceiling. With Comcast, they have 16 and 24 download channels in most markets so that will help with your overall connection. Also having 24 or 32 download channels will help you break through speed barriers if Comcast offers faster connection speeds in the future.
Personal Note: I pay for 100/10 from Comcast and bought the $90 NETEAR CM600-100NAS Cable Model 24x8 Bonded Channels for my new home. While the theoretical download speed from the modem far out paces what I will get from Comcast, the new modem will take full advantage of the 24 bonded download channels in my area.
Then you will need a router. With Ubiquiti, you can really go with one of two router options:
There's a lot of YouTube videos that will explain the differences between each router. The short version is that they use the same hardware and have all of the same features available if enabled over command line but:
Personal Note: I bought the EdgeRouter X because the price point is so good. This thing EASILY out performs my Linksys WRT 1900 AC or any other Linksys, Asus, etc. routers that I have ever owned. With that said, I will never fully leverage all of the controls in the UI and I wish I had gone with the USG as it integrates with the Unifi cloud stuff. I will eventually switch to a Unifi router.
Then you will need an Access Point (AP) to create an access point for your devices:
If you get the EdgeRouter X, get a UAP-AC-Lite. They both operate off of 24v so you can do Cable Modem -> 24v POE power injector (comes with the UAP-AC-Lite) -> EdgeRouter X -> UAP-AC-Lite. This is what I have now.
You can upgrade to the UAP-AC-LR which has the longest range of all of the Ubiquiti APs or the UAP-AC-LR because of it's 3x3 MIMO which gives it a higher input/output than the rest of the Ubiquiti 2x2 MIMO. The latter two devices use 48v POE injectors.
Personal Note: I'm using two UAP-AC-Lites in my current two story home and will transition to four in my new three story home. Even at the cheapest price point, these far out perform the other routers and access points that I have ever owned.
I too was looking for a clear answer. I did my research so here you go. This can support your 75 Mbps

Are these good for speed? I work at home so fast connection is important. Is there a faster hardware that I should consider?
You mention that the installation guy will just come turn on the modem. Do we even need the guy to come if we buy our own stuff? Can I be the one that "turns it on"? Also, I am also ordering a home phone service and cable so he may need to come anyway?
Buy your own modem : Amazon Link
So you would probably want the EdgeRouter X - it's pretty basic, but for your use it should be more than enough. I have an EdgeRouter Lite, the two are similar, but the EdgeRouter X is PoE, a little slower, and has switched LAN ports (doesn't matter for your uses).
I don't know much about modems, but you want to get one that's basically "all modem", since your EdgeRouter is going to be doing all the routing for it. I went with this one but I'm sure there are better options.
You can then plug in the AP wherever you want on the internal network. Could be directly to the router, doesn't matter. You will need to use something called PoE - you can either pass that through the EdgeRouter X or use the included adapter directly in-line. It's not complicated, just take a sec to read the instructions. :) Basically you just need to make sure you plug the AP into the correct port, else you could damage things. It's pretty evident.
As far as which AP you buy... Well, it's up to you really. This would probably be fine, but they also have long-range and AC versions. I've tried the Long-Range version and it's not super impressive. Not tried the AC version yet because very few of my devices actually support it sadly.
Let me know if you have any questions!
Any modem on the list will be fine. I bought this one, it was the cheapest with a brand name I trusted at the time. It's been great for 6 months.
Thanks for your insightful reply! I ended up going with a Netgear CM400 which I believe is DOCSIS 3.0...More recent reviews mention it working with Comcast. My only concern is the reliability because it seems like every modem/router we've ever used always hiccups and needs to be restarted constantly. Hopefully all works out! So done with paying Comcast that "f you" fee
EDIT: I thought it wasn't supported by Comcast at first, but it was there!
Not sure if this is the right place to post this but looking for advice..
So I'm looking for a new router and modem to upgrade my current one and thought I'd ask for some suggestions.
Currently I've been looking at the ASUS RT-ACRH13 Router and the NETGEAR CM400 modem.
My current internet plan is 100/15 and looking to spend under 130$. Thanks for any help guys!
I would suggest googling your models and seeing what the specs are, and comparing those to what's available today. My bet is that it's time to upgarde. I'm not a super tech-y person, but buying a new router (having bought my old one only 3 years earlier) made a HUGE difference for me.
As for your modem, make sure yours is DOCSIS 3.0 or better. In most situations, you want 8x4 channels or better, too.
This is the modem I have: https://www.amazon.com/NETGEAR-download-Certified-Cablevision-CM400-1AZNAS/dp/B0111MRLES/ref=pd_sim_147_2?_encoding=UTF8&psc=1&refRID=A76TFGV21W579DWMC6BK&dpID=416Y7zgKuBL&preST=_SX300_QL70_&dpSrc=detail
Just based on age, I'm thinking yeah, probably time to upgrade. I can't seem to find solid data, but as my memory serves me, the average household broadband connection at that time was 5 or 10 mbps. Hell, when I got my first Charter package in 2012, the best I could buy was 30mbps (vs. 100 or 120 when I left in August 17 though I couldn't get that speed at my house). And I would think that the mid-market technology available at the time would have been created for that kind of output vs what we have today.
This is a really cheap($44) modem that works find with their 100Mbps. I then also have a Netgear wireless AC router.

Sorry for the late reply, here is the Modem. I can't remember the one they gave me, I do know I had to return at least 2 of them over the course of 2/3 years (tech support requested that I return them). The thing to do is to go HERE and pick one that is more than your max speed that you are paying for (please note that the modem I linked before is actually rated 3.4x what they have on their site, which I think is a screw up on their chart). Basically, as long your modem's Mbps is higher than the speed your paying for, you're good. It's also a good idea to have some extra to grow into. I would shy away from the wifi modems. I prefer to handle all wifi access via a router (a Wi-Fi modem is just another security hole and you should always have a router just for troubleshooting and it's an extra security layer). Also, here is the ROUTER I paired with the aforementioned modem. They've worked pretty much flawlessly for over a year and it costs about $80-$90 for both. You can certainly find more robust systems, but this is a really good value in my opinion.
Maybe you have already attempted it, but have you tried using your own modem/router? It sounds like you are using one provided by Spectrum. The modems/routers/gateways that ISPs provide are usually garbage.
 
I'm also an avid gamer and way back when I used to think these problems were all ISP controlled. Then I learned that router/modem instability can also cause these problems, independent of your ISP -- and to be completely clear, I think ISPs are evil, but it's not ALWAYS their fault. For example, your router or gateway could just straight up suck and cause packet loss, which is why you're experiencing the problems that you are.
 
It's a pricy one-time investment, but to me it's 100% worth it to avoid disconnects, etc. You'll also want to consider whether you want a gateway (a "modem/router-in-one") or a separate modem/router. I trust internet advice (maybe I shouldn't) so I got a separated setup (See: http://www.tomshardware.com/answers/id-3064021/modem-separate-wifi-router-modem-router-combo-unit.html)
 
Examples:
Outdated and I think overpriced because it's old hardware, but I've been using this combo:
-Modem (Had this for like 3-4 years and still going on strong): https://www.amazon.com/ARRIS-SURFboard-SB6190-DOCSIS-Cable/dp/B016PE1X5K/ref=sr_1_4?s=pc&ie=UTF8&qid=1496277630&sr=1-4&keywords=modem
-Router (had this for 1-2 years and very rarely do I have problems): https://www.amazon.com/TP-Link-Archer-Wireless-Gigabit-Router/dp/B00BUSDVBQ/ref=sr_1_1?s=electronics&ie=UTF8&qid=1496277752&sr=1-1&keywords=archer+c7
 
I did a quick Amazon search and found this much cheaper modem: https://www.amazon.com/NETGEAR-340Mbps-Spectrum-Cablevision-CM400-1AZNAS/dp/B0111MRLES/ref=sr_1_3?s=electronics&ie=UTF8&qid=1496277801&sr=1-3&keywords=modem
 
PS. Yeah Spectrum sucks. I saw my bill almost double and I'm considering going to AT&T in my area for at least 1 month just to get the promotional pricing. I think at worst I could switch back to Spectrum and maybe get promotional pricing?
 
Edit: Forgot one more important point: make sure your modem is "compatible" with Spectrum (or whatever ISP you go with). In most cases, if you buy a modern one, you should be fine (google DOCSIS and read a little about it).
Could consider this modem, it will work with most cable providers:
https://www.amazon.com/NETGEAR-340Mbps-XFINITY-Cablevision-CM400-1AZNAS/dp/B0111MRLES/ref=sr\_1\_1?s=pc&ie=UTF8&qid=1484281897&sr=1-1&keywords=cable+modem#Ask
Your ISP should have a "supported modems" list. If not you can roll the dice and just get a Docsis 3.0 modem like: NETGEAR DOCSIS 3.0 340Mbps Cable Modem for XFINITY, Time Warner, Spectrum Cable, Cox, Charter, Cablevision (CM400-1AZNAS) https://www.amazon.com/dp/B0111MRLES/ref=cm_sw_r_cp_api_2z-nzbWX75MZ8
Of course if your ISP has Docsis 3.1 you will be missing out.
Maybe you can try this.
This will handle a 50mbit hookup just fine: https://www.amazon.com/NETGEAR-340Mbps-Spectrum-Cablevision-CM400-1AZNAS/dp/B0111MRLES/ref=pd_lpo_vtph_147_lp_t_4?_encoding=UTF8&psc=1&refRID=AFX8YDJ68JE7ZAK7T356
Well, from looking at it you probably spend around $120 on the netgear you have now, and for the price you can get a basic DOCSIS 3.0 modem like this, and this Asus AC router for about the same price, maybe even less depending on how you order it. This is the same setup that I put together for my mom and sister a few months ago, and they are both pretty heavy netflixers and downloaders, and they have not experienced any problems.
I've had one of these with time Warner for a year without any hiccups: https://www.amazon.com/NETGEAR-340Mbps-XFINITY-Cablevision-CM400-1AZNAS/dp/B0111MRLES. I would hook up one of these as a router as well: https://www.amazon.com/gp/aw/d/B00DWFPDNO/ref=mp_s_a_1_1?ie=UTF8&qid=1486478904&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=asus+n300&dpPl=1&dpID=31vLTXPU-2L. If you're OK with switching between the devices using a single wire then disregard the router entirely, but you'll be limited to wired devices only.
Easy peasey:
Modem: Netgear 8x4
Router: Edge Router X
Access Point: UAP-AC-Lite
This will be absolutely rock stable and will max your speeds easily. Will require you to do a tad bit of setup but it's very easy. If you need an explanation on why this is better than something you could buy at BestBuy let me know.
Netgear would probably be your next best bet for reliability. I personally have only used Arris Modems as they're pretty much the gold standard but this Netgear had good reviews and cheap.

So could I get a router like so and just connect the coax in my room to it and then use the ethernet jack? Or do I need to just the main one in the living room?
This is to avoid wiring the cat5 through the wall

Notice the used prices...
While modems are hard to come by in the trash, routers are really easy to find. People get rid of their cheap N-routers all the time. A cheap N-router will still beat the hell out of your G-router.

Ok. Here's the modem I'd recommend and if you're on campus on a Wednesday night (7-11p) during semester come find me in the TUC, ask for Christian.
Hmmm. I already own my own router, it's a Belkin N150. I did a google search and found this NETGEAR DOCSIS 3.0 340Mbps Cable Modem that seems to be compatible? I'm wondering if my extra router (not currently being used) would work well with that modem.
Their compatible modems are found here. They don't specify what model they would provide.
