Just remember if you do actually go Comcast, to do yourself a favor and buy your own hardware. Get yourself a good DOCSIS 3.0 modem (or 3.1 if you want to spring for gigabit) and a router that won't bottleneck you.

I've had Comcast for multiple years in multiple apartments, both in college with 2 roommates and post grad with my gf. Outside of the outage from like 2-4am once every 4ish months give or take, I've always received the service I paid for. I won't try and say they're a company ran by good people (they're not), but the service is reliable if you get the right hardware for the job. The combo I linked ya would break even in under a year's worth of rental fees.

I have this modem and this router.

Also make sure they waive your initiation/installation fee of $49.99. I started the process online of signing up for service, realized the installation fee and closed out of the window. Optimum emailed me back literally a half hour later saying they saw that I didn't complete my order. I let them know that the installation fee was too much and they said they'd credit that back to me on my second bill, which they did.

I'm using the TC-7610 in Hamilton with no issues. Had to phone in to TekSavvy to get it activated as their modem list under packages didn't match the modem list when trying to purchase service.

I know it's not near as future-proof as the TC-7650 but at least it is a Broadcom chipset and cheaper than the TC-4300. I got mine for $38 in the US.

For routers, anything with decent reviews on Amazon will probably get the job done. I tend to go with Asus and TP-Link, but there are lots of good models out there. I've had mixed results with Netgear and Belkin in the past, but worth it if you find one on a good deal.

• Any of these TP-Link models would probably work for you.
  
• I would also highly recommend this T-Mobile branded Asus "refurb." (I've bought 3 of them in the past for various different uses, and they were solid each time).
  
  For a modem, anything DOCSIS 3.0 or up should do for most people. Eg:
  
  
• Linksys
  
• TP-Link
  
• Netgear
  
  Of course, if you have specific high-end needs, these might not quite meet those, but I doubt whatever xfinity has you using would either.

I have this modem I bought outright instead of renting from xfinity

TP-LINK DOCSIS 3.0 High Speed Cable Modem Certified for XFINITY, Time Warner (TC-7610) https://www.amazon.com/dp/B010Q29YF8/ref=cm_sw_r_cp_apa_A2i.zb0JC38JA

As for the router, I like Asus brand. Anything Asus that is dual band and has more than two antennae sticking out will go through walls better and be fast. .

If you already have WiFi routers (and I'd suggest you have separate WiFi and modem so they can be replaced individually) then all you need is this TP Link:
http://www.amazon.com/gp/product/B010Q29YF8?psc=1&redirect=true&ref_=od_aui_detailpages01

It supports most speeds that people use, and it only takes 5-6 months before it's pays for itself.

It's entirely possible I was only renting for 5/month because of the apartment complex. I wound up going with this modem and this router duo mostly because I'm not super tech savy and am trying to piece this together for the first time. to save money, I simply knew that paying to own was better than paying to rent.

Where the modem is place doesn't matter per say, but having the router next to a fireplace will cause a blockage for objects on the apposing side of the fireplace. Large objects such as a fireplace, is more difficult for the 5GHz band to penetrate, but not the end of the world depending on the home layout. The wireless will bounce around or revert to 2.4GHz.

Even at a special deal, I still do not agree with the 1GB internet speeds. I find that the new 200Mbps speeds are more than enough. Plus, it would mean a cheaper modem such as this one: https://www.amazon.com/TP-Link-TC-7610-Download-343Mbps-Certified/dp/B010Q29YF8/ref=sr_1_10?s=pc&ie=UTF8&qid=1537674121&sr=1-10&keywords=modem

As for the router, this again depends on your home size. You didn't mention the square footage, but I really, really enjoy mesh networks. I am bias for eero, but Linksys also makes a good mesh network kit. https://www.linksys.com/us/c/whole-home-mesh-wifi/

This was the exact modem I bought to use with Start.ca. Worked straight out of the box.

I got these 2 (for about 70 bucks)

I'd also recommend that you use an ethernet cable on your main computer, if you want to get full speeds. In my complex due to signal noise and such I get 66% of my full speeds over Wi-Fi.

You will always be better off with a separate modem and router. That one you linked is not even AC, only N.

I will link some models that together will perform significantly better than the one you linked. You could also get an even nicer router in your budget by getting one used/refurbished, but that probably isn't necessary unless you have lots of constant users.

Modem - $40

Router (Archer C7) - $65

I don't have any experience with that modem, but TP-Link is good value, and it is comparable to the modem you linked.

Idk much about comcast modems cause i have fios but the reviews seem good. I would urge you into getting a ubiquiti setup however I think for you since you wanted something good in your budget this setup should suffice. For the modem you should try to get as many channels as you can within your budget

If you only have the 75 Mbps plan, this is completely sufficient: http://www.amazon.com/dp/B010Q29YF8?psc=1

I set it up for my brother and it's fine. I also set up the following motorola one at my parent's place and it also works fine. No need to get a super fast one if you only have a 75 Mbps plan (both modems can go much faster than that too).

I have personally tested both on Comcast, the TP on a 75 Mbps and the Motorola on a 150 Mbps plan. Both get speeds over the plan's advertised ones. Course you still only get about 12 Mbps up because Comcast is lame, but if you need upload go look at their business class I guess. Either way, both of these modems are great and will saturate your connection both ways if you need to.

Edit: Added a sentence.

This one is cheap and seems good http://www.amazon.com/dp/B010Q29YF8?psc=1

Okay, so is this good or not?

As far as I know, All Xfinity is Docsis 3.0 This Modem should be great! Also if you need wifi too, you could get the TPLink Router modem combo

The only way you'd be wrong is if you have a modem in an environment that causes frequent failures, and of course even then you should probably move it. Renting ONLY makes sense, in my opinion, if you have them replace it more than once a year. Otherwise do some research on supported models and buy one that works for you. I would also recommend avoiding any "router/modem combos" as they're generally garbage.

Personally I have this modem: https://www.amazon.com/TP-LINK-DOCSIS-Certified-XFINITY-TC-7610/dp/B010Q29YF8/ref=sr_1_7?s=pc&ie=UTF8&qid=1509736005&sr=1-7&keywords=cable+modem

And this router: https://www.amazon.com/TP-Link-Wireless-Ethernet-Archer-C50/dp/B0168G0KZY/ref=sr_1_4?s=electronics&ie=UTF8&qid=1509736039&sr=1-4&keywords=tp+link+router

Purchased in a bundle together for $80 (it appears frequently if you watch for it) and they're great for the money. Do a little research, though, because different modems support different services so they somewhat depend on your internet service and routers are even more personal to your living environment and needs.

Below is what im currently using. I don't know much about modems, my initial assumption is that this one is fine, would anyone recommend replacing it as well?

If you are going to purchase a new router/modem, then I would buy those devices separately. What I mean is, purchase a modem which either works with DSL internet or Cable internet. Then purchase a router that meets your needs. Typically, the router that companies give out is actually a router and a modem in one. Separating those devices gives you better flexibility in the future. If you switch from DSL to Cable or vice versa, all you need is a new modem which is a lot cheaper than a modem/router combo. You could drop $300 on a super high-end router that won't need to get replaced if you switch to a different style of connecting.

You could purchase something like this TP Link Modem and this ASUS Router. Another company that a lot of people get routers from is Netgear. I stopped using their products after they wanted me to pay for their customer service on a product that was defective. I could understand if I broke the router, but the product never worked and now they wanted more money? No way.

You can do it with a modem alone, though most only have one input Ethernet port, so you'll be limited to one device, the PS4. A router allows you to use wifi and Ethernet for whatever you like. Since OP has a router built into his modem, it wouldn't work with just getting a new modem.

>are there good modems and routers that are under 100$ total that would be good

I haven't used these personally, but they'll work fine. http://www.amazon.com/7610/dp/B010Q29YF8 and http://www.amazon.com/dp/B003Y5RYNY You'll want to check what modems work with your ISP, though, as some modems might not.
