WiFi 7 with EIR or Virgin Media's Wifi 6 for NBI preorder

Someone mentioned here in the last few days that Eir will be upgrading NBI 2Gb services to 5Gb soon for the same price. Personally I'd pick Eir over Virgin. I find Eir today different to the Eir most had the misfortune of doing business with a few years back but their customer care has improved massively and their FTTH is excellent to be fair. I did a bit of digging on their website last week and it says if you sign up in March, you won't be charged the increase in that coming year.

I can't guarantee you it's correct but the T&Cs from Eirs site says the following https://www.eir.ie/annualpriceincrease/
Customers that re-contract in the month of March will not be subject to the annual price increase until April in the following year (for example, a customer that re-contracts in March 2025 will not be subject to the annual increase until April 2026). 

I don't think there should be an issue. You're well within your 14 day cooling-off period if ordered online or over the phone, 30 days if ordered door-to-door sales.

No. The line is the same only until it hits your providers own network.

Eir exchange almost all of their traffic with the global internet here in Ireland, Virgin do the vast majority in Amsterdam.

On a good day, you'll probably not notice it - maybe slightly higher pings for Irish based servers as it has to go to Amsterdam and back.

On a bad day - and there have been plenty in the past - bandwidth heavy sites like streaming media or gaming download sites have been rendered unusable during the evening and weekend peaks for weeks to months on end due to congestion in Amsterdam.

Several massive threads here on Boards over the years of the various flare-ups where several industry heads pinpointed the exact issue and proved definitively it was within Virgin's network, while Virgin customer service (who were active here at the time) plain denied anything was wrong with their network whatsoever.

Only recently they were playing silly buggers with the upload speeds, users on here were reporting the sudden but sustained drop that was quite clear they had been deliberately reduced, with customer service outright denying there was an issue.

Another factor - may not impact you unless you're looking to host something on your own network - is Virgin do not give a publicly routable IPv4, it's shared with others. Only the IPv6 is unique to you. This prevents you being able to port forward anything from outside. It can also trip up some VPN's and some web firewalls (you get prompted with captcha's for unusual network traffic patterns). Eir does give you fully routable IPv4 and IPv6.

There is no CGNAT, you are given your own dynamic IPv4 address, with Virgin through NBI or SIRO afaik as it's the same as using a WAS-110, IPv6 is disabled.

Thanks. Jesus, they hate giving us upload! I’m in D3 suffering on 40MB/10MB with another year before FTTH will be available! Don’t want to go near Virgin Media.

This relates specifically to Clontarf. It’s at the planning stage with work only commencing in Q3 this year. They have been dragging their arse for years on this as it has kept been pushed out.
