Get the 8, 8a, 9 or 9a from the station. The 101 is the dedicated match service that goes to the Ricoh. It's about a fiver and leaves from Pool Meadow. Other buses that go up there are the 4 and 5 to Tesco & the 13 from the Belgrade Theatre that goes more often (once you get to the last stop walk 50 yards to the railway line and take a right, you can see the ground from there). The 4, 5 and 13 are cheaper, £3.90 for a day saver which you can buy and use on all National Express Cov buses all day including those I've listed above from the station.
